One possible use for tantos.... I've never used a tanto for this, so take it with a grain of salt, but I'd bet, from the shape that they'd be great for batoning.
Think about it. A drop point, if you strike along the point, is always going to deflect a little because you'd be striking at less than a 90 degree angle to the spine because of the downward curvature toward the tip. Deflection = wasted energy.
The swedge of a clip point will always dig into the baton as you strike it. That means the energy that COULD go into the downward movement of the blade is then going into chewing up the baton. Less focused energy is inefficient.
Tanto, on the other hand, offers a flat spine all the way up to the tip. You strike perpendicular to the spine at any point up to the tip, and there is no swedge to dig into the baton and waste your enegry.
Now, unlike most Becker lovers, I don't baton. I have hatchets for that, so it makes no difference to me. But I'd think, at least in theory, an American tanto ought to make a good batoning knife.
