Canada’s Joint Task Force 2 (aka JTF2) is a special forces unit that serves as the centerpiece of the country’s special military operations. It’s widely considered one of the most elite forces of its kind in the world. They were part of the teams hunting Serbian snipers who were targeting United Nations forces. In 2004, the United States government recognized them with the Presidential Unit Citation. They have performed other duties ranging from guarding major political figures overseas to carrying out classified counter-terrorism missions. Little is known about the unit. However, reliable sources claim that each member is assigned a Karambit — a special knife designed for self-defense and combat. It features a grip that rests comfortably in the hand making it difficult to disarm anyone holding one.

#9: Ballistic Knife (Russia’s Spetsnaz GRU)

In most countries, ballistic knives are banned for non-military use — even if they’re technically some of the best tactical knives — because they propel their blades through the air like bullets. If your country allows civilians to purchase ballistic knives for non-military use, then this knife is another option to consider. They feature prominently in the arsenal of the Spetsnaz GRU, the Russian Special Forces unit which focuses on (counter)intelligence missions.

#10: Ka-Bar (U.S. Marine Corps)

Ka-Bar is a classic weapon commonly used by the American Marine Corps and one of the high-performance knives that many Special Forces around the world admire. The Marine Corps settled on this knife when they realized that most of the knives they used during the Second World War were ineffective. Most were good for combat use but didn’t solve many of their day-to-day survival needs. The Ka-Bar was designed perfectly with lethal elements just like previous knives but added other elements for wire cutters, crate openers, and much more.
