I hold the hide fur side down on my lap or on a table top. I anchor it with the heel of my left hand and hold a very sharp razor blade in the same hand. With my right hand I put gentle tension on the skin, pulling away from my left. I cut in the direction I want- with the hair or against for cross-cut. The secret is to hold the area you're cutting off the table, otherwise the hair will be caught underneath the blade and will get cut along with the hide. You'll always have a little hair get cut, but run the strip through your fingers a couple of times, and it will come out fine. And obviously, a sharper razor works better than a dull one. Rabbit skin is very soft and thin, and a sharp blade goes through it like butter, and leaves you a nice, clean edge. A duller blade is more difficult to use, and can leave a jagged, less presentable edge.
Actually, I don't go that extreme. But I do buy whole hides since I use alot of a couple colors. But don't do the multiple strips at once. Plus, I don't use crosscut, I only use zonkers, even for palmering. So what I do is stretch the hide in a rack (just a simple wooden rack that clamps on the hide) and draw out the strips. Then use a razor and start cutting. Pretty fast when you're used to it. But easier with zonkers. You're cutting with the hair flow, so not cutting into the hair at all, or not enough to worry about.
This is timely info for me on cutting rabbit hides. Just found a local source of inexpensive hides. I too made a little jig that holds 8 evenly spaced razor blades and by stretching the hide can wip out lots of nice uniform strips in a hurry. My challenge now is dying. I can get black or white hides. I've tried some Rit dyes with moderate success on the white strips. Any suggestions out there on where to get better selection of dye colors and types of dyes to use?
i've heard that kool aid works great. go to fishbc.com then go to the forum and do a search for kool aid and you will find it. unlimited colors that way as you can mix your own and it reportedly works great.
