Shiro Kashi

Also called Japanese White Oak (which is not the same as the inferior American White Oak) this wood is hard, dense, long grained, resists splintering, and has excellent impact resistance. It is traditionally used to make contact-grade weapons. It is an excellent choice (along with weapon grade Hickory) for use in Jo, Bo, Hanbo, Tambo, and Bokken weapons.
