KME to EdgePro/Hapstone Knife Sharpener

thingiverse

I had a KME sharpener and wanted the best of both worlds. With a simple change of the nut, you can quickly use your KME rod and stones on a EdgePro/Hapstone like base. This allows you to slide the blade and get a consistent angle on long blades. Thanks to CNC kitchen for his base design. I used this to quickly model out a replacement clamp and set of guide rails. The clamp is removed from the KME and the plate is set aside (you just need the KME ball joint and nut). There is a straight rail included like the EdgePro and for more complex spines, the toe guide works like the Hapstone. I still haven't found out an ideal way for magnets that can be engaged and disengaged easily (there are 3 sets of holes in the bottom of the base that will allow you to install a few 10mm x 2mm magnets and epoxy them in. I personally haven't installed any magnets as I find the blade easy enough to hold in place with the use of the guide rail. Some improvements I could possibly make in the future: -Mine is mounted to a piece of wood with some holes but I realized it's hard to turn the wing nuts for the guide rail. A new guide rail that has the wingnuts on the top and hex heads on the bottom of the guide rail slot would help. -I had originally designed tool-less parts, but I opted for a more robust setup that requires an Allen wrench. It honestly wasn't much for me to keep an Allen wrench with the unit. It would be easy to maybe add some epoxied knobs for the Allen screws. You will need the following hardware: 1 x .5" Aluminum Tube (at least 5 to 6") 4 x M5x16 Cylinder/Socket Bolts (Base/Clamp for Tube) 4 x M5 Hex Nuts (Base/Clamp for Tube) 2 x M5x20 Hex Head Bolts (Guide Rail) 2 x M5 Washers (Guide Rail) 2 x M5 Wing Nuts (Guide Rail) (Optional) 10mm x 2mm Magnets Like most my files, I include the .STEP, so feel free to edit anything you need to.
