What's the oldest tool you have ?

I have two that were my dads. a pair of pliers, and a wooden handles screw driver. They date back to WW11 or the 50s.
MY dad passed in 1982 at age 78 and they lived in Ga and me in Mo. I flew down for the funeral. I was at a horse sale in Tx when he passed. I flew to Ga and friends drove my rig back to Mo. for me.
I never thought once about such as his tools when I was there, and later found that the neighbor (my age), went over and "bought" all his tools off my mother. I seriously considered driving that 1000i trip there just to attempt to whip is ***, bad.
When confronted, he said they were all just mixed in with his stuff.
