Battle Bud Blue & Black USMC – spring-assisted tanto pocket knife

This pocket knife features an 8.9cm tanto blade made from 3Cr13 stainless steel with a spring-assisted opening mechanism. The knife weighs 181g and includes a frame lock for secure blade retention during use.

Construction and materials

The blade measures 8.89cm with a plain-edge grind and tanto point geometry. Total length when open is 21.59cm, folding down to 12.7cm for pocket carry. The black handle features blue accents and includes a pocket clip for secure attachment.

Application and use

Designed for everyday carry and general cutting tasks, this pocket knife suits users requiring a reliable folding blade for rope, plastic, and cardboard cutting. The tanto tip provides enhanced piercing capability for tougher materials.

Integration and compatibility

The spring-assisted mechanism enables one-handed opening, while the frame lock ensures the blade stays locked during use. The integrated pocket clip allows for tip-up carry in standard pockets or gear pouches.

Maintenance and lifecycle

The 3Cr13 steel requires regular sharpening with intensive use but offers easy maintenance for beginners. Clean the blade with a damp cloth and oil the pivot monthly to maintain smooth operation. The black coating provides basic corrosion resistance but may wear with heavy use.
