Eli5: How do punches create ‘cuts’? Are they treated the same as if you’ve been cut with a knife?

Question

I was thinking specifically about boxing, so like no knuckles. Do other blunt objects cause cuts?

Answer 1

You have the bone under the muscle under the skin. If you push that soft tissue against the bone hard enough the place that gets stretched thinnest gets torn. If you have a ring or something on that’s going to cut too. You might also get an abrasion from rough surfaces. Boxing gloves can give you rub burn.

If the cut is deep/long enough you might stitch it. It’s not exactly like a knife since knifes are smooth but similar techniques.
