The large, locking-blade Swiss Army knives have a hefty locking blade, for safer operation. They frequently include oversized tools, housed in a rugged body with tough nylon or polymer scales. All of these models are currently retired, and many are becoming collectors items.
The first series of Wenger lock-blade knives were listed as 120mm, but were actually about 125mm (5") long, with a 100mm (4") locking blade. The blade is released with a thumb slider on the rear. This series was introduced in the early 1990s, and retired in 2007.
In 2007, Wenger released the slightly larger Ranger series of locking blade knives, initially called NewRangers. The Ranger blade is released by pushing on the Swiss cross insignia. The body of the Ranger series knives is actually about 127mm long (not counting the heftier key ring mount), which is very similar to the original series. All Wenger Ranger models are now retired, but a few are still available in the Victorinx Delémont series, built from a combination of Victorinox and Wenger parts.
