At the company I currently work for all private tooling is banned, except for torches and screwdrivers.
We used to use "private" toolboxes issued by the company up to three years ago.
All our maintanance vehicles are equipes with a standardised toolbox bolted to the vehicle.
the vehicles are issued, per shift, individualy and signed for.
A simillar approach is used in the hangar.
Stores has approx 40 standardised toolboxes, which are issued individually to a specific person to be used on a specific a/c
Additionally all toolboxes have a logbook which is to be signed before and after use.
And ALL tooling is etched with the number of the toolbox.
As a last "line of defence" every a/c planned for maintenance in the hangar is issued with a toolbox list, thus providing traceability of toolboxes used on a particular a/c on a given date.
This list is an integral part of the workpackage for that a/c and is filed in the same manor.
And believe it or not; tools still get lost...
