Knob Creek may be a good time to try for a ScrapMuk. I understand lots of older knives turn up there.
They sometimes do, but surprisingly, no Muks made it to either of the 2010 shows. A few MPLEs came in the spring and even fewer BDLEs in the Fall, and I recall that there were a couple Scrapper 5s in INFI at both, but no Muks.
