maximising edge retention, A study


Recommended Posts

Tough there is a difference between rigidly fixed blades in a machine and free hand led blades.

....the cutting test machine gives information about wearing resistance of  the alloy / the steel...for precise non-dynamic cutting action

but blades that are hold and used free hand experiencing a lot of different angles and stresses on the edge.

It says very little about edge performance of hand knives, the knives we are dealing with the most

Altough interesting.... Thanks for sharing!

Hi Tempelhound,


Agree, but I would think that to study edge retention when using a knife free hand would be difficult. too many variables to be able to draw conclusions.

I was nevertheless less surprised by the fact that edge angle has a greater influence on edge retention than hardness.
