I can think of two plates of steel, the M390 from @Bohler and  CTS-204P from @Carpanter, the three of the steels have a close chemical composition, and they offer the same properties (High edge retention, high corrosion resistance, high wear resistance, toughness, and hardness), and they fall in the same price range. Welcome to Kershaw Link 20 CV Review with SKU 17760 again USA made. While M390 does have a higher overall value than Maxamet, the way I see it is that Maxamet has higher edge retention and wear resistance.

It's the same as M390/204p so there's a ton of information out there concerning it. If you can’t afford the M390 buy an S35VN that’s my ultimate advice! Toughness is the maximum amount of energy a material can handle before braking. CPM 20CV is a martensitic steel, which refers to its hard crystalline structure with lens-shaped or lenticular grains. Der ZDP 189 ist ein Stahl mit extrem hohen Kohlenstoff- und Chromgehalt, wodurch die Messer einen sehr hohen Härtegrad erhalten. I have all 3 from the same brand (20cv and m390 PM2, 204p Military; and m390 and 20cv from Hinderer or ZT). A material with higher hardness usually has a lower toughness and vice versa.

Just got a 20CV full size Griptilian, so we'll see how that is. M390 exhibits excellent edge retention, corrosion resistance, and high level toughness. Even with it being a non-stainless steel, M390, CPM-20V, and CTS-204P still don't perform as well. CPM-20CV is Crucible’s version of Bohler’s popular M390 steel which also influenced Carpenter to copycat with CTS-204P. “Quick Stop” If you have no idea about “Rockwell Hardness” You must read this post then comeback! Just a great compromise of wear resistance, toughness and corrosion resistance. The S110V comes in the same level with the M390 in edge retention ease of sharpness, and corrosion resistance, but with a lower toughness. 1. share. is the measure of a material resisting a scratch, wear or abrasion. The Benchmade Barrage 581 Knife is a Drop point Knife with Satin finish, belt with the M390 Steel, its a standard Clip type, with a reversible Tip-Up clip position, unfortunately, it’s not belt for glass breaking, its has a beautifully designed G10 handle (You can buy it with an aluminum handle), its has no sheath, no lanyard hole and it’s not Molle compatible.

Made by @Crucible CPM 20CV is a martensitic stainless steel high in Vanadium, Chromium, and Carbon for excellent wear resistance and corrosion resistance, it’s used for plastic injection feed screws, barrel liners, screw tips, mold cavities, and premium Knives. CPM 20cv Sharpness: the harder the steel to harder to sharpen it or grind it, this applies to our CPM 20CV, it’s a very hard steel that olds edge for a long period, therefore sharpening would be an occasional activity, but won’t be easy. Martensite forms when austenite cools so quickly that the carbon in the steel supersaturates a special … M390 vs S90V (CPM S90V) M390 Benchmade 20cv is outstanding in my book. According to the chemical composition and the HRC of the steel, the CPM 20cv Steel has the following features: CPM 20cv Edge Retention: CPM 20CV offers excellent edge retention due to the high carbon, high vanadium and high chromium in it. Too common to be called "Hype". The M390 STEEL is a popular premium steel that fits perfectly for knives, it offers all the specs to enjoy a high-end knife (high corrosion resistance, excellent edge retention, great toughness), and that explains the expensive part of the m390 steel knives.Truth to be said you won’t regret buying an M390 Knife!

This is somewhat annoying because I was not sure what the difference could be attributed to. First the blade its made from the premium CPM 20CV that offers great edge retention, corrosion resistance and wear resistance, the blade has a beautiful Hinderer flat-ground and comes with a handle that has carbon fibre front scale and stonewashed titanium back (Oh my god! It’s a great tool for outside usage (Climbing, hunting, camping), and it has a great toughness, great edge retention and high corrosion resistance. Across the board the predicted CATRA measurement is lower than what was measured, averaging 142 mm lower, or 122 mm if the Spyderco M390 knife is ignored. Gekko … M390 and M4 have both same edge retention and toughness, the difference is M390 is better in corrosion resistance and a bit easy to sharpen compared to the M4.
