Ek Commando Knife Co. is a legendary American knife manufacturer founded by John Ek in 1941 in Hamden, Connecticut. Originally crafted for U.S. servicemen during World War II, Ek knives gained acclaim for their robust full-tang construction and ergonomic design, making them a preferred choice in close-quarters combat. These knives have been carried by American forces in major conflicts including WWII, Korea, Vietnam, Iraq, and Afghanistan. Notable figures such as President Franklin D. Roosevelt and General George S. Patton were known to own Ek knives. In 2014, the brand was acquired by KA-BAR, which continues to produce Ek knives that honor the original craftsmanship while incorporating modern materials and techniques.
