The Victorinox One-Hand Nomad Swiss Army knife is a large, 111mm / 4 1/4" Swiss Army knife with a one-hand opening blade. The large blade locks open, and is released by pushing a liner lock that is positioned parallel to the blade. This model was introduced circa 2010, and was retired a few years later. It was also known as the Side Chef.
There are no similar Wenger or Leatherman knives.
