Electric kit bag/tool contents

I just had a thought about a small selection of tools/kit for doing electric firing.

Just wondering what parts, so far I’ve listed

Multimeter
Pliers
Side cutters
Screwdrivers (multi bit set thing)
Gaffa tape
Cable ties
Igniters

Anything else that could be needed for in the field for when a system has an error, fault needs working.

Cheers
