Sometimes a Tool Roll is a better option to the Tool Box. For example, tools that are on transport, motor cycle, bicycle, aeroplane. These more specialised sets of tools are best kept snug, preventing them from bouncing about. Pouches are easily tailored to properly fit each tool and a variety of materials such as leather, vinyl and canvas can be used.
Here is a Vinyl Tool Pouch Ive just completed for a motorcycle. It also has a small pouch for Allen keys and test lamp.
