How can you tell which one you've got? I bought my DM at Knob Creek this past Saturday at the Busse table. The receipt just says "Dumpster Mutt". It's a plain edge in desert tan. I got it for $69, it seemed like a good deal, especially considering some of the Busse knives were going for +$800.

Also, where's a good place to get a kydex sheath for it? I'd like something off the shelf, in desert tan and is similar to the ESEE/Rat Cutlery RC-4 sheath only as shown upper right here: http://eseeknives.com/rc-4%20instruction%20sheet-B.jpg

Thanks,
