I have a few of the exact same knife. They were called "Mini Tiger Paws" on eBay. I got three of them for just under $5 shipped from China. Let me hasten to add that I already have five of the real things and the real thing has been discontinued so I felt okay trying the knockoffs. They came with no real edge to speak of and I have not as of yet tried to sharpen one.

Really, the knockoffs show just how much value you get with the real thing. My Ritter/CRKT RSK Mk5s came properly sharpened and with a very good scabbard/sheath. The knockoff comes in a vinyl/pleather sheath that's pretty crappy.

Of course, some folks that don't know how things are brought to market will buy based on price and think they have real survival gear.
