D2 is also fairly hard to sharpen. There is a reason you see so many knives with those 2 steels. The S35VN and D2 are probably the best balance of edge retention and ease of sharpening. CPM S35VN 12.0 ft. lbs. [/quote] Sounds about right. 154CM 2.5 ft. lbs. Stubborn to get sharp but also stubborn to dull. Steel is essentially an alloy (i.e. I think of that whole group of steels (s30v, s35vn, s90v, s110v, zdp) as stubborn. Both S30V and S35VN steel are made with the same carbon and chrome content, and from various tests, both steels provide the same edge retention and corrosion resistance. Although the longitudinal toughness of all four of these grades is about 25-28 ft. CPM S35VN and S45VN Developed and made by Crucible Steel in the United States. Data tables . Little more edge retention, but a little less edge stability (which is fixed with a micro bevel). S35vn and S30V which are pretty much the same steel as far as the end user is concerned is a little step up from the 154cm and CPM154 steels. S35VN is not too bad, but M390 is about as hard to sharpen as I care to have. Advantages: Toughness, wear resistance, corrosion resistance. CPM S35VN Steel Review Chris Reeve Knives PacificWhen Crucible Industries introduced its CPM S30V steel, blade-smiths and knife-lovers alike fell in love with it; the quality wear resistance, toughness, and machinability offered by the steel was equal to none other. By Larry Connelley When looking at quality American-made knives, you'll notice that S35VN and S30V steel are two of the more popular steels for knife blades. Taking the best toughness results and plotting them vs other stainless steels shows that CPM-154 compares favorably to other PM stainless steels, similar to S35VN and better than steels like Elmax, Super Gold 2, and S45VN: Previous CPM-154 Toughness Measurement ... Like 154CM, there is a newer version, S35VN… The S35VN or CPM S35V is a high-end martensitic stainless steel made by @Crucible, high in Carbon, Vanadium, and chromium designed to offer a great balance between toughness, hardness and corrosion resistance.It’s used in long-wearing Specialty cutlery, Plastic Injection and Extrusion Feed Screws and Dies, Wear Components for Food and Chemical Processing, and of course in the Knife Industry. ZDP-189, S90 and S110…nope, I will pass on trying to sharpen those. CPM S35VN. lbs., the transverse toughness of the CPM grades is four or more times that of 440C and 154CM. People were calling it, “the best knife steel available,” and indeed, it might have been. CPM S35VN is a martensitic stainless steel designed to offer improved toughness over CPM S30V. Note: There is a powder-metal version called CPM154 that’s purer than the non-powder version, making it easier for knifemakers to grind. a mix) of carbon and iron that is often enriched with other elements to improve certain characteristics depending on the desired application. So CPM154 will do a marginal bit better in cutting. Data tables above sourced from CPM S35VN and CPM S45VN data sheets from Crucible Industries. Alongside edge geometry and design, blade steel is a critical element that determines how a knife performs. That goldielocks zone of good cutting performance and ease of sharpening is hard to get. CPM S30V 10.0 ft. lbs. Its chemistry has been rebalanced so that it forms some niobium carbides along with vanadium and chromium carbides. I would classify BD1n in that zone. CPM-154 Toughness Compared to Other Steels. In choosing the best pocket knife you should pay particular attention to the type of steel used in the blade. The higher transverse toughness results indicate that CPM S35VN and CPM S30V are It is also easier to machine and polish than CPM S30V. 440C 2.5 ft. lbs. What it is: CPM S35VN is a "Crucible Particle Metallurgy" stainless steel, an improvement over CPM S30V, and is widely regarded as a "super steel" for its properties and performance.
