What Work Sharp Ken Onion Edition owners say

I have the Ken Onion version. At $140, it's great and a better value than the Mk.2.

If you get one of these don’t tell anyone. I made that mistake and now sharpen all the knives for all my coworkers and family.

Of coarse nothing is compatible with the old one.

Worked great, time saver and simple to use. Would highly recommend.

I'm really pleased with this! It works like a charm

It's easy to say don't turn on the machine when you aren't left handed and have to use the entire machine backwards.
