The Victorinox Parachutist Swiss Army knife is designed for parachute jumpers.

It's an all-purpose large knife with a locking blade and a versatile belt cutter-- a combination that you might find useful, even if you aren't concerned about cutting away your parachute lines in an emergency.

The Parachutist was retired by Victorinox in 2009. It is sometimes called the Rescuer knife.
