What’s your sharpest knife?

[Randy Griffin]

My dad once told me how they used to sit around at work and see who could get their knife the sharpest. Said they could clip a hair. I have always been good at sharpening but never could clip a hair. Until I made a kiridashi from a ball bearing race. Show your sharpest knife.

My sharpest were obsidian, I don't know if I can find one. I may have to knock one off a core.

Clipping or splitting?I could not see in the video quality what you were actually doing

....clipping is imho easy but splitting is another deal.

Splitting hair is depending in which direction the texture scales of the hair is pointing.Also people have thinner or thicker hair....so splitting hair depends.

My sharpest knife is a straight paper thin ground razor, so thin, You are not supposed to cut something else than your beard hair.

So the conclusion is sharp for use or sharp for hair splitting contest.

The edge ground to 0,15-0,20 mm of thickness is the sharpest that makes sense to put on a knifes edge.

For some folks this is too sharp,too thin  they cannot handle this sharpness without damaging the edge

Cheers
