Recently there were two knives by Bob being offered on Ebay. One was a Large Field Grade Tanto with an original Lum kydex sheath being sold by a seller in Japan. It sold for $986 + $20 for shipping.
The other was a "major score" in knife collecting lingo. It was an used Folding Tanto with Black Micarta. There was a small chip in the left micarta scale towards the front of the bolster, aside from that, it's in very excellent condition. Best part, sold for $400 + $10.00 shipping.
