Smith & Wesson M&P Border Guard Knife 4" Blade Black

The Smith & Wesson M&P Border Guard Knife with 4-inch blade is a spring-assisted tactical folder engineered for law enforcement, security professionals, and first responders who require rapid blade deployment in high-pressure situations. Built on the Border Guard platform, this knife combines the trusted Smith & Wesson M&P brand reputation with a compact, carry-friendly design optimized for duty belt integration and quick access.

The 4-inch blade provides sufficient edge length for utility cuts, evidence handling, and emergency tasks while maintaining a folded profile that fits standard issue holsters and duty gear. Black finish reduces glint and corrosion, critical for personnel operating in wet or outdoor environments. Weighing just 0.54 pounds, the Border Guard minimizes fatigue during extended patrol shifts. Spring-assist activation ensures reliable blade extension under adverse conditions—gloved hands, low-light deployment, high-stress scenarios—where manual opening times matter operationally.

This platform serves border patrol agents, correctional officers, security contractors, and tactical operators who need a backup blade that deploys instantly and cuts cleanly. The compact 5.5-inch overall length in the palm makes it suitable for plainclothes carry without printing or snagging. Law enforcement procurement specifications often favor spring-assist mechanisms for reliability and consistent performance across departments and certifications.
