Well, think about it Misque. With a Wharncliffe blade, the entire sharpened edge is at the same relative angle to your hand and body depending on how you hold the knife. And if the knife is made so that the blade is canted downward at the tip it becomes even more effective for reaching out there and touching someone and leaving a very greiveous wound behind with minimal effort. The tip is especially vicious when you think about it. As a side note, the Wharncliffe blade is the best steak knife in the drawer too. The only part of the edge that contacts the plate while cutting your meat is the very tip. Very efficient.
It's also an easy edge to maintain. One of the simplest to sharpen that I've used. But, surprisingly, it's a little difficult to end up with a perfectly flat, pointed tip on a Wharncliffe every time depending on your grinding equipment. But, on the other hand, there's probably no easier blade for grinding a final bevel on. And of course the next step is a hawkbill. Now that's a nasty blade!
