I am not fan of what I have heard some Japanese blade students call the "American Tanto", the knife with a squared-off, chisel style point that is not quite at a ninety degree angle to the cutting edge. (I have seen several Japanese tantos, both antique and new, with a flat back to the blade and the edge curving up to meet the back at the point in a more or less , traditional knife manner. Ther is, obviously, distal taper to the blade as it nears the point.) Supposedly, the angled point was developed in order to pierce armor, but I can see where it could easily be used as severtecher suggests. I had not seen the American Tanto in that light before. Interesting.
