SK Wayne ratchet and socket set purchased in 1968 when I was 16 years old to make a $300 ‘65 Corvair that I towed home drivable. It’s been abused with cheater bars and the only casualty was a ‘14mm socket that was replaced under warranty.
Pair of channel lock pliers I found in the backyard of a house I moved into in 1991. Cleaned the rust off and they are still in my tool bag today.What is the oldest tool in your collection that you regularly use? Not just old tools you own, but the one(s) you actually use? Mine would be the Giller USA adjustable wrench that was my Dad's that is most likely from his time in the Army during the mid-1960s. I don't think I have anything older.
