Zero Tolerance 0620CF Tanto Knife Carbon Fiber (3.6" Satin) ZT Emerson (from Todd's original post). It would be relatively easy to sharpen out the Tanto and make it into a more conventional blade shape. I have done this to a couple blades.

AND don't forget the Reissued Tali-Whacker LOOKED like a Tanto but isn't. Just the way it photographed.
