Oak is pretty plain from a conventional stock figure point of veiw but I suppose it would work.. There are sooooooooo many beautiful hard dense woods to work with why would you want to use OAK?? Get some catalogs from custom wood turning and woodworker supply houses. They often show a variety of tropical hardwoods and other wood from around the world.. But if you wish, oak should work. It splits fairly easily, is quite porous and usually has little figure. The first won't be a problem if the grips are thick enough, the pores can be sealed, and the thickness of the growth rings can be interesting....... Check those woodworking, wood turner supply houses. They stock beautiful burl, fiddleback and contrasting grain wood for little money..then have fun..
