This is a traditional tanto blade:

And this is what people like to call a tanto:

The first one is about as useful as any other field knife - and is really similar to many Scandinavian knife grinds. It is known as a straight back blade tip, and they all have similar tip strength.
The second one is an American invention.
I have found the that the American style tanto blades can be useful for lots of things if they have a rounded corner - especially for carving a depression in wood. But the sharp cornered kind is like having a knife with two tips: I would expect penetration to be worse - but slashing might be better because of the second tip.

The second one being an American invention is a myth, this shape, though probably not called a tanto, is documented on blades from many, many years ago. I think the "Americanized tanto" is an American marketing invention, but nothing more.
Check out the top image in this link, it can't get any more Cold Steel Americanized tanto that that: http://www.japaneseswordindex.com/sugata/shape.htm
Have you ever seen a Kamasu-kissaki on a tanto? I have only seen them on swords.No, it's a traditional Japanese design too. The Japanese Tanto you posted has an ikubi-kissaki. The "American style" is a kamasu-kissaki. They had all kinds of tip designs, here's a pic of a chart with some. (There are lots more)

I don't believe they used the hollow grind.
I sincerely doubt that any blade shape we think of as modern wasn't done at some point in the past. My point is that a typical Japanese tanto has none of the characteristics of what we call a "tanto grind" in the US.
If all those modern tantos with their hollow grinds were actually directly inspired by 9th century long swords - I'd be awfully surprised. Bob Lum's tanto blades don't look anything like that, and Cold Steel's look only a little more along those lines. The completely flat ground, pointed transition blades came after and was inspired by those.
Here's a typical Bob Lum blade profile. Hollow ground belly, convex curved tip.

Here's the original Cold Steel tanto grind - hollow with flat tip and curved edge transition:

And then there's this:

Those three are effectively very different in how they would cut, and you would have a hard time finding a Japanese tanto that is ground like any of them. The majority of Japanese tantos actually have long, tapered tips ideal for stabbing. Like this:

Looks more like that CRKT Hissatsu thing than a Cold Steel.
All I meant by "American" is Bob Lum and Cold Steel may have been inspired by real tantos, but they created new grinds based very loosely on them. And those new grinds have inspired other grinds that are even more different from a Japanese tanto. What we have today are a bunch of different shapes that have very little to do with each other or the Japanese knife they take their name from.
The curved Lum and Japanese styles don't even match our conception of what a "Tanto point" is and would be classified as "Straight back".
Have you ever seen a Kamasu-kissaki on a tanto? I have only seen them on swords.
I have several of those books. I realize it was used on swords - I've just never seen it on tanto knives.
Doesn't mean it never was. I just think the term "tanto" for a grind type has recently evolved out of meaningfulness.
They used all kinds of tip designs on all sizes of sword. A tanto is a short sword.
