I know that every one says tantos can punch through a car door and have the strongest tip in the knife world but if you rounded off the part where the blade starts to rise into a tip, wouldnt you have an equally strong tip with a more usefull blade? I doubt a tanto would be more usefull than a drop point even for a tactical-grab a sentry from behind and slit his neck-deanimation. A deeper belly would give more slicing surface than a tanto. Is there any practical purpose for tantos or is it all hype? The only thing I find them usefull for is scrapping paint off of a surface.
