The Victorinox Climber with Long File Swiss Army knife is a rare, retired variation of the Climber knife, which includes a long file on the back. This pocket knife is also sometimes called the Model 3722 knife.

This model is definitely a rare, collectible knife that sells at a very premium price. If you just want a practical pocket knife with a file, consider a Trail Guide or a Mountaineer.
