CPM 10V is a non-stainless powder steel for frequent abrasive cutting. It offers more wear resistance than many general-purpose knife steels while retaining more toughness than extreme-wear choices such as Maxamet or REX 121. That balance is useful when long slicing sessions matter, provided corrosion care fits your routine.
What Is CPM 10V?
CPM 10V is a high-vanadium powder metallurgy tool steel. Its selected specification lists 9.75% vanadium, so the grade name is not an exact percentage. This profile covers CPM 10V itself rather than transferring specifications from other similarly composed tool steels.

Edge Retention for Abrasive Work
10V scores 8.5 for abrasive edge retention. That is above CPM M4 at 6 and below CPM 15V at 10 in this framework. It is a meaningful option when a knife repeatedly wears dull through slicing rather than failing through chips.
For light, occasional cutting, you may notice blade geometry and handle comfort more than that wear resistance. A high rating is useful only when it addresses the work you actually do.
The Balance Between 10V and 15V
Its toughness rating is 5, compared with 15V's 3.5. That makes 10V a less extreme wear-focused choice, though it remains below tougher grades such as 4V and 3V. Treat the comparison as a way to choose priorities, not a guarantee against damage in a particular knife.
Our 15V profile looks at the opposite side of that tradeoff: more abrasive edge retention and less toughness.
Sharpening and Non-Stainless Maintenance
Diamond or cubic boron nitride (CBN) abrasives are useful for 10V's vanadium-rich carbide structure. Start coarse enough for any repair and keep the bevel consistent as you refine the edge. Touch-ups before major wear sets in can reduce the amount of metal you need to remove.
10V has a corrosion-resistance rating of 4. Clean and dry it after use, and use suitable protection during storage when needed. For a knife that regularly stays wet, a more corrosion-resistant grade may be the better compromise even if it has a lower wear rating.
Who Is CPM 10V Suited To?
10V suits someone who does enough abrasive cutting to value its wear resistance, has suitable sharpening equipment and accepts non-stainless care. It is worth comparing with 15V when you want more toughness, or with M4 when a more moderate balance is appealing. Let the actual knife's geometry, heat treatment and ergonomics remain part of that choice. Our knife steel guide helps compare the alternatives.
