This summer we were deep in the weeds, everyone moving at light speed to get us caught up. I had opened my line fridge with one hand to put some mise back, while I plated with my other hand. I used my knee to slam the door shut again. The timing between my knee and my hand was a little off, and I blasted the door shut on my fingers right at the knuckle.
Nothing serious ever came out of it, knuckles swelled up something awful for a few days, and busy season cooking wasn't the most enjoyable thing with my red sausage fingers.
On a side note: I remember the first time I ever cut myself, I was chopping veg and took most of my index fingernail and a decent amount of flesh underneath off. My chef at the time was watching me and the first thing he said when it happened was 'You're promoted!'. Bled like a pig and was super tender for a few weeks but the fingernail grew back good as new and you can barely tell anything ever happened.
