As far as the Mayhem specs go: Here is a post from a thread I started on my Damascus Mayhem in the custom knives picture gallery: " Overall length is approx. 11.5 " , Handle is approx. 6 7/8 " long, Tanto Blade cutting edge approx 4.5". For a long knife in hand, it seems very light, like 4-5 oz, but mine weighs in at 6.85 oz. though. This thing flies out hard! You get what you pay for. "
