This may seem a bit silly, but curiosity is killing me.

I watch a whole lot of "real life" crime shows, and I've noticed something about what happens when a bad guy kills someone with a knife. It seems they almost always end up cutting their hand when they stab their victims, and very often an extremely bad cut down to bone.

Usually the attacker is just some scumbag with a knife, not a trained expert.

It seems that the blood is part of the problem, and acts as a lubricant causing a lot of havoc for the attacker, resulting in injuries.

How, as an expert do you avoid this?
