All of the steels that you mention are great knife steels, and they all are super steels, they just are not quite a super as Maxamet. Para Military™ 2 Left Hand G-10 Black . Native® 5 G-10 Dark Blue CPM S110V. TWISTED SISAL MERCH - THANKS TO MISHEARDKNIFEREVIEWS: https://teespring.com/twisted-sisal-merch Remember to subscribe for more lunacy - hit the bell etc! S110V's data sheet mentions, for example, that it has better corrosion resistance than S90V. Learn more in this article about carbides. But not S110. Maxamet. Von Gesichtsrasur war ja ausdrücklich nicht die Rede. S90V offers somewhat better toughness and edge retention making it more balanced for applications that need only medium corrosion resistance. My guess is few heats of the original composition were ever produced, so experiments on that version are mostly academic at this point. It’s high-speed tool steel made by @CarpenterTechnology. Somewhat surprisingly, they both resulted in identical toughness despite the higher austenitizing temperature leading to higher hardness. In Stock . If you’re interested in the Maxamet steel for your knife, and still have doubts, I would like to assure you that’s it’s a great steel for your knife, depending on your usage, its has an exceptional edge retention and excellent wear resistance, but it’s low on corrosion resistance, so if you’re an EDC user (you like to have a tactical knife on you, for opening boxes and canes or whatever your bare hands can’t handle) it’s a great knife for you! Note that the values below are normalized to the hardness of the tested toughness specimens. You will also see I have two compositions listed for S110V, one labeled “patent” and one labeled “final.” The initial version of S110V was modified leading to the version that we have today. The M390 offers better toughness, corrosion resistance and it’s a bit easier to sharpen compared to the Maxamet, but for the edge retention Maxamet is the best. Es hatte geheißen, daß Armhaare nicht denkbar seien. CPM-S110V. They have the same blade grinds, and they are heat treated and processed by the same manufacturer, of course. Native® 5 G-10 Black. The blade features a full-flat grind, a distal taper, and an understated wedge. Eine extreme Legierung mit unglaublichen Härtewerten und einer atemberaubenden Schnitthaltigkeit. Spyderco Para Military 2 Knife. This was confirmed in tests reported in the patent, where a cobalt free version had some ferrite present after heat treatment, and only reached about 54 Rc. Different steels will transform to austenite at different temperatures. However, the patent for S110V specifically calls out 154CM as a basis of design with its 14Cr-4Mo, providing good corrosion resistance with less Cr, and that can be seen in the initial version of S110V with 14Cr-3.5Mo. Where a steel like S30V really shines is in sharpening. S110V and S90V are my favorites in the very high edge retention stainless steel category, depending on the level of corrosion resistance that is necessary for the application. $255.00. Well, it’s largely still up for debate but from my experience Maxamet matches S110V in edge retention but falls short on corrosion resistance (it’s not stainless). I have 2 spydercos in 110 and maxamet as well, and they have crisp edges as well. Since Nb improves corrosion resistance by helping the Cr go further, they may have attempted to compensate for the reduction in Nb by increasing the bulk Cr from 14% to 15.25%. As I wrote in my M398 article, I am not a big fan of the steel because of its coarse structure and relatively low toughness. But for simple slicing tasks, this knife will go on for a seriously long time. But I can get the S90 decently sharp. All of the following experiments were performed on the later version of S110V, as that is all that is available to purchase. I have a spreadsheet of all of the heat treatments I have done in the past along with ThermoCalc estimates of elements in solution. Therefore, the approach with S110V was to have a combination of vanadium and niobium to improve corrosion resistance as much as possible while avoiding issues that come along with excess niobium. 1 year ago. Pacific Salt™ 2 Black Blade. Chromium carbides are softer than vanadium carbides and therefore contribute less to wear resistance. I tested S45VN in my 1% saltwater spray corrosion test. I have not had hardness testing done on the S90V or S110V, only on the Maxamet, but I assume that Spyderco has a similar hardness level in both S90V and S110V. In fact the revised datasheet shows all of the same data for corrosion resistance, hardness, and wear resistance despite the fact that the change in composition was relatively substantial. The Manix 2 LW is available at most retailers for around $80.00. Es hatte geheißen, daß Armhaare nicht denkbar seien. $160.00. Opus™ $218.00 SALE. But, If you’re a Diver, Hunter, Kitchen Chef, or you use your knife in humid places, and you’re looking for premium steel, I wouldn’t