Finish grinding mistake.

[Bob Duguay]

Received my knives back from Pete’s last week. Look good and straight. So today I have been finish grinding bevels on a couple of FFG blades. First one came out pretty good. The second looked good as well but plung line went to high and deep at the top. How you go about fixing that without thinning the whole tang?
I know one thing I have to get a better method of drilling pin holes. I ended up having one of the three holes a hair off on both knives.
Thanks for your help.

Aside from thinning the tang, making it a double edge, or getting really creative with file work (or rather a carbide burr), I don’t think there’s much you can do. As for any tang holes that are slightly off, just use a carbide burr or drill bit to embiggen the hole that’s off, and then put it exactly where you want it on the scale. The other holes will keep things lined up, and a larger hole in the tang will get covered by the scale. Problem solved.

Have to get some carbide burrs for sure.

I think a lot of us intentionally make our pin holes larger than needed. Both to ease the fit up and to allow a bit more epoxy to get into the joint and make it stronger. The way I look at it is that if the pins fit perfectly with no slop, then you have 2 separate scales, one epoxied to each side of the tang, whereas with larger pins and epoxy that mixes from both sides of the tang, you are basically making a one piece handle.
