Hello all. I was doing some bojutsu training (shadowbox-style and on a tall stump in our back yard) and accidentally splintered (not a full break, but cracked) the bo with a strike that I didn't think was very hard. So the question, as I bought that bo for a group demonstration and bo kata competition (I got 3rd with "twelve winds") I was wondering if it was simply a lower quality material than it should be for striking practice. I patched it up with athletic tape and it has held well enough to not wobble, but I want to but a new bo and thought you folk might know what material to get. Thanks all.
