Work Sharp

[brutal]

I have one, and it works well on thinner blades, but if it is something thicker like a BK2 it is marginal

I just got mine in the mail today. I already tested it on my SOG. I agree with the suggestion that it's more suited for thinner blades. You could probably modify the guide if you had to. I like it.

^ some of the videos I watched showed freehand without the guide on some of the thicker blades.

I could be wrong, but perhaps the Ken Onion model (adjustable) guides are wider?

I don't recall having any issue with any of the thicker blades - BK2 or Gerber LMF.
