Springloaded Handle for Knife Sharpening

Did a in my opinion better handle with a horizontal spring load instead of the squeezing in and screw in back fit.
It also helps with slightly different length and shapes of the stone, for the original one I had to file mine a bit to fit in the handle.

You'll need just two small nails on which the head needs to be cut off and a spring from an ordinary ball pen (I used one with 4mm diameter).

Also, I got rid of the longer grip, I found it uncomfortable and held the "original" one on the middle of the handle, for which I added a bump.


I used Sketchup and added the original Files for more customizing.

Update:

Antix in the comments gave me the idea to modify the base model further to a two and four stone holder.
I've updated my files, now you can find besides the old one stone holder a version for two stone (untested print and sharpening) and a four stone holder in two versions.
Version 1 (the one in the pictures) is assembled with three pieces, for the ease of printing
