Picked this up recently, and while the Torx heads find no use with my C&V rides, it's a nice compact, well-built folding tool:

I got mine for about half retail new, or likely wouldn't have been able to justify the expense.

Phillips and flat head both come in handy at times. 65mm long and 135g. All metal.
