Tested most of my knives

For edge retention.

Now I did not do this very scientifictly, I do not have proper tools to meassure sharpness and I stopped the test whenever I deemed the sharpness had dropped where it was noticeable.

For testing the sharpness I used armhair and thin paper (thinner than regular printing paper) and paper towels.

The cutting media is a 1 inch thick hemp rope and I meassured the number of cuts. Hos legit the hemp is i do not know, i did match exactly the results of a youtube (Green beetle) with rhe mora garberg stainless whom's setup I tried to replicate.

The cutting surface is a plywood sheet.

I took meassurements of the knives spine edge and thichness behind edge around the area i used to cut (normally towards the front of the knife).

Like I said its just me testing my knives and while sone results surprised me you should not take my findings as gospel.
All my knives are sharpened by habd on either my cheap 4 sided diamond stones or the 325,1200 grit dual stone from sharpal and then stropped 5-6 times per side on leather with and without diamond emulsion 4 and 1 micron.

There are still some really heavy hitters I do not think I want to test as i suspect they would do above the 40 that the brisa did.

For example
Nordic knife design forester 100 in elmax and 62hrc.
Spyderco mule in magnamax and around 65 hrc.
Viper turn essential in m390.

And manly city in s90v.

If there is enough interest i can try those aswell.

Do these results surprise you? How important is steel vs geometry?
Hope you enjoy!
