who or what company makes the best, most durable balisongs or butterfly knives? i think it would be cool for busse to make one as a prototype. i know id buy one. they could use INFI or SR101 (more preferred for this) and with the strength of that steel and its great edge retention, i think it would make for a killer addition to the busse family. but then again, they would be breaking from their traditional fixed blade stock...

any other good tough butterfly makers out there? what do they run for normally? <img src="/ubbthreads/images/graemlins/confused.gif" alt="" />
