I have found a very useful little tool for carving neck heels. In the past I have used various things for this operation, including rasps, chisels, drawknives, and knives. I wanted something that would easily carve around the curve of the heel, and to which you could apply enough controlled force to cut through the end-grain. A drawknife worked somewhat as two handles allowed the use of some force with control. However the drawknife I have is big enough that it did not ‘turn the corner’ well.
I found this little drawknife that is thin, narrow, and slightly flexible. The narrow blade allows it to easily ‘turn the corner’ and the curved blade, flexibility, and of course two handles give a great deal of control. Really nice for heel carving.
