I’m probably the last person to ask about this. I don’t use as many small tools in a week as most folk here use their Swiss Army Knives in half a day.
However:
I have one screwdriver from the Yellow and Black Tat Range that serves nearly every job that I do. It’s a four way tool. Medium and large Phillips and medium and large(ish) slot (flat). It is almost invariably left as a large Phillips.
But:
Prompted by
@TeeDee ’s subsidiary question a few posts back, my two brain cells are racing around my head like a game of Atari Pong. I’ve been considering this question of bits and shall be interested in what people say.
Why?:
I am attempting to build a shirt pocket clip screwdriver plus bits, to the dimensions of a pencil. I’ve no idea why!
And:
I’m stuck. Of the small tools that I rarely use, the screwdriver is by far the one I use most. I don’t care whether I pick up a variable screwdriver or a screwdriver proper.
I certainly don’t carry one about with me.
But what jobs? Mainly electrical or toy mending.
So:
Small, medium and large Phillips.
Electrical size slot (flat)
A torex (10). because it fits the grub screw on my old B&D router - but I keep one of those with the tool.
Maybe a 4mm Allen Key (Hex). An amazing number of items are held together with a 4mm socket screw/bolt.
Definitely not any of the sockets. If I’m undoing a nut then I’ll be close to a tool kit.
The eventual pencil screwdriver will hold four, maybe five bits with an extension socket so I’ll be interested in what this thread throws up.
One that they don’t make and now never will - The B&D Chuck Key!
Teedee has asked for ten.
