Back when I was doing capoeira, one of the guys made a couple of berimbaus (musical bows) by hand-laminating the wood staves. They were gorgeous things, and they worked well under tension. But one did snap spectacularly. The glue failed, and the whole thing split.
The problem with a laminated staff is that its strength depends more on your skill in laminating. And unlike the berimbau above, the forces warping a fighting staff are going to be coming from all over the place, not just one direction.
Conversely, if you're good a gluing, it's probably a bit easier to get thin strips that are straight grained, so if all you can find is crap staves, it is an option.
Best,

Modern adhesives I know are impressive. But I suppose if laminates where that good...then more people would be using it. |
