The Gerber Mark II is a fighting knife manufactured by Gerber Legendary Blades from 1967 to 2000, with an additional limited run of 1500 in 2002, and full production resuming as of July 2008. It was designed by retired US Army Captain Bud Holzman, who based the pattern on a Roman Mainz Gladius.
It has a 6.5 inch (16.5 cm) double-edged spear-point wasp-waisted blade, and uses a distinctive handle similar to that of the Fairbairn-Sykes Fighting Knife developed during World War II for the British Commandos. The Mark II was commonly carried by U.S. troops in the Vietnam War, and was second only to the Ka-Bar knife in fame. The MK II was the suggested blade in Paladin Press's controversial how-to book, Hit Man: A Technical Manual for Independent Contractors.
During the Vietnam war, the first production run of this knife had a 5-degree offset between the blade and the grip in order to ride in the sheath more comfortably and give the user a grip similar to that of a fencing foil. This design feature lead to a significant amount of knives being returned by users for having a "bent blade", so Gerber discontinued that element on subsequent production runs. In the 1970s, the military's base/post exchanges discontinued selling these knives, reasoning that they were "not in good taste" or "too brutal".Al Mar, then working for Gerber as a knife designer, added the sawtooth serrations toward the hilt, marketing the knife as a "survival aid", making it more appealing to the PX System, which resumed selling the Mark II as a survival knife, rather than a fighting knife.
Mark II or Mark 2 often refers to the second version of a product, frequently military hardware. "Mark", meaning "model" or "variant", can be abbreviated "Mk."

British heavy tanks were a series of related vehicles developed by the British Army during the First World War. The Mark I was the world's first tank to enter combat. Born of the need to break the domination of trenches, barbed wire and machine guns over the battlefields of the Western Front, it was the first vehicle to be named "tank", a name chosen as an expedient to maintain secrecy and to disguise its true purpose. It was developed to be able to cross trenches, resist small-arms fire, travel over difficult terrain, carry supplies, and to capture fortified enemy positions. It is regarded as successful in many respects, but suffered from many problems owing to its primitive nature.
The Mark I entered service in August 1916, and was first used in action on the morning of 15 September 1916 during the Battle of Flers-Courcelette, part of the Somme Offensive. With the exception of the few interim Mark II and Mark III tanks, it was followed by the largely similar Mark IV, which first saw combat in June 1917. The Mark IV was used en masse (about 460 tanks) at the Battle of Cambrai in November 1917. The Mark V, with its much improved transmission, entered service in mid-1918.
Mark II is a rideable and user-operated robot built by the American company MegaBots Inc. The robot is scheduled to engage in a head-to-head fight with Kuratas, a robot built by Suidobashi Heavy Industry of Japan. Mark II made its debut in May 2015 at Maker Faire San Mateo. In August 2015, MegaBots announced plans to upgrade Mark II with melee capabilities in order to confront Kuratas, using funds from a Kickstarter campaign.
