Love the original file!

I remixed this to add a Hex on the "handle" of the screwdriver to be used with a spanner or adjustable wrench for hard to reach places.

I can see this coming in handy in very hard to reach and limited space application like the other day when i was working on my well and needed to re wire the pressure switch. The pressure tank was in the way of me using even my stubby screwdriver to unscrew the wires from the switch. If you can get this even stubbier screwdriver in there you can use an adjustable wrench or spanner then it would make a lot of jobs much easier. Especially working on cars with the tiny torx bits!

Maybe save someone a head ache!
