Good edge retention, toughness, and sharpenability, D2 has been a popular knife tool steel dating back to WWII, and for good reason. In its composition this steel is close to the Japanese steel of AUS-8 grade. In order to improve corrosion resistance and toughness, a secondary tempering process can be selected. CPM-S110V exhibits many of the same qualities as S90V. Heat Treatment is the process of hardening and tempering the blade steel through heat. Bohler M390, CTS-204P, and CPM-20CV are all essentially the same steel and sport a near identical composition. S30V is, in many eyes, the ultimate EDC steel. It really depends on what you're doing with your knife.

The following are deserving of mention, but there are just not enough knives produced from these steels to give a rating. that section. Realistically, in normal day to day use you would struggle to pick out any differences in comparison. Excellent strength and toughness are balanced with very good sharpenability and corrosion resistance. 8Cr13MoV steel is made by Chinese stainless steel manufacturers with reference to AUS-8 stainless steel produced by Aichi steel, and its naming method refers to GB/T 20878, GB/T 1220, GB/T 3280 and GB/T 4356 (see notes below). AUS-6 vs. 440C/8Cr13MoV. M390, 204P, and 20CV are all durable steels that sacrifice ease of sharpening. Additional considerations include the thickness of the blade stock and the primary grind. Certain steels are so good at resisting rust and corrosion that they can be left abused and salty without ill-effect. Notes: GB/T 20878 – Stainless and heat resisting steels designation and chemical composition.

Sal Glesser described XHP as a combination of D2’s hardness and 440C’s corrosion resistance. The effect of heat treat varies based on the composition of the steel. CPM-154 is an excellent EDC blade steel with above average edge retention, corrosion resistance, and ease of sharpening. Compared to forged steels, powdered metallurgy based CPM steels have a very fine grain structure and far fewer inclusions. Buck widely uses 420HC in their knives to great success. But what is the best knife steel? Sharpenability is pretty self-explanatory, but softer steels can be touched up in the field on that big elk hunt. Updated by Blade HQ Staff Trevor Brown and Andrew Hamilton on 3/1/2019.

Cutting and slicing performance improves as the thickness behind the edge decreases. Where a normal steel would chip, these knives can sustain intense batoning sessions, power through staples, and glide through steel strapping. Popular among both Benchmade and Spyderco, CPM-S90V is a knife steel known for its excellent edge retention and very good corrosion resistance. 52100: AEB-L: ATS-34: RWL-34: ZDP-189: ATYPICAL STEELS. It's considered Stainless Steel. This is a small list of steels that aren't necessarily in high production anymore, but still offer high-end or mid-range performance.

While H1 steel lives in a specialist category as a fishing or boating knife, LC200N holds its own as an EDC knife steel. Sharpening goes hand in hand with blade geometry. 8Cr13MoV steel at its low cost demonstrates very worthy characteristics of cutting. Sandvik steels are largely found on affordable, entry-level knives. Consider Elmax if toughness is high on your list.

Essentially, CPM steel (also called powdered steel) is produced from a very fine powder of carbide particles. Remember that in addition to steel, geometry and heat treatment both play a huge role in performance. Based on experience and testing, M4 steel may outperform blade steels such as M390 and S90V in terms of edge retention and M4 is in a completely different league in terms of toughness. Chinese 8Cr13MoV stainless steel can be quenched at 1050 °C to obtain the highest hardness value, the Rockwell hardness can reach above 62 HRC, high hardness helps to improve the sharpness and wear resistance of the knife. Maybe one of the most frequently overlooked aspects of blade steel is sharpenability. The best blade steels exhibit a balance of strength and toughness. Tough blade steels are ideal for camping and hard-use. BD1 is a great entry-level steel. In contrast, a thicker blade stock with more material at the edge will yield a tougher, less slicey knife like the Ka-Bar Toughness is key on hard-use camp knives and fixed blades. This steel has been used to make high quality knife blades. Don’t know 20CV from M4? Often overlooked is the job at hand. The chart below shows how amazing H1 steel is in every category except edge retention. The charts below aid visualization of the strengths and weaknesses of a particular knife steel. Equally at home as an EDC folder or as a fixed blade, this blade steel is easy to sharpen, corrosion resistant, and mixes very good edge retention with sufficient toughness. I'm curious because the SS Delicia and Endura are AUS-6 and wondered how they stack up to the byrds. Give this article and each knife steel chart a gander, and you’ll be halfway to an Ivy League degree as a metallurgist (no uhh…not really, but we all start somewhere). experience.
