FYI
Spotted this on a recent visit to Axminster
This has a shoulder strap, thus avoiding the problems.
I bought one to hold my basic electrical stuff. Enough room for a multi meter, pliers, cutters, strippers, screwdrivers etc and everything's handy when working on a ladder/step up.
Well made & fairly cheap, it would hold a small/medium drill driver although not designed to do so.
