I was digging through a pail or rusty tools the other day at a yard sale and found a pair of early Channellock pliers. Classic design, I can spot them a mile away. Bought the pair for $1 and brought them home to clean up. First one was just what I expected, Champion DeArment Channellock #410 with an early patent date. The second one had a bit more rust but I was confident I could save it. Vinegar soak, wire brush, oil and wipe down, looks great! But... wait a minute... something's not right here.
