This is the Ka-Bar Corser Folder, it’s a folding pocket knife and part of the company’s USSF (United States Space Force) product line.

On April Fools Day of 2019 American knifemaker Ka-Bar made a lighthearted post on their social media channels about a new model called the “Space-Bar,” a fighting knife designed for the use in space by the then-new United States Space Force.

As it happens people loved the idea, in fact they loved it so much so that Ka-Bar went and trademarked “USSF” for use in knife and tool making, so they could actually make the Space-Bar a reality. The knife was officially released for sale – while it has its roots in comedy the knife itself is just as capable as any of Ka-Bar’s other battle-tested knives.

Since 2019 Ka-Bar has released a number of other USSF products including the Bridge Breacher, the TDI Astro MP, and the Corser Folder.

The Unusual Origins Of The Name “Ka-Bar”

During WWII the United States Marine Corps recognized the need for a new combat knife to replace the earlier models. The Marine Corps reached out to several knife manufacturers, including Union Cutlery Company, Ka-Bar’s original company name, to design and produce a reliable and versatile combat knife.

The Union Cutlery Company eagerly took up the challenge and started working on the project. The company’s designers, led by a man named Howard E. Cole, developed a new knife design that incorporated feedback and requirements from the Marine Corps.

The knife featured a 7 inch blade made of high-carbon steel, with a clip point, and a serrated section near the handle. It had full tang construction, meaning the blade extended all the way through the handle for added strength. The knife’s design allowed for effective thrusting, slashing, and cutting actions, making it ideal for combat situations.

After extensive testing and refinement, the knife design was approved by the Marine Corps and officially adopted as the standard issue fighting/utility knife for the Marines. The knife quickly gained popularity among the troops, earning a reputation for its durability and effectiveness in the field.

To distinguish this new fighting knife from other models, the Union Cutlery Company wanted to give it a unique name. They ran a contest among their employees, inviting suggestions for a name that would capture the knife’s qualities and the spirit of the Marine Corps.

One of the company’s employees, a lady named Mary Elizabeth Hain, submitted the name “Ka-Bar.” The name was inspired by a testimonial letter the company received from a hunter, who recounted how he had used the knife to kill a bear that had attacked him. The letter was damaged badly when it arrived, but according to what could be read of the hunter’s words he had used the knife to kill a bear, though only the letters “k a b ar” were legible.

The name “Ka-Bar” resonated with the Union Cutlery Company, and they decided to adopt it as the official name for their new combat knife. It became so popular that they later adopted it as the name for the company as a whole.
