I find the tanto point useful for many things besides combat.Every time I hear something about multitools for self defence, I think of the time my sister's friend saw my XLT, and said "That's stupid, the best you could do is throw it at someone."
Recently I've come to favor a Wharnecliffe blade for a number of reasons. The knife on the Gerber Diesel is a good example. (except that I do not care for the serrations on it.)
