I usually don't sell things.
Just throw them away when they are toast.
Guns? - No problem. I'd sell my 1911 tomorrow. No special bond.
Knives? Keep them for a lifetime - or until they break.
My wife would agree that I have a hard time throwing out old shoes.
I tend to were them with holes in the sides and hole in the soles.
The Wife used to be an "everyday" item wen we were younger
But , That train has long left the station ...
