I have a few shovels and hard tine rakes with broken handles and noticed a replacement handle is more expensive than a shovel.
I have a post hole digger and a sharpshooter that have 1.25" 16ga steel tubing handles so I don't throw the tools away but I am sure a lot end up in landfills.
So what's behind the cost, lower demand for handles due to cheap throwaway tools?
Yours may be, but I skulk about at swap meets and garage sales looking for old English made shovels and then re-haft them with good oiled hickory handles.
And God help any sob that dares to look cross-eyed at any of my tools.
