I did this to myself in november, changing my track bar. Had my hand inside the wheel well turning a wrench with an extension and slipped, scraped it on plastic. Wasn't even super painful or deep but it was wide and ragged and it's still visible.
ITT: Wrenching fuck-ups
I really still have a problem visualizing it. Like, this is Veeky Forums we've used sawzalls. I'm imagining cutting someone's fingers off on purpose with one and even that would be hard to do. You must have literally landed with one hand pulling the trigger and the whole thing rotated perfectly blade up and your other hand landing directly on the blade with all your weight.
