Trekker The Victorinox Trekker, also known as the Trailmaster, is a very popular model in the 111mm series of knives. This series features a locking main blade, and an extra strong locking screwdriver / cap-lifter. The Trekker has three layers with a popular mix of tools. In 2003 the Victorinox One Handed Trekker (OHT) was introduced featuring a one-handed (OH) opening blade. The OHT is a civilian version of the original One Handed German Army Knife (OH GAK). Outside of North America this model is still known as the Trailmaster (see History).

GAK Variations
GAK Variations


  1. One Handed Trekker (OHT); This version has a main blade that can be opened with one hand. The blade is serrated rather than plain-edged as with the Trekker. Initially the opening hole was a an elliptical style, but in 2007 was redesigned to be more circular. The One-Handed version of the Trekker (OHT) has several different versions available.
  2. OH GAK;The OHT is a civilian version of the original One Handed German Army Knife (OH GAK) which replaced the 108mm German Army Knife (the GAK) in 2003 (see below). The OH GAK is near identical to the first version of the OHT, except that it has olive drab green scales with a molded in German Army Eagle, and it doesn't have the toothpick or tweezers. The OH GAK has a low-profile lock release, recent versions of the Trekker have a more prominent release which can be more uncomfortable when the knife is tightly gripped.
  3. Back Oxide Blade; The OHT was released in a limited run with a black-oxide coated blade.
  4. OHT Plain Edge; In 2007 a limited run of Plain Edged One Handed Trekkers (PE OHT) was done (date needs verification). In 2008 the plain-edged one handed opening blade was offered as a standard option.
  5. The One-Hand All Black version (0.8463.M3.3) (OHT-BO) with black-oxide coated tools, liners, springs, and keyring. Black nylon scales. This model was first produced in 2010, and was initially most widely available through a limited edition special military theme collection of 3 different tools. The knives from this set are numbered on the blade, and included the olive pouch 4.0822.4. This model has been available outside of the set infrequently in Switzerland, and in 2011 more frequently in the European markets of Italy and France. A very popular model with collectors, availability appears to be still quite limited.
  6. Victorinox 2012 Damascus Limited Edition
  7. The Black Ice Trailmaster was a 2013 Limited Special-Edition featuring special black ice coating on the tools that gives them a shimmering look. The coating is thought to be a PVD application, but the chemical composition is unknown. This model also features camouflage scales, and orange-pastic tipped tweezers that feature a laser-etched metric scale. This model is a member of the Black Ice Series that consists of 3 models including the a Spartan and a Classic SD. Production was limited to 1000, but the release is not numbered.
  8. — other variations need documenting —


Originally called the Trailmaster, it was renamed the Trekker due to the name already being in use with Cold Steel of California. Cold Steel's TrailMaster Bowie knife is one of their signature knives, and so Victorinox changed the name of their knife. The ))Trailmaster(( name can be found on some older packaging, and outside of the United States.

The OHT was released in 2003 as a civilian version of the new German Army Knife. Victorinox was awarded the exclusive contract which called for a one handed opening knife with all the features of the current 108mm version GAK. The 108mm contract was shared amongst many other manufacturers GAK Variants. After choosing the Trekker model and adapting it to a one handed design, Victorinox offered it in the civilian market, where it has proven to be very popular.

Victorinox redesigned some of their 111mm models in 2007 with new locking bars and a slightly altered opening hole on the main blade. The OHT was included in that redesign, and newer models can be identified by larger, more prominent lock releases and by an elongated circular hole with "Swiss Made" engraved on the blade.

In 2008 this knife was used as the basic design for a new Swiss Army official issue Soldier's Knife, the first new design since 1961. In the same year a Plain-Edged One Hand Opening blade was offered as a standard option on the Trekker (Model: 54875).
