I've had a swisscard for nearly as long. They're pretty pointless, because anywhere you could carry a swisscard you could carry a utillikey or one of those toolsteel cards with the useful shapes punched out of it, and anywhere you're not constrained to something that fits in your keychain/wallet you can have a full-sized knife or gerber instead. So it's not worn out because it's not really been used for anything. You can buy replacement pens/toothpicks/tweezers, and it'll hold any standard sewing pin. I would definitely recommend the utillikey over the swisscard, despite how *exciting* it makes using every tool that isn't the knife.
