The "Americanized" tanto's only good point...is the point... The point is reinforced, making it a better blade if you want a "sharpened crowbar". For EDC a clippoint, spearpoint, droppoint, wharncliffe(sp?), and many other blade styles would do alot better. They give more belly and pointier tips. Which is what a knife is for...(Except the wharncliffe.)
The reason you see them availible as a seconed bladestyle is because many non-knife people think they look cooler. (Actually there are some knife-nuts here who love them, but the majority would disagree.)
Hope that helps Goat.
