I remember my first pair of tongs. Due to the only material I had at hand and to the fact that I knew nothing about different steels at the time, I constructed them out of re-bar. I must have spent 8 hours trying to get the two halves to conform. Punching the holes and constructing a usable rivet was another issue. After much frustration and a lot of four letter words, I finished them...and they seemed to be working pretty well. I was kind of proud of myself. The next day after quenching a project I was holding them with, they cracked and broke in three places around the jaws. :(
