you should fit some drawers under that workbench. then, all the tools lying on the workbench could go in the drawers.
lots of free space ON the workbench after that. and it's an easy "upgrade"
Ah no, there are plenty of storage spaces for the tools elsewhere. Several filing cabinets nearby. And under the bench is used for boxes of stuff that is best stored there (and nowhere else to put them.) My mech workshop is severely space constrained - it's a small single car garage.
Anyway, while I'm working on something, I find it easiest to let hand tools pile up close by. When a project gets finished I tidy them all away, then start again on the mess.
The bench working space is minimal atm, because there really are at least two other unfinished projects 'underneath' the mess. No wait, *three* other projects. So it didn't have a clean up for a while.
