I bought this at the Indy 1500 Gun and Knife show in Indianapolis, IN on Jan. 15, 2017 not knowing there were counterfeits out there. I paid $5 for two. It has no serial number and came in a clear package.
This is a large show and the next one is in March.
I knew nothing of these knives and bought two on as a spur-of-the-moment purchase.
