I'm not STR, but I'll give your question a whack.
I have seen pictures on other sites of people's garage mods of waved byrds. It is just like the "tsunami" mod that is done on spyderco's, where you cut into the spyderhole to make a (really huge) wave. These mods are certainly going to make your blade weaker. The byrd's are built very similar to the spydercos, so the basics of waving one are about the same as waving the other. If I were to venture a guess, I might suggest that a garage-waved byrd might be a little stronger than a spyderco with the same treatment because of the lower carbon content of the steel. Bear in mind, though, that I haven't seen any good information about the behavior of the byrd steel.
