Some body asked me to make a striker here while back with an ivory tip, I can't remember who it was, but any how, I was in the shop this morning, and found a piece of Mammoth Ivory that looked good to use and a hunk of Tulip wood....I made this one 10" long, which can be cut down to 9- 1/2" long no problem. Sounds great on glass, haven't tried it on slate or ceramic though...
