As a little bit of history, "reverse tanto" is a recent, and, in my opinion, completely unnecessary addition to blade-shape terminology. If you look back to classic pocketknife blade shapes, their names covered all the possible variations of the point styles pretty thoroughly. In fact, the article RamZar cited on Knife Depot's blog acknowledged the subtle, but well established, differences between Wharncliffe, sheepfoot, lambfoot, coping, etc.
Before Bob Lum's custom-made tantos, a tanto was only the traditional Japanese expression of that style, which had a curved edge near the point and had to have a tsuba (disk-shaped guard, like a katana). Without a tsuba, that same style of knife would properly be called an aikuchi. Bob Lum was the first to put a faceted katana-style kissaki (point) on his modern interpretation of the tanto. Cold Steel took Lum's idea and ran with it to create their now iconic modern tanto.
Now, most people think an "Americanized tanto," as it's sometimes called, is what a tanto is supposed to be and the understanding of the real history behind it is fading. While "reverse tanto" sounds cooler than "lambfoot" or "coping," in reality, that blade shape already had a name. We just need to look deep enough into well-established knife history to identify it.
I don't mean to sound like a crusty old guy, but knives have a deep history and tradition. While I am all for innovation and I do not believe that "everything has already been done," ignoring established history is not innovation. If someone points to the letter "W" and calls it a "reverse M," they haven't invented anything...
