wheastone knife sharpner for 30 deg blades.
The knife sharpner is build for knifes with 30 degrees knife angle. if you have one different you may change it.
This is for a stone of size 180x60x30mm, if you stone size is different then make changes
The bearings used are cheap 608RS bearings. you will need 4
You will also need M2.5x10 hex socket bolt/screw. 4 in number and M2.5 hex nuts 4 in number
I used 4 magnets to stick at the back for the knife to be at place.
