I have a number of tantos. I didn't intend to have a lot of them, it just happened. I find that I like an EDC tanto with a lot of slope to the point because I like a keen point. One of my nicest looking tantos is this Spyderco Lum fixed blade. I don't know if I've ever seen a real Japanese tanto but this one looks to me like what I would expect a Japanese tanto to look like. It has a little curve in the cutting edge, a gradual transition to the point, and a somewhat keen point.
One of my favorite EDC's s this Benchmade 760. It doesn't have a real keen point and barely meets my criteria.
As for strength of the tanto blade- some tanto blades reach full blade thickness very close to the tip so it is easy to see how these tips can be pretty strong. But if you compare the 2 blades in this photo you can see that a spear point can be ground this way too.
Something that I do like about tantos is that the grind angles have an easy way of working out. There are 2 flat segments that meet the edge and the edge can be the desired thickness all the way down. Look at lots of hollow ground knives and you'll see that some have a hollow grind in one orientation, so where the curved edge meets the curve of the grind the thickness of the edge will vary. Lots of factory knives are like this and they tend to have thick edges at the point and are frequently ground at a steeper angle near the point. Look at the photo of this Vallotton and you can see how tanto-style grinds were incorporated on a curved blade to achieve a stronger point.
