I've got a piece of rosewood dymonwood that's cracked and checked like krackle paint, my friend Dorris sent it to me to experiment with, so I filled it with super glue and sanded it a month ago, cracks and checks appear to be gone, might make good knife scales but not sure about a riser, who knows why it cracked and checked, or what it had been through before my friend and I got it, but it sure looks good, might try and make it a riser for a lightweight bow for my wife or daughter, but it will be thoroughly tested, and I mean thoroughly before I place it into such precious hands, this is the only piece I have ever seen do this...............Steve
