Here's an endlessly cheap solution to carrying screwdrivers and screws when you're up steps or ladders.
You can modify a collection of these in different ways for different tools.
A plastic bottle
A bandsaw, ideally, but strong scissors will do
A drill or something to pierce holes
Cut an opening in the side of the bottle as shown. You can mark this first with a felt pen if you are unsure of the position.
Screws go in the base and one or two screwdrivers go in the holes in the top and project into the handle to keep them steady. You could even tie the handles to the bottle handle if you are working in an area where you wouldn't want to drop them, over a pigsty for example.
