It took about two months of every-day use, on a key chain with two other keys, before the Phillips head burrowed a hole into my jeans pocket, so I went back to Victorianox's pocket-friendly Swiss Army Classic.
The size and shape are nice and discreet. The metal is high quality for the cost and it's sturdy. The blade is very good, the handle system is very well designed and it locks open; the serrated edge is excellent for rope; the plain edge is a simple, one-sided bevel that's sharp, sturdy and holds a good edge. The screwdrivers work, but the slotted (flathead) ones cannot generate much torque since the blade is part of the handle (the Phillips is less tricky); overall they are sufficient for house/office work, but insufficient for locknuts or rust. The bottle opener works well (a can/ bottle opening combo would be much more useful in the same space). The locking mechanism was so stiff that it was inconvenient to open for about the first month - which meant that I didn't use it as much as I would have liked, but there were no fears of accidental opening. If I didn't mind patching pockets, I'd still use it; it never damaged anything else in my pockets - it's just like another key.
