I too can attest to "avocado hand" and I've put up pictures in the past regarding it, too.Avocado hand is a real thing lol.. now apparently is coconut hand lol
The knife I was using to 'cut around the pit' in the very beginning of the process, sliced RIGHT THROUGH the whole avocado AND pit and right into my hand requiring stitches right then and there.
Never again, will I hold one of them evil bastards in my hand to cut in half. From now on it's on the cutting board, with my fingers above/beside the blade. And yes, I sharpen my own blades.
