The video for the blade grinder attachment shows no guide. It shows a guy holding a knife horizontally but freehand. Doesn’t seem any better than a belt sander. I have the KO sharpener and I’m not impressed with the blade guide. It’s small and curved at the bottom. But what makes the attachment any better with no guide at all?
I’m thinking about making a little guide that screws to a workbench that goes up over top of the sharpener and holds the knife at 90 degrees for more consistency. Thoughts?
