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).
The Trekker comes with Nylon scales which are usually black (liner-lock version). Camo, and Camo +ARMEE scales are also available.
An earlier version, probably marketed as the Trailmaster, had red nylon scales with a slide lock.
- One Handed Trekker (OHT): This version has a main blade that can be opened with one hand, and is the civilian version of the OH GAK (see below). The blade is serrated, rather than plain-edged, as with the original Trekker. Initially the opening hole was an elliptical style, but in 2007 was redesigned to be more circular. The OHT has several different versions available, recent versions have a more prominent release which can be more uncomfortable when the knife is tightly gripped.
- The One Handed German Army Knife (OH GAK) is nearly identical to the first version of the OHT, except that it has olive drab green scales, with a German Army Eagle moulded into the scales. It doesn’t have the toothpick or tweezers. The OH GAK has a low-profile lock release. This knife replaced the original 108mm GAK in 2003 (see History below).
- Black Oxide Blade: The OHT was released in a limited run with a black-oxide coated blade.
- OHT Plain Edge: In 2007 a limited run of Plain Edged One Handed Trekkers (PE OHT) was released (date needs verification). In 2008 the plain-edged one handed opening blade was offered as a standard option.
- The One-Hand Trekker - All Black version (0.8463.M3.3) (OHT-BO) was first produced in 2010. It had black-oxide coated tools, liners, springs, and keyring and black nylon scales. This model was initially available through a military themed limited edition collection of 3 different SAKs. The knives from this set are numbered on the blade, and included the olive pouch 4.0822.4. This model has been occasionally available outside of the set in Switzerland, and was also available in Italy and France in 2011. A very popular model with collectors, availability appears to be quite limited.
- Victorinox 2012 Damascus Limited Edition
- 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-plastic tipped tweezers that feature a laser-etched metric scale. This model is a member of the Black Ice Series that consisted of 3 models - including a Spartan and a Classic SD. Production was limited to 1000, but the release was not numbered.

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.
Victorinox was awarded an exclusive contract by the German military to manufacture a one handed opening knife, which contained all the features of the 108mm GAK, as a replacement for that knife (many manufacturers had made the 108mm GAK). Victorinox selected the Trekker model and adapted it to a one handed design. In 2003 Victorinox offered a civilian version of this knife to the general public, 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 and Swiss Made engraved on the blade.
In 2008 this knife was used as the basic design for a new military issue Soldier’s Knife to the Swiss Army. This was the first redesign of the Soldier since 1961.
In the same year a Plain-Edged One Hand Opening blade was offered as a standard option on the Trekker (Model: 54875).
