The KA-BAR brand originated as a trademark of the Tidioute Cutlery Company. Tidioute was later taken over & renamed the Union Cutlery Company which continued making the brand until Union eventually adopted it as the company name in 1952. Cutco Corporation later acquired the company in 1996.
Here’s my other purchase, it’s gorgeous. The shield side of the blade has the Union Cutlery stamp but the backside only has P A T. Enjoy and thanks for the comments on my blades.
