Mine is a Brownells Magna-Tip set, with extra bits from an old B-Square set, a few random other bits (eg torx bits, which I hate with a vengeance), and a Grace 9-piece set of turnscrews.

Just looked these up on e b a y. Astonished at what they cost, especially given that these days they must be made in China.

I have a feeling that you can find the same things for much less if they are marketed as general tools, rather than special gunsmith tools. Anyone know?
