I doubt that there'll be another civilian run of Yard Guards/Hooks, although that's purely speculation on my part. I got the impression that they did didn't sell particularly well and that the (non-hook) Yard Guard model sold better than the Hooks.

I don't think that the problem was as the design as the timing -- Swamp Rat had been pushing their Mini-Mojo and Mini Uncle Mojo models for quite a while, including EH3 military overruns, immediately before the Scrap Yard Guards/Hooks were released. I think that most people who wanted a knife in that size and style already had Rats (at least that was the case for me). Eventually, I picked up one of the initial release Yard Hooks in the secondary market, and I got a Tan one at the last Knob Creek. There's no telling what you'll find at one of knife shows, but if you aren't able to make one of them (and show up early when you do, because I recall they put out less than 5 Hooks at Knob Creek on Friday -- first come, first served -- within two hours, there were almost no non-custom knives left), then I'd suggest the secondary market.
