Baron given the small areas and contours you need to work around I'm wondering if one of those head shavers would work. I'm thinking about those things that have finger holes and you hold using a few fingers only. I've never used one so don't know it's width though. Have you checked one of those out yet?

I found a pile of 4/8 and a few of them will easily become 3/8 after I hone out the chips (part of fleabay lots that went right into the "needs work" bin). Even if you get one right away, I still want to try to make a blade that's 3/8 and a tad under an inch long, so I'll have at least one headed your way in a week or two. I'll PM for your address then.
