Knife Sharpener Project.

[Ken226]

This project required the use of nearly all of my machines. Except maybe the welder and air compressor.

Inspired by the wicked edge pro series.
I bought the clamp from WE, and fabricated the rest using my Birmingham 13x40 lathe, PM935 mill, and G0704 CNC build.

Drilling and facing.

It works great with edge pro Shapton stones epoxied to 3d printed mounts, but probably cost more in time and materials than just buying one.

But this one was made by you so it's value is much higher than the one you can order from someone else

I wanted to be able to sharpen using lower angles than the Wicked Edge allows. I can go down to 7° per side.

I tested it by sharpening an old butter knife at a 7° per side angle. The result was a butter knife with an edge like a scalpel. with a 10,000 grit Suhiro Rika stone, that butter knife leaves a clean, single pass shave on one-day stubble.

That is beautiful work! Looks professional and I love the engraving. I am not sure why you feel you need such a sharp knife for butter though?