recommend the Maxamet I would instead go for the S110V stainless steel. S110V and M390/20CV/204P do have higher Cr in solution than S45VN. Manufacturing Technology - MM. I will discuss the differences after describing more about the general design of the steel. The changes were likely made to improve “manufacturability,” such as issues with gas atomization, forging, or annealing of the steel. $205.00. $216.00. Micro Melt Maxamet Alloy can be supplied as steel plate/ sheet, round steel bar, steel tube/pipe, steel stripe, steel billet, steel ingot, steel wire rods. The patent for S110V and the original datasheet released in September 2008 (I archived it here) is the original composition labeled as “patent” in the composition table. S110V's data sheet mentions, for example, that it has better corrosion resistance than S90V. Maxamet is a powder steel from Carpenter, an American steel company. CPM-S110V. You’ll find Maxamet on some Spyderco offerings like the Native 5 and Manix 2. All of this in combination with the powder metallurgy technology gives S90V a relatively fine microstructure for good toughness along with high wear resistance from the high vanadium content. $217.00. The Griptilian is comfortable but it feels totally different in your hands versus the PM2. So being conservative we would say that S90V is tougher than S110V which has higher toughness than S125V. Replacing nickel with cobalt in 316 would not make it hardenable has it would still need significant amounts of carbon to form hard martensite. Your email address will not be published. The reasoning and test results seem totally convincing, but I can imagine companies preferring to stick with the steel makers reccomended heat treatments. Spyderco Native 5 Lightweight Dunkelblau Klappmesser Taschenmesser C41PDBL5 CPM-S110V 4,4 von 5 ... vs the Sage 5, but not enough to stick with the lock back. As mentioned in the niobium section, there are limits to niobium alloying with typical powder metallurgy steel production. One of the major changes that was being made to S110V when compared to S90V/S125V was the addition of niobium. Through over a month of consistent use, my Paramilitary 2 blade was still sharp enough to slice through phone book paper and stick against my thumbnail. However, niobium is a “stronger” carbide former than vanadium, meaning it can form niobium carbide even in the presence of high amounts of chromium. Maxamet ist der neueste Pulverstahl von Carpenter (auch bekannt als CarTech). Native® 5 G-10 Black. So sharpening these knives to a keen edge with ceramic involves crushing those carbides (near the apex) into “nano-dust” and burnishing the matrix around them. Und das ist definitiv falsch. I used Jmatpro software to calculate a steel with the same compostion of 316 stainless steel : 18%Cr + 2%Mo but with replacement of nickel with only 5% cobalt and 0.5% carbon . Although Maxamet isn't stainless, but at the same time Maxamet is tougher compared to Crucible CPM S110V steel, which can result in better edge holding ability, and cutting performance with the right geometry and heat treatment. the effect of cobalt on raising martensite start temperature inspires me an idea . I am glad that I bought this one. With increased Cr in solution, but decreased Mo, it is not clear which version would have superior corrosion resistance. Understand that a keen edge requires a dimension of around 100nm (1/10 of a micron) and the vanadium-rich carbides in Maxamet, or S110V, or even the chromium carbides in ZDP189 are 1-2 microns in size. CPM-S110V exhibits many of the same qualities as S90V. As a side note, both the original and new version of the S110V datasheet shows the following for heat treatment/hardness data: However this primarily shows the hardness that results in the upper tempering range, where Mo has the biggest effect on hardness. regarding the problem of formation of large carbide particles , isn’t ball milling considered the most effective way to refine the carbides down to optimum size for edge retention/toughness combination ? That method has its own issues such as many carbides clumping together, in general PM steels have a more uniform microstructure. Maxamet is a powder steel from Carpenter, an American steel company. Manufacturing Technology - MM. Its an extreme alloy with insane hardness and tremendous edge retention while still retaining a reasonable amount of toughness but at the expense of corrosion resistance (it’s not stainless). Each knife comes without scales or … Or maybe they thought it gave a bit more “factor of safety” to ensure full austenitization would be possible. $230.00 . $230.00 . $217.00. Although Maxamet isn't stainless, but at the same time Maxamet is tougher compared to Crucible CPM S110V steel, which can result in better edge holding ability, and cutting performance with the right geometry and heat treatment. In my original corrosion resistance experiments with 1% saltwater I found S110V to have very