Kershaw Collateral Spring Assist Knife

The Kershaw Collateral Spring Assist Knife (Model 5500) is a compact, purpose-built EDC blade designed for tactical professionals, outdoor enthusiasts, and automotive technicians who need reliable cutting performance in tight spaces. This spring-assist knife features a 3.25-inch clip point blade in satin finish with sanded flats, paired with stainless steel handles finished in titanium carbo-nitride coating and carbon fiber inserts for a lightweight yet durable construction.

The blade material is 8Cr13MoV stainless steel, a mid-range alloy known for holding a serviceable edge while remaining easy to maintain in field conditions. At 7.75 inches overall length with a 4.5-inch handle, the Collateral balances deployable blade length with pocket-friendly proportions. The reversible pocket clip supports tip-up carry only but accommodates both left- and right-hand users, making it accessible regardless of dominant hand. At just 0.31 lbs, the knife introduces minimal weight penalty to daily carry while maintaining sufficient mass for positive cutting control.

This model suits professionals working in automotive service, equipment maintenance, search and rescue, and tactical operations where a fast-deploying blade must perform reliably without fouling or binding. The spring-assist mechanism enables single-handed opening from pocket carry, critical when the other hand is occupied with a tool, vehicle component, or safety line. The sanded blade flats reduce light reflection—a practical consideration for fieldwork where discretion matters. The combination of stainless construction and corrosion-resistant coatings makes the Kershaw Collateral suitable for humid or coastal environments without excessive maintenance.
