. . . . . CPM 20CV. What it is: CPM 20CV is a "Crucible Particle Metallurgy" stainless steel, widely regarded as a "super steel" for its properties and performance. Advantages: Outstanding edge holding and corrosion resistance, requires little maintenance. Disadvantages: Very difficult to sharpen. Who uses it: Bark River Knives. . .
. . . . . . . The CPM 20CV steel excels in terms of overall toughness but can be a bit brittle to sharpen. It can perform a variety of tasks without any problems. Looking at applications, the S30V is brittle and hard to sharpen. This means it's not ideal for high-impact applications like lever work, digging, and sharpening. CPM 20CV vs. 154 CM.
. . . . . They are using a guided sharpening system which does not allow them to use high sharpening pressures. This is a legitimate reason. Traditional stones do need higher pressures to cut high-carbide steels well. Because diamond stones can only be used with low sharpening pressures they are well-suited to guided sharpening systems. 3. . .
