I do not rust hunt often because truth be told I have too many tools and little need for others. That said I've become a fan of folding draw knifes and would like to add one to the stable. eBay had a Jennings 10" folding drawknife with a high bid of $22 USD and just a few hours to go that looked ok, not great but ok with not much pitting and the handles looked usable. I bid $25 USD and forgot about it, I just received a email from eBay that I missed out because the drawknife went for $122.50 USD. That's howling at the moon crazy.
