Knife sharpener

This is a knife sharpener with double guides.
It is made of 3d printed parts, M5 threaded rod, and 8mm aluminum solid rods as sliding axles for the stones holders.
The stones are from online shops but any stone can be used as they are only glued onto the sliders.
You will need 1/2 meter M5 threaded rod and 1 meter 8mm aluminum rod, solid or hollow, a few m4x25mm screws and nuts and M4 eversize washers.

The locking knobs for adjusting the axles angle have a washer embedded during printing.