good corrosion resistance, certainly a significant upgrade over S90V and S125V, and being similar to M390, another grade with very good corrosion resistance. electroslag, forged ring/ … The 11V steel would still be an upgrade over S90V for corrosion resistance because of the higher Mo in solution (see the Molybdenum section later on in this article). The results can be seen below. I swap the parts around. Subscribe to our newsletter to get a free guide on ”your subject”. Manufacturing Technology - MM. Where a steel like S30V really shines is in sharpening. The cobalt content was increased from 2 to 2.5%, likely based on updated estimates of how much austenite stabilization is necessary after the changes to Nb, Cr, and Mo. I do emphasize with the guy who chipped his blade, but I do find Maxamet to be less fragile than S110V. Like many other very high wear resistance stainless steels (S90V, M398) it was developed for plastic injection applications which necessitate a combination of high wear resistance and high corrosion resistance. I do emphasize with the guy who chipped his blade, but I do find Maxamet to be less fragile than S110V. I don’t know the cause but I’m convinced it’s a real effect. The Mo content of M390 is lower, however, so it is difficult to predict how things balance out when comparing higher Cr vs higher Mo. S110V has a similar Mo content as well so it should still have better corrosion resistance than S45VN. I won’t buy S110 anymore even though I admit it is good on paper. However, a full replacement of vanadium with niobium is difficult to do. Furthermore, there is some chromium present in vanadium carbide, further reducing corrosion resistance. Para Military™ 2 G-10 Dark Gray Maxamet. $160.00. In this section, we’re going to compare our steel with other steels, and for this, I use four criteria; Edge Retention, Corrosion resistance, Ease of Sharpness, and Toughness, and I use a scale or note from 1 to 10. It's cool to carry a knife made from Maxamet, M390, or CPM-S110V. using 5% Ni instead gives Ms of about -66°C (-87°F) . Regardless, the development of S30V and S125V meant that Crucible metallurgists were well aware that Mo could improve corrosion resistance with the same level of chromium. The reduction in Mo from the original version (3.5%) to the final version (2.25%) likely means that these values are no longer accurate. Native® 5 FRN Pink. Ball milling is used to refine carbides when they are added directly to powder, such as adding tungsten carbide to steel powder prior to HIPing. One of the best knives you can get if you’re looking for high-quality steel and premium design, the NATIVE 5 is a beast that combines strength, superior cutting performance, edge retention, and point utility it comes with a grey, injection-moulded reinforced-fibreglass-nylon handle, the Native 5 has a back lock mechanism and a four-position pocket clip, which makes it very comfortable and efficient. Sharpness: Sharpening Maxamet steel, unfortunately, will be a hard task, it’s very hard steel, so sharpening won’t be easy, also for grinding if you’re a knife maker you won’t enjoy grinding Maxamet steel. I have asked current Crucible metallurgist Bob Skibitski as well as the main inventor on the patent, Alojz Kajinic, and neither knew why the change was made as they were not directly involved with it. No matter for me. I didn’t mention clogging of the nozzle in this article as that is not the only issue. In Stock . FYI the maxamet manix is a lightweight without liners and is pinned. $305.00. But I still don’t know for sure why S110V wasn’t as good as S90V in testing. For example, S90V edge retention is closer to M398 when at the same hardness. I'm still curious to see a custom knife made out of Maxamet though. Or very high toughness with AEB-L or 14C28N. Even with that handicap, it’s a great knife. The patent for the steel was first filed in 2006 by inventors Alojz Kajinic, Andrzej Wojcieszynski, and Maria Sawford, all of Crucible Steel. I prefer the S35vn blah on the LW scales. MAXAMET and S110V both share a low toughness, Maxamet offers better edge retention while the S110V offers better Corrosion resistance. In an alloy, Tungsten contributes to the harden-ability, and with this much Tungsten it’s no surprise that Spyderco hardened Maxamet up to 67-68 RC. But the chromium increase was more than was necessary to achieve a similar amount of chromium in solution (see the table below), and they also decreased the Mo content by a similar amount to how much the Cr was increased (from 3.5 to 2.25%), so the reason for that change is not completely clear to me. Go buy one for yourself, and everyone you know, as a Christmas present. maybe if alloyed with niobium carbide the hardness will be raised somewhat . S110V Steel is more balance compared to the Maxemet, as you can see, Maxamet offers extreme edge retention in the cost of other criteria. That said, S30V is a great steel! Whether this was due to a problem