Spyderco Q's

This is PE version of the spyder blade. Also with a blue handle. Made for the Rocky Mountain Blade Collector RMBC in Co. I believe that Eric Glesser may have been in this organization. There is a letter that accompanied each knife. The identifing feature of these is the organization and x of 75 is laser engraved on each knife. I believe that 75 of these were made.
