Blades

While peeling apples last night, I was reminded how little force it takes to penetrate skin with a really sharp blade (cooks develop callused thumbs, and this is a good thing...no blood on the apples, just a sting.)   A friend in the SCA told me about research done to determine if someone could "accidentally" stab someone else, and the answer is a definite "Yes."    Human reflexes are too slow to pull a knife point back if either the knife-holder's arm is moving forward, or the other person is, when the first contact is made...because to a sharp point, human skin is hardly a barrier.  

The edge of a really sharp knife is just as efficient at parting skin (or lopping off fingernails...I can't count the number of times I've left my thumb that tiny distance too close to a chef's knife and removed part of my left thumbnail, sometimes including a bit more than thumbnail.  A somewhat duller knife will also do it--which is why dull kitchen knives are more dangerous than sharp ones; they can "skip" on a tough bit of what you're cutting and leap onto a finger...and again, reflexes are too slow to reverse the move.