that was observed in production or simply being cautious I am not sure. Para™ 3 G-10 Dark Gray Maxamet. These heat treatments all included a cryo step after quenching. ... S110V. The carbide volume of S110V is closer to S125V which is significantly coarser. I haven’t performed a full range of heat treatment experiments on S110V, but comparisons with S90V show the two heat treating relatively similarly. Native® 5 FRN Dark Blue CPM S110V. According to the chemical composition and the HRC of the Maxamet steel, it offers the following features: Edge Retention: With a hardness above 65HRC, due to the high amount of Tungsten, Vanadium, and Carbon, the Maxamet steel knife has the best edge retention. The Mo content of M390 is lower, however, so it is difficult to predict how things balance out when comparing higher Cr vs higher Mo. In my original edge retention article I speculated that perhaps the smaller carbide size was the difference and I made some comparisons with the size of the abrasive particles used in the testing. Below I have plotted the steel also in relation to other stainless steels along with a hardness-toughness trendline from S60V. I'm still curious to see a custom knife made out of Maxamet though. Get Up To 95% Off Today! And in the more recent comparison directly with M398, S110V again performed similarly. There are no knife steels with corrosion resistance equal to 316, perhaps Vanax or LC200N approaches 304 but it depends on what type of test is being performed. The Spyderco Para Military 2 - What more needs to be said? The Maxamet steel in considered as a “Super Steel”, So it’s a High-end Alloy steel, with an uncommon chemical composition, but I can say that the closest one to it is the CPM S110V(even if it’s stainless steel), in exception of wear resistance; the Maxamet is a great match for the S110v in edge retention, hardness, wear-resistance and price range which is between 100-200 Usd. In an attempt to clear out some of my unused knives, I’m putting up some of my Spyderco Mule Team blades. S30V is not in the same wear resistance class as the other steels, but the design of that steel may have influenced the others so I included it. I then calculate Ms and plot vs hardness to see where hardness starts to drop from excess RA. there is no doubt that if all of these 10% carbides are vanadium or niobium carbides instead of mostly M6C carbides which are much softer the hardness will be increased slightly , while the edge resistance will be increased greatly and still retaining the same toughness . It's cool to carry a knife made from Maxamet, M390, or CPM-S110V. Pacific Salt™ 2 Black Blade. My Native 5 in Maxamet is the only one of my 3 Native 5’s that I have had Rockwell tested and it came in at 67 HRC. Using the numbers 0.5% carbon and 18% Cr Ms is too low for avoiding excessive retained austenite. S110V is designed to be heat treated between 2050 and 2150°F so the steel would need to be austenitized in that range. vasco MA which contains only 0.5% C reach a maximum of 62 HRc while the M2 can reach 65-67 HRc due to presence of about 10% volume of undissolved carbides . And with some users reporting difficulty in deburring S110V (usually means high retained austenite), I’m not sure I would actually recommend heat treating S110V from 2150°F despite the apparent superior hardness-toughness balance. $145.00. Und nach meinen Recherchen spricht einiges dafür, daß S110V zäher als S90V ist, also etwas weniger zu Ausbrüchen neigen sollte. (This is not heat-related). That said, S30V is a great steel! Para Military™ 2 G-10 Digital Camo. $217.00. See more hardness measurements of S90V in this article. If you frequently use your knife to slice up cardboard, there may not be a better steel than CPM-S110V. Previous steels like S60V, Elmax, and M390 all had 17-20% Cr which gave them more chromium carbide and less vanadium carbide. In terms of carbide differences, the total carbide content was slightly increased in the final version, primarily from an increase in chromium carbide (labeled M7C3 below). Micro Melt Maxamet Alloy can be supplied as steel plate/ sheet, round steel bar, steel tube/pipe, steel stripe, steel billet, steel ingot, steel wire rods. However, this steel has high hardness and corrosion resistance which can mean excess retained austenite which sometimes leads to inflated toughness values. Auch von einer Ruinierung der Schneide kann nicht die Rede sein. Sie ist lediglich nicht mehr fein geschlossen. I imagine a steel combining the corrosion resistance of marine-grade 316 stainless steel with the edge resistance of M4 , 15V or even Rex121 in the near future . Read all 5 Reviews » Paramilitary 2 Series. As mentioned in the article deburring is mostly an effect of retained austenite, and the recommended heat treatment for the steel isn’t necessarily the best for avoiding it. (from my limited experience and the specific design goals for … And if the formation temperature is too high, carbides