Nearly undetectable until it’s deployed and cutting, the B-2 Nano Blade is the world’s smallest tactical pocket knife. Made of corrosion-resistant 440C Stainless steel, it weighs less than one ounce with diminutive dimensions: 48mm in length, 20mm in width and only 5mm thick. It features a blade split with serrated teeth and a smooth, sharp tip as well as a mini carabiner clip for EDC use. A funded Kickstarter.
