Re: Long way around the barn!
I always take with me some superglue, that I use to patch small cuts in my fingers*
One day way back I was installing some wiring in my dad's house. Lacking stripping pliers I resorted to using a Stanley knife to take off the isolation; press down wire onto cutting edge with thumb, roll it around a bit. With the blade rather dull one needed quite a bit of force to cut through the isolation.
Then came the moment I got to look at the inside of my thumb, as someone had put a new blade in. It was a nice clean, almost surgical cut, with almost no bleeding. So I held it closed, grabbed the superglue, put a drop or two over the incision, added a sticking plaster to keep out the dirt and went on working. It healed without a problem, although the misalignment in the fingerprint is still visible after forty years.
