However, M390, CTS-204P, and CPM-20CV are all pretty difficult to resharpen, so maintain that edge! This is an old high-carbon (non-stainless) steel. The steel was developed by Maria Sawford as a modification of S30V by reducing the vanadium content, adding 0.5% niobium, and removing the nitrogen addition (incidental nitrogen is still present). Knives are one of our oldest tools, so it makes sense that they have evolved into thousands of styles since the first person chipped one out of stone. CPM 154 Steel CPM 154 steel is a high chromium stainless steel knife, boasting a hardness, corrosion resistance, and edge retention superior to that of other steels such as 440C and D2 steels. This steel does have excellent wear resistance. Spyderco is the only production company using this steel, though Michael Gavik of Gavko knives produced a number of customs in LC 200N. D2 ... it’s a truly superior steel. And while it can be hard depending on the heat treat, I have found it easily chips, causing microscopic dings in the edge when hardened to a high level on a thin blade. Most steels use carbon to increase hardness, but 14C28N uses nitrogen, boosting hardness without the normal penalty of increased corrosion. Geronimo. To ref back to your article here, for the money, D2 or 154CM fits the bill for me so long as the price point is the same for either, sometimes they can charge a lot for D2 and I would rather have CPM-M4 in that case. One of the more common stainless steels, and one readily available in lots of different places worldwide, AUS-8 is a decent all-around steel. CPM American Steels Both S35VN and S30V steels were developed in a collaboration between Chris Reeve and Crucible Industries, a New York-based steel manufacturer, using Crucible Particle Metal (CPM) technology. That change set the bar for all mid-range Cold Steel products for the next three years. However, when pitted against S35VN steel… It was an uncommon steel… December 7, 2020 Larrin.

Produced by Crucible looking to make minute improvements to their S30-V stainless, a retuned chemistry based on vanadium and chromium, the addition of Niobium improved toughness and wear resistance over other stainless steels such as 440-C. CPM s90v Corrosion Resistance: Great Corrosion Resistance due to 14% of Chromium, which makes s90v stainless steel (Once steel has more than 10-12% of chromium in it it’s considered stainless steel). Are these "Exclusive Dealer Runs" ever announced beforehand? I’ve found S35VN less chippy even at the same CPM S30V or S30V Steel? In use, it’s very similar to 440C and VG-10. Pro 1000 Instead, Vargo titanium uses a unique material called sintered titanium-ceramic alloy. I saw a Youtube rope test video between the two blade steel's and I tell you what. AEB-L is rarely found on production knives but can be found on custom knives easily. In my experience, it's easier to get a very thin, very sharp edge with CPM S30V than with D2. It is also easier to machine and polish than CPM S30V. Crucible's goal was to create an even tougher steel that didn't sacrifice resistance to corrosion, and they did that by using niobium carbides in place of some of S30V's vanadium carbides. This guide explains important features to consider when buying a new knife for the outdoors. Time and use have proven this to be quite accurate. Or do they just appear one day? When it debuted, Sal Glesser described XHP as a combination of D2’s hardness and 440C’s corrosion resistance.
