I'll throw an unimaginative idea into the ring; a dumpster mutt blade in either SR77 or SR-101, but with an extended tang for a full-sized Res-C handle, and make that handle orange so that it'll be easy to find if dropped (perhaps even orange coat the blade, but that may be too over the top).
Great idea, I love plenty of room on the handle. <img src="/ubbthreads/images/graemlins/thumbup.gif" alt="" />
