EMF,

Well, the American tanto is the one that has both cutting surfaces straight. A true Asian tanto is one that is actually a Spanto, but more angular at the tip.

The one on the Tali-whacker is an Asian inspired tanto derived from the Japanese Katana. Up swept blade with a subtle transition of grinds.

I think the whackers were an awesome overrun and I wish at that time I knew about Busse.
