Ergonomic "Fingergrinder" 4 Knife Maker

Heyho

I watched a video a while ago and saw this type of tool. I think this could be very usefull and safe the one or other hand from getting sanded away or burned :D

However, after some searching, I couldn't find it anywhere for sale. So i designed my own version of it.

This is a replacable and ergonomic version with the intention to give some grinding actions more security. I also have the ide to combine this version with some brass elements to screw on.

But first I want to know if this is a good tool at all. I used it for some knifes and I am still unsure about how useful it is.

So test it out and give me some feedback!

Have fun and keep grinding!

// The more heat resistant the material is, the better.
// Print with 100% infill.
// Avoid seams, where the knuckle touches.
// If you have very small or big hands scale the model down or up :)
