Reclaiming a drawknife

Jeremy Osner

>Many moons ago (IIRC it was at last year's CRAFTS auction tailgate), I bought a very pretty drawknife in atrocious condition from somebody's junk bin, thinking I would reclaim it someday. Today I made a first pass at it, with mixed results.

The tool is very light weight -- the blade is no more than 1/2" from edge to back and quite thin, and has lovely handles that look kind of like the ones on the Ashley Iles palm tools. The only way I was going to get the bevel onto the grinding wheel, would be to take off the handles, which I didn't really want to do, so I figured I would try to get the rust off the bevel with stones. I poked through my slipstones (picked up cheap at another tailgate in anticipation of the day I learn to sharpen my gouges) and found a set of 3 small rectangular stones marked Coarse India, Medium India and Fine India. (Anyone know what make the stones are? The logo on them is a bear's head.)

So I held one handle of the knife in my left hand, pressed the other handle against my chest, and went up and down the bevel scrubbing it like using a toothbrush. After a couple of passes with the coarse stone I could see metal. I did the same on the back, passed through all the grits and then I used the edge of my Arkansas stone as I have not got a slipstone.

How'd it come out? Well it is not as sharp as I'd like, though it will at least cut wood. The edge is not real even -- it was hard to pay attention to keeping the stones at the same angle, working the way I was. I think I need to figure out a way to hold the blade in a vise, and try it again.

>Jeremy, do you have a metalworking bench vise? It would make holding the drawknife a lot easier.

>Yeah I do and that's where I was thinking of holding the knife -- I'm not sure exactly how though, since the blade is so thin -- I can't put the back of the blade in the vise and still have access to the front. And also it's curved. I guess I will hold one end of the blade in the vise, sharpen the other end, then turn it around.

>Sharpening drawknives is tricky. I do it the same way as you describe. Just wear a big leather glove on the hand that holds the stone.

Otherwise, there's no magic. It may take me an hour or more to ressurect something like that. Stick with that coarse stone until you have a nice even edge.

The other thing I do is push the handle into some corner somewhere, up against a clamp on my bench maybe.

>Bob Smalser has an article on The Drawkife over in WC articles that was helpful for me. Also I was able to use a file on my Pexto drawknife to shape a new bevel. Then I went to a course diamond stone and then to oil stones. I also held it as you described. Now that it's in shape, I am anxious to set up some stones ala the Smalser way.

>Hmmm..... I have an old Witherby. It is so hard a file won't even touch the edge. I clamp one handle in a vise with wooden jaws, bevel up, and the rest of the drawknife hanging out past the end of the bench, and work it with a diamond stone, followed by Arkansas stones. It still seems to take forever to reshape the bevel by hand. It is incredibly hard steel.

If I had one like Todd's, I would use a belt sander for rough shaping, but if yours is a small drawknife, about the only kind of sander that would work would be one of those with the long, 1" wide belt. Of course, one of those huge treadle powered sandstone wheels, with the water bath, would work just about perfectly. We were discussing them a couple of days ago.
