Tanto points are good for stabbing things, because the tip is strong. They are a pain to sharpen.

I prefer drop points, straight backs, and leaf shaped blades. because those are what I have always used and they just feel "right" for me. I have tried a few clip points. I found no advantage to them, and the tip looks fragile on many (I'm talking about the extreme clip points). I never broke a tip, probably because I was too afraid to use the knife hard enough to break the tip!

I do like the milder clip point style. Like the Cold Steel SRK. That almost appears to be a hybrid of clip point and drop point to my eye.

As far as the "why" I like what I like ... mostly it's just familiarity.