will form in the melt before the steel can be gas atomized to form the powder. In Crucible’s wear resistance testing of the original S110V, they show the following chart for wear resistance, that appears to show an improvement over S90V: However, if you plot those values versus hardness it becomes apparent that the two steels have the same wear resistance: So Crucible’s data shows that there was no improvement in wear resistance from S90V to S110V, which lines up relatively well with our edge retention testing. But S30 at least eventually gets sharp, S110 never does (for me). Model # SP-C81GPDGY2 . $305.00. The matrix of high speed steels contains only between 0.4-0.6% C , so 0.5% C seems to be enough for reaching high hardness . With that said, the difference between the 2 is that the 0888 is uncoated and comes with a composite S110V and 14C28N blade, while the 0888MAX is black DLC coated and approximately half of the 0888MAX knives feature Maxamet steel, and the other half have M390 steel bl… Matching 316 corrosion resistance while also reaching 60+ Rc would be very difficult even with cobalt. ... S110V. Native® 5 Salt® $186.00. This might be happening because the knives are from different manufacturers, using different heat treat and blade grinds? S90V and S110V both offer superior carbide structure and toughness when compared with M398. $250.00. Model # SP-C81GPDGY2 . However, an increase in both Cr and Mo means a significant improvement in corrosion resistance for S110V. I'm still curious to see a custom knife made out of Maxamet though. This does not appear to be an issue of experimental variability as none of the tests performed on S110V resulted in as high values as the average result of S90V (each was tested 3 times). MSRP: $295.00 Was: $295.00 Our Price: $206.50. A smaller amount of harder carbides (like vanadium carbide) gives a better combination of toughness and wear resistance. most of these carbides are of M6C type while only 1.7% by volume is vandium carbides . The steel has good properties including high edge retention and corrosion resistance along with decent toughness. Here is the datasheet. FYI the maxamet manix is a lightweight without liners and is pinned. However, S90V and the modified S110V (labeled 11V) have 11.5% Cr in solution while S110V (9Nb-3.5Nb) has 12.3% Cr in solution, which would provide better corrosion resistance. All PM2s are great at EDC tasks. Maxamet is the latest powder steel from Carpenter (aka CarTech). $295.00. This will be relevant to the toughness discussion later on. I don’t know how much S110V would have been made into knives before the change in composition, but it is interesting that a relatively large change was made to the steel but without a name change. Although Maxamet isn't stainless, but at the same time Maxamet is tougher compared to Crucible CPM S110V steel, which can result in better edge holding ability, and cutting performance with the right geometry and heat treatment. The Spyderco Para Military 2 - What more needs to be said? The obvious answer is Yes, its prey good for knives, especially if you’re looking for a knife with excellent edge retention and very high wear resistance, Maxamet is a “Super steel” for your knife, but it’s not a stainless steel, it has only 4% of chromium in it, so it’s not so great concerning corrosion resistance. The standard blade steel of the Native 5 is CPM S30V stainless steel, but Spyderco has expanded that offering with additions like super high-grade CPM-S110V and Maxamet steels. The results of these … If they found a small amount of ferrite in S110V that would have contributed to the decision to increase Co, of course. all powder metallurgy fabricated by hot isostatic pressure which is sooo expensive , adding a ball milling step just add a little to the cost . I have two Spydercos in S110 and a Benchmade in S90. You can see the difference in the micrographs below. I can get the S90 much sharper than the S110. S110V and M390/20CV/204P do have higher Cr in solution than S45VN. Elmax. If you ever wanted to own or buy a knife with excellent edge retention, I m sure someone already recommended the Maxamet steel as steel for your knife, and if you’re reading this blog post, it means you wish to know more about it. Buy Spyderco Native 5 Signature Folder Knife with 2.95" CPM S30V Black Steel Blade and Black FRN Handle - CombinationEdge - C41PSBBK5: Pocket Knives & Folding Knives - Amazon.com FREE DELIVERY possible on eligible purchases Para™ 3 G-10 Black. $160.00. I didn’t know how realistic is Jmatpro but I’m sure that 0.5% carbon should secure 55-60 HRc hardess . If you’re looking for an EDC knife with a Maxamet Steel, the  NATIVE 5 is your choice. I have the Maxamet LW version, the pink S30v, the Satin blade natural G10 with M4, and the original (discontinued) G10 with liners and S35vn. why didn’t just replace the nickel in 316 steel for example by cobalt to make such steel “hardenable” ? As a rule, the harder