I have the original version. They've actually improved it (more precise angle adjustment).Very Nice! I use the Razor Edge hones and guides developed by John Juranitch, but have been eyeing this system for some time now. Especially for my son-in-law. He didn't like my set up, so we've tried the Ken Onion Work Sharp. Even though I warned him to be careful and not create a tail on the blade, voilà, his knives have tails. This system looks almost foolproof.
