Was asked about a strap wrench for someone opening bottles. I had a Harbor Freight hammer with a loose head, truly an accident waiting to happen. Some Sugru (mouldable rubber) and a short piece of rubber belt.
Sugru is great stuff every toolbox should have some.
Hacked a slot wide enough for twice the thickness of the belt. Pinned it in place with a finish nail through a pre-drilled hole. Cut the nail flush with a dremel.
I don’t have a photo of it but the area where the nail and slot are visible was covered by a piece of red shrink tubing.
