" The answer was obvious. The useless finger ends must be cut off at once, so they could no longer get in the way and hit things. I tried tentatively to cut through the smallest finger with a new pair of secateurs, but it hurt. So I purchased a set of fretsaw blades at the village shop, put the little finger in my Black & Decker folding table’s vice and gently sawed through the dead skin and bone just above the live skin line. The moment I felt pain or spotted blood, I moved the saw further into the dead zone. I also turned the finger around several times to cut it from different sides, like sawing a log. This worked well and the little finger’s end knuckle finally dropped off after some two hours of work. Over that week I removed the other three longer fingers, one each day, and finally the thumb, which took two days. "
