When I was around 8, a neighborhood kid was swinging around a light pole, just a plain metal pole but it had the wirenut box attached to the side about a foot from the ground, which he was standing on while spinning.
His foot slipped, the corner of this box ripped his ankle open, cut right up from the top of the shoe about 6 inches into his lower calf/ankle.
He screamed and ran home, blood pouring everywhere. Saw him a few days later with massive stitches and bruising all over his leg. Wasn’t as bad as it looked, but fuck me it still makes me wince thinking of my ankle being sliced by a dull metal corner by weight and gravity alone.
About 3 years ago, I was looking for emeralds at a closed emerald mine when I had the brilliant idea of hitting a random rock with my pickaxe. Turns out the rock was harder than the pickaxe, so a piece of the metal broke off and flew into my finger. I was 10s of hours away from any hospitals, and the metal curved around the bone of my finger, so I had to take my dad’s camping knife and cut the thing out. This was at a camping spot, so I had running water, but it wasn’t easy.
