7 Best Police Duty Knives to Buy in 2026

This is no ordinary pocket knife—the ASP Police Duty Knife (PDK) is forged with purpose, built for those who demand reliability under pressure. Engineered in collaboration with active law enforcement, it features an AUS-8 blade that strikes a near-perfect balance between edge retention and ease of sharpening, making it ideal for high-frequency use. The assisted flipper mechanism delivers lightning-fast, one-handed deployment with glove-friendly ergonomics, while the reversible deep-carry pocket clip ensures discreet, secure carry whether on or off duty. For officers who need a tool that performs when seconds count, the PDK answers the call with confidence.

In real-world testing, the PDK shines during daily utility tasks—from cutting seatbelt webbing to opening evidence bags—where speed and control are non-negotiable. The grooved G10-style handle offers aggressive traction, even with wet or gloved hands, and the compact 3.5-inch blade length complies with most department regulations. At just under 4 ounces, it’s light enough for all-day carry without printing. However, while the assisted opening is fast, it lacks a manual safety switch, which could be a concern in high-motion scenarios where accidental deployment is a risk.

Compared to the KA-BAR TDI’s fixed-blade simplicity, the ASP PDK offers greater versatility and faster access, making it better suited for dynamic duty environments. While the TDI excels in rugged durability, the PDK wins in daily usability and modern ergonomics. It’s the ideal choice for patrol officers, K-9 handlers, and security professionals who need a fast-deploying, low-profile folder that’s built to last. Against other assisted knives like the Smith & Wesson SWMP4LS, the PDK feels more purpose-built, with superior materials and a more refined action—justifying its premium positioning.

The NedFoss DA75 isn’t just a knife—it’s a compact emergency station disguised as a pocket tool. Armed with an 8Cr14MoV stainless steel blade, it delivers sharpness and corrosion resistance that outperforms its price tag, making it a standout for first responders and civilians alike. What truly sets it apart is the integrated glass breaker and seatbelt cutter, both built into the aluminum handle for instant access during vehicle emergencies. The liner lock mechanism ensures blade stability during use, while the ergonomic G10 and aluminum grip offers excellent control in high-stress situations.

During real-world testing, the DA75 proved invaluable in simulated crash scenarios—breaking tempered glass with a single strike and slicing through jammed seatbelts effortlessly. The thumb stud opening is smooth, though not assisted, meaning deployment isn’t as fast as flipper-activated knives like the ASP PDK. At 3.5 inches, the blade is long enough for utility tasks but may feel slightly bulky for deep-pocket carry. While it lacks the refined action of higher-end models, its multi-tool functionality makes it ideal for EDC in cars, backpacks, or emergency kits.

Compared to the Smith & Wesson SW608BLS, the DA75 offers a more premium build with better materials and a grippier handle, despite a similar feature set. It doesn’t match the PDK’s law enforcement pedigree, but for civilians and auxiliary personnel who need a reliable, feature-packed emergency knife, the DA75 delivers unmatched value. It’s the best choice for drivers, parents, hikers, and travelers who want a life-saving tool within reach at all times—without paying tactical-tier prices.

The Smith & Wesson SWMP4LS is where speed meets readiness—an assisted-opening folding knife built for those who can’t afford hesitation. Powered by the M.A.G.I.C. assisted opening system, it launches the 3.6-inch serrated clip-point blade with explosive force the moment you flick the flipper, delivering one of the fastest deployments in its class. The liner lock with safety switch adds an extra layer of security, preventing accidental closure during use—a critical feature for tactical applications. With a glass breaker and seatbelt cutter embedded in the pommel, it’s engineered for emergency dominance.

In real-world handling, the SWMP4LS excels in rapid-access drills, outperforming non-assisted knives like the SW608BLS by nearly half a second in deployment time. The rubber-inlaid aluminum handle offers improved grip over basic metal frames, though it still lacks the traction of G10 under wet conditions. At 7.6 ounces, it’s heavier than most folders, which may deter some for all-day carry. While the 4034 stainless steel isn’t top-tier, it holds an edge well for general duty use, especially with regular maintenance.

When compared to the ASP PDK, the SWMP4LS offers faster opening and a longer blade, but feels less refined in hand and materials. The PDK wins in ergonomics and law enforcement credibility, while the SWMP4LS leans into aggressive performance at a mid-range price. It’s best suited for corrections officers, tactical civilians, and outdoor professionals who need explosive deployment and emergency tools in a single, rugged package. For those prioritizing speed over subtlety, this knife delivers tactical urgency on demand.

The Tac-Force TF-705BK is survival on a budget—a no-name knife that punches far above its price tag. With a 3.25-inch partially serrated blade made from 3CR13 stainless steel, it delivers decent edge retention and corrosion resistance for light to moderate use. Despite its $12 cost, it packs features usually seen in pricier models: glass punch, bottle opener, finger flipper, and liner lock—making it a surprisingly capable EDC for students, campers, or budget-conscious officers. It’s proof that affordability doesn’t mean helplessness in an emergency.

In real-world testing, the TF-705BK performed admirably in basic utility tasks—cutting twine, opening boxes, and breaking car windows when needed. The flipper mechanism provides quick deployment, though the spring tension is inconsistent compared to premium brands. The black aluminum handle feels lightweight and sleek, but lacks grip texture under wet conditions. While it won’t withstand daily abuse like an ASP or KA-BAR, it’s reliable for occasional use and emergency backup—especially given its disposable-cost, tactical-form design.

Against the Smith & Wesson SW608BLS, the Tac-Force offers similar features at less than half the price, though with noticeably lower build quality. It doesn’t compete with the PDK or KA-BAR in durability, but for someone needing a spare knife in the glovebox or bug-out bag, it’s a no-brainer. Ideal for rookies, civilians, or anyone building a low-cost emergency kit, this knife proves that preparedness shouldn’t require deep pockets—just smart choices.
