I recently bought a couple of Ray Isles mortising chisels from Tools for Working Wood; and while using one of them for the first time, the handle cracked after only making 8 mortises. I contacted TFWW to try to get a replacement handle, but they immediately shipped a new chisel which arrived in two days. I thought that was great customer service. As an aside, my prior hand tooled mortises were done with a decent set of sharp bench chisels. I had to be very careful in striking the chisels (rubber mallet only) to keep from bending the tang. That is certainly not true with the mortise chisel, and it cuts the time down significantly for me. Now I only have a bout 50 more to chop for this project!
