I was all proud of myself this weekend for a) finding my Swiss Army knife and b) restoring it to smooth working order by lubricating it with 3-in-1. I aired it out for several days in an attempt to get rid of the oil smell, but it did not work, so I took it to work, cut up an apple with it and ate the apple. I also ate some 3-in-1 residue. It doesn't taste very good. On the plus side, I must have licked all the residue off because my jackknife no longer smells like lube.
