Just wanted to say you guys have rekindled my love of knives. I have a pretty good collection in my safe but was getting just a little bored with the whole thing. I had no balis in my collection so after reading a few of the posts here I decided what the hell and bought a BM42s- Swinging these things is like crack, the more you do it the more you want do it. I cant seem to put the damn thing down. There is just something theraputic (sp?) about the whole thing. I mean, what could be more fun than swinging a razor around as fast as you can? Anyhow I have rambled on enough but I gotta know just one thing, is the Tachyon worth it? (gotta have at least two or the BM42 will get lonely)
