I guess that the oldest thing we carry is a 1944 U.S. Army pick. It was designed to carry in a pack to use where an entrenching tool won't work. I bought it when my youngest was about 8 or 9 at the Famous Army/Navy Surplus Store in downtown Los Angeles. The youngest is 51 today. Her son and daughter use it when we visit rock hounding areas or just for fun.
I don't smoke but I have thought seriously about carrying my 1959 Zippo Light from the boat I served on back then.
I don't know how old our cast irons are but I'd bet from the 20's or 30's.
Too much old stuff that I would hate to have lost or damaged that reside in my wooden toolbox or in my dresser.
