The Victorinox Climber/Traveller Swiss Army knife is a retired, standard sized 91mm / 3 1/2" Swiss Army knife, that was a variation of the modern Climber model, back when Victorinox first added key rings to some knives. The Traveller had the same tools as the Climber, but no key ring. It is very different from the modern Traveller, which is basically a Climber plus electronics.
