For many knife enthusiasts, it represents the closest thing yet to the “perfect knife steel.”
But does MagnaCut live up to the hype?
Is it truly better than M390, SG2, N690, 14C28N, or AEB-L?
Is it worth the premium price?
And is MagnaCut a good steel for kitchen knives?
In this complete guide, we’ll explore everything you need to know about MagnaCut steel.

What Is MagnaCut Steel?
MagnaCut is a premium powder metallurgy stainless steel developed specifically for knives.
Unlike many steels adapted from industrial applications, MagnaCut was designed from the ground up as a knife steel.
The steel was created by metallurgist Larrin Thomas, who spent years studying knife metallurgy and analyzing the strengths and weaknesses of existing steels.
The goal was ambitious:
Create a steel that combines:
- High toughness
- High corrosion resistance
- Excellent edge retention
without the traditional trade-offs.
The result was MagnaCut.
Today it is produced by Crucible Industries using advanced CPM (Crucible Particle Metallurgy) technology.
Why Was MagnaCut Developed?
Traditional knife steels often force users to choose between desirable characteristics.
For example:
High Edge Retention
Steels such as:
- M390
- S90V
- S110V
offer excellent wear resistance but can be difficult to sharpen and may sacrifice toughness.
High Toughness
Steels such as:
- AEB-L
- 14C28N
- 52100
offer outstanding toughness but lower wear resistance.
High Corrosion Resistance
Steels such as:
- LC200N
- Vanax
offer superb corrosion resistance but may sacrifice other properties.
MagnaCut was engineered to break this pattern.
MagnaCut Steel Composition
Typical composition:
| Element | Percentage |
