as you have already found...horn is VERY hard. I was shocked the first time I tried to work a piece of it. It polishes and sands just like very hard wood. I use files to put the grooves in, small needle file. If it was me I would sand both stock and plate flat on a sander and fit from there. Horn is much stronger than plastic, yet like anything organic, it has flaws. Good luck,
