Which multi-tool for keychain?

P4 or small SAK

If you can find one, a Wenger Microlite Esquire or Victorinox manager should do the trick just fine

I have carried a P4 on my work keys for a couple years now and it is a very handy little tool. Those little pliers have been worth their weight in gold a few times.
