It's basically the same idea, just an incredibly barebones version of it :)Ankerson wrote: ↑Mon Mar 05, 2018 1:39 pmI use the KN100 Sharpness tester, but everyone has their own ideas.Vivi wrote: ↑Mon Mar 05, 2018 1:37 pmsharpness testing is legit and easy to do at home. Somewhere I can scrounge up the setup I made. Simple little block of wood with a nail hammered into each side and a V shaped notch on the top. Loop some sewing thread around both nails and push cut straight down on the thread with the block of wood resting on a postal scale.
The sharpest factory knives took about 80g of force to push cut the thread. Most factory knives took 120-150g of force. My hand sharpened knives, mostly VG10 and S30V finished with a DMT fine stone at the time, got into the 30's.
Maybe I'll get one of those some day.
They aren't cheap, it's the media that really makes the difference though I think, it's very consistent. Makes no difference about temperature, humidity etc.
For me it's just another data point before testing.
