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.
There are three holes on the bottom plate to fix it to some heavier plate or to the bench if you want to sharpen both sides at the same time, otherwise just hold it by the handle.
There are also some plates to use it with suction cups.
There are two different knife clamps, one can fit a metal plate.
There are 4 different sliders, one for stones
