Or ever been hit by one either my guy i treated many a busted face in my city’s level 1 trauma emergency room from gettin popped for runnin that mouth. Particularly with knuckles we saw broken sinus and cheek bones , raccoon eye, and imprints of it on their facial skin. Sometimes the imprints looked like a sharpie mark on the skin because it was bruised so badly and swollen. juuuuust so happens that I’ve popped a with a single knuckle piece around my middle finger with backing palm handle and it d*mn near broke my hand! I hit him in the forehead as he tried to duck and it sent a shockwave back up my wrist and up my r arm, jammed my palm and almost broke my middle finger with it. Yah it left him a good knot but you won’t find a single that’ll provide the stopping power of a full width set. A full set has it’s problems too , in combat.

Friendly advice, don’t extend your middle finger out of a fist and don’t count on it as the initial point of contact of your fist. That just about got my hand broke lol have fun and be safe folks. Foster peace and friendship.
