Excellent little folding file
I am a lady and carry mine in my purse, so I can't vouch for durability in a pocket, but it is an actual FILE, and not a metal 'emery board' as you get from some vendors.  An actual file will outlast an emery board, as the grit on emery boards wears off in a short time and leave you with rougher nails. Being folding, it takes up less room in your purse/pocket and is less apt to be refused by TSA.
