154CM favors abrasive edge retention; Nitro-V favors toughness. Their corrosion ratings are equal, so the useful decision is how the edge will be used and maintained, rather than which steel has the more impressive name.
Performance Ratings
For the science, we turn to Dr. Larrin Thomas of Knife Steel Nerds, who has kindly allowed us to share his ratings here.

Heat treatment, hardness and geometry affect actual knives.
Choose 154CM When Wear Is the Main Problem
154CM rates 4.5 for abrasive edge retention, compared with Nitro-V at 3. If your knife mainly slices packaging or other abrasive material, that gives 154CM a reason to be on your shortlist.
It does not mean a 154CM knife cuts one-and-a-half times as long. These are expert rating points, not cutting-distance ratios. A thin Nitro-V blade can still be the more pleasant cutter than a thick 154CM blade.
The 154CM steel profile gives more context for its wear-focused balance.
Nitro-V Leaves More Room for a Tough Edge
Nitro-V rates 7.5 for toughness and 154CM 3.5. For a knife where resistance to chipping is a major priority, we would give Nitro-V more weight than its lower wear score might initially suggest.
That advantage still needs a sensible edge geometry. A very thin edge, poor heat treatment or a twisting cut can cause damage in either steel. Nitro-V is not permission to use a cutting edge as a pry bar.
Our Nitro-V steel profile looks more closely at its toughness and care.
Rust Resistance Does Not Separate Them
Both score 7 for corrosion resistance in this framework. There is no basis here for treating Nitro-V as the clear rust-proof option or assuming 154CM needs markedly more care.
Wipe either blade clean after food or wet work. For sharpening, Nitro-V’s lower abrasive wear resistance makes it a reasonable choice if you prefer regular touch-ups over maximizing the time between them. Actual effort also depends on how much damage needs removing and the abrasive you use.
Think About How You Want to Maintain the Edge
We would lean toward 154CM for a pocket knife doing frequent, controlled slicing. Nitro-V is appealing when you value toughness and are happy to refresh the edge more often. That is a useful tradeoff, not a premium-versus-budget verdict.
Be sure a listing says 154CM, not CPM 154. They are related but separate materials, and the 154CM toughness score in this comparison should not be assigned to CPM 154.
