Top left is a Jumpmaster. This model usually has black nylon scales, but this one is red which is rather uncommon.
Next to the Jumpmaster is the first version of the one-hand German Army knife, with the older, oval shaped thumb hole and a low-profile lock release.
The next one is the 2010 Dutch Army knife. This was the first Victorinox knife with 2 liner locks and 2 liner-locking blades, both featuring one-handed opening. This knife is pretty hard to find.
Next to the DAK is the most basic version of the Sentinel: it’s not one-handed, has a plain edge blade and has no corkscrew and no pocket clip.
The next one is an uncommon 90 ARMEE knife which was offered to Swiss Soldiers during the short period between the old Alox Soldier and the new 2008 Swiss Army knife (basically a one-hand Trekker).
The last knife is a red one-hand Trailmaster. This is basically a Trekker but with red scales and a different name (aimed at the European market I believe).
These knives (and more ;) ) will be for sale at EDC Source soon!
This is a red Victorinox Trailmaster. It is the same model as the pretty common One handed Trekker, but the Trekker usually has black scales instead of red ones. It’s also the same as the German Army Knife, but the GAK has no tweezers/toothpick.
This Trailmaster has the old, oval shaped thumb hole in the main blade. Current models have a round hole.
This is the 2010 model of the Dutch Army Knife (DAK).
It is closely related to the Victorinox DualPro knife, but has a Phillips screwdriver instead of a corkscrew. The DAK has olive green nylon scales with an embossed Dutch army emblem. There are no toothpick and tweezers.
Both large blades are one handed opening. The main blade is serrated, the other blade is an emergency blade or seat belt cutter. The DAK has 2 stainless steel locking liners: both blades and the flathead screwdriver/bottle opener are locking.
The one-handed German Army Knife (OH-GAK) replaced the 108mm GAK in 2003. This knife is almost identical as the one-handed Trekker, a 111mm liner locking knife with a one-handed, partially serrated main blade, a wood saw, a can opener and a locking can opener/screwdriver/pry bar. It also has a reamer/awl, Phillips screwdriver and a keyring.
The GAK has olive drab green scales with a German Army eagle molded in the front scale and lacks the toothpick and tweezers of the Trekker.
