Unarmed vs. Knife

Under more likely rolls, you get 3-5 injury on a cut and 2-4 on an impale, which is about manageable with a good application of First Aid at TL8.
If the knife masses less than 1.42lbs, the parry auto-fails, so there's no Knife roll to injure the slammer at all.

I should probably clarify that I did not mean that this idea does not make good sense in terms of game mechanics so much as, "Kids, do not do this at home, IRL (unless the guy with the knife is facing exactly away from you and doesn't know you're there, and/or you possess a superhuman ability to instantly calculate this kind of odds, in which case totally totally do it)."
