Does anyone know where I can get information on making/buying one? I figured a wooden Tinbe would suffice, though I would rather buy it for quality reasons. The Rochin seems simple enough to make though. Thanks guys!

I don't see how to order it.

You have to call or email them. There is a link to the right for 'contact us' or something similar

Did you find one?

Yeah they want more than I would like to pay. I think I can make one that is good enough for what I want though. Thanks!

If you just intend to practice kata than a self crafted one should suffice. However, if you intend to do any kumite, I would recommend paying the money for one which is designed to withstand the rigors. Speaking from experience of using a home crafted one to do so.
