Welcome to the Yard, adamlau. <img src="/ubbthreads/images/graemlins/smile.gif" alt="" />
Good luck on your quest for a Yard Hook. I have to agree with Bld522 and WD, the secondary market would probably be your best bet right now. The only other option I can think of is if plan to visit one of the few shows that the Busse family sells knives at, for example the Knob Creek event. There have been some Tan Yard Hooks at both of the last two that I've been too. That's no guarantee that there'll be any at the next though.
