I have one very rare knife. It is an older NIB COLD STEEL "Desperado" made with AUS-8 blade steel. They have not been made with that steel for quite a while. The AUS-8 is very superior to the 420 that they use now. This knife has been out of production for some time. The factory number is #49DS. My contact info is joedot@swbell.net I only want either Spydercos or some Benchmades to trade for it. thank you
