Yeah those cuts that look worse than they are... you know the ones... the bleeders. Super glue is awesome for those.
My best story along that vein (pun intended) is back in my late teen years I worked as a stockboy in a grocery store. Come in at 2-3 in the AM and work until noon or so.
Anyway, came in off of like zero sleep and a couple brews to unload my frozen food truck. Slam out the pallets and start stocking. Back then there were no safety blades just what was pretty much a razor held in a folded piece of metal. I opened it to cut a box and, with thumb on the back, ran it over a box to open it... didn't open. Hrm, blade must be dull... could've sworn I changed it out when I came in. Put some more force on it and run it down again... no luck.
Look down at the blade and I was holding it backwards. The brand new razor (I had changed it) was now firmly embedded in the bone of my thumb. Amazingly there was little blood until I went back to the bathroom and pried it loose. It looked like something out of a slasher flick in there by the time I had it closed up, lol.
Super glue worked wonders.