the steel, the easier it breaks, so the Maxamet steel is very hard steel that can break very fast, but it’s tough enough to handle some beating, damaging work. Von Gesichtsrasur war ja ausdrücklich nicht die Rede. If you are unfamiliar with the Para Military 2, this will help you get a better understanding of one of the most popular knife designs in the past 10 years. I have seen almost no discussion of the change in composition, and I think most people are unaware that it ever changed. I covered the history of them in more detail in a previous article. Because niobium is a strong carbide former, it wants to form carbides at very high temperatures, often in the liquid steel. Also, the chromium “in solution” to contribute to corrosion resistance was actually improved in S90V relative to the earlier S60V by careful control over the carbon and vanadium content, despite the bulk chromium being lower. S110V is a very interesting steel because of the innovations that went into its development, including a niobium addition for improved carbide structure and corrosion resistance, and cobalt addition to ensure it could be heat treated despite the excellent corrosion resistance. Spyderco ParaMilitary 2 Dark Gray G10 Stonewash Maxamet C81GPDGY2 . As you can notice, it has only 4.75% of Chromium, which means its not stainless steel, and it’s very high in Vanadium and Tungsten, which makes a tough alloy with excellent wear resistance. Native® FRN Grey Maxamet. A similar comparison was made in the patent, as 11% V is roughly equivalent to the V-Nb combination in S110V. WTS--Spyderco Mule blades (MAXAMET, K390, S110V, CTS-XHP and Cobalt Special) Prices reduced . According to @Cartech, the Maxamet has a maximum hardness of 70HRC. Required fields are marked *. However, more carbon means more carbides which reduces corrosion resistance and toughness, as described in this article. S110V is essentially S90V with more C, Cr, Co, Mo, and Nb, and it is difficult to think of scenarios where adding more of those elements would lead to reduced edge retention. Become a patron and gain access to awesome rewards including early access to articles or a Knife Steel Nerds mug! $305.00. Same techniques and tools – DMT plates, ceramic rods, diamond paste strops. $200.00. Here is the datasheet. But for simple slicing tasks, this knife will go on for a seriously long time. Spyderco Military Left Hand Black G10 Plain Edge Satin C36GPLE . You’ll pay for it though, at roughly 1.5x the price. The s110v blade of this Manix 2 blurple is very very sharp so be careful with it. Through over a month of consistent use, my Paramilitary 2 blade was still sharp enough to slice through phone book paper and stick against my thumbnail. I tested two conditions of S110V, one austenitized at 2050 and another at 2150°F, with both tempered at 500°F. P'Kal™ G-10 Red Trainer. I was curious to have first hand experience with this steel. Die Zähigkeit ist angemessen hoch, jedoch auf Kosten der Korrosionsbeständigkeit (nicht rostfrei). There was a somewhat surprising and little discussed composition change with S110V, for mostly unknown reasons (though probably related to manufacturing). The corrosion performance didn’t seems impressive . Very interesting article. The test produces a number for each steel of rope cuts made, so steels can be placed in a hierarchy where the interested person can get a decent idea of where one steel might sit against another. The reduction in Nb may have led to the other changes in the steel. Maxamet ist der neueste Pulverstahl von Carpenter (auch bekannt als CarTech). What is its chemical composition? There is another aspect of S110V vs S90V that I would like to mention. P'Kal™ G-10 Black. I did a large number of edge retention experiments which were summarized in this article, and I also added M398 which was discussed here. Maxamet’s distinguishing metallurgical characteristic is the high carbon content (2.15%) and the inclusion of 10% Tungsten. This improvement in corrosion resistance was expected based on the modifications with Nb and Mo that were described earlier. Both are ridiculously difficult to sharpen. $310.00. In an attempt to clear out some of my unused knives, I’m putting up some of my Spyderco Mule Team blades. All PM2s are great at EDC tasks. Spyderco ParaMilitary 2 Dark Gray G10 Stonewash Maxamet C81GPDGY2 . To put S110V into context, we should compare the composition of the steel with previous Crucible products to see how the evolution led to S110V. Both of these steels are a real bear to sharpen up! Not as sharp as steels like AUS8, but pretty sharp. There is hardenable stainless steels with just 0.03% carbon . $236.00. If you are unfamiliar with the Para Military 2, this will help you get a better understanding of one of the most popular knife designs in the past 10 years. and again adding fine carbides will adds to both hardness and edge resistance . This behavior was seen with M390 when austenitizing too high.
