Hi all. I have a Crabtree and Evelyn brush by Edwin Jagger. It has a huge chunk out of it where it was dropped. I want to take the hair out of the broken handle and put it in a new lathe turned cherry handle. Any advice on how to get the knot out of the handle? I took a reciprocating saw blade by hand and cut a line straight line from bottom to top on each side hoping it would just split apart, but instead it just flaked off chunks. Thanks in advance!
