I Tested the Edge Retention of 48 Steels

Give me 62 Hrc any steel and i will destroy it on bone, stone, other steel, wood. German meat cleaver cuts bone on 56Hrc better than knife on 56 Hrc. If you cut paper with knife or shave hair with knife that doesn't mean that is knife better than scissors or razor. This is real meaning " right tool for job", not different knife or steel.
Well I guess my real world experience of butchering a decent amount of animals with different steels and hardness is completely irrelevant as you are telling my results are false.

Have fun in your bubble.

Oeps….I thought/ hoped this conversation had stopped …Please🙏
 
I made a custom CATRA blade in Dr Larrin's new high edge retention steel called MagnaMax,

I traveled to Golden, Colorado to test it in the Spyderco laboratory.

The amount of cards cut on the first stroke was very impressive.

Overall, if comparing to other steels and the geometry and hardness are normalized for an apples to apples comparison then It is definitely in the K390/10V range 🤙

That’s nice to hear about edge retention of that blade in the new steel. Stainless K390 like……🥰
How about the chipping/rolling ( edge stability/ toughness) in comparison when hardened to the hrc the steel was tested at? And at what hardness was it tested?

The edge stability will be highly enjoyable but results generally speaking will vary like it always does with any steel due different processing, HT, sharpening etc.


This CATRA blade was at 66.5rc so it was attempting to test the limits of the material.


The future looks bright.
