Product Description
The Kershaw Launch 4 Blue (7500BLU) is the quintessential California-legal automatic knife, blending a striking electric blue aesthetic with high-performance American engineering. Precisely designed with a 1.9-inch blade, this compact powerhouse is built to comply with more restrictive automatic knife regulations while delivering the snappy, authoritative deployment the Launch series is famous for. Lightweight, stylish, and remarkably tough, the Launch 4 is the ultimate "fifth pocket" EDC tool.
The spear point blade is crafted from CPM-154 powder metallurgy steel, an elite alloy favored for its exceptional edge retention, toughness, and corrosion resistance. Featuring a clean satin finish and a flat grind for superior slicing, the blade is as functional as it is attractive. The handle is machined from 6061-T6 aluminum, anodized in a vibrant blue that provides a durable, fade-resistant finish. With a total weight of just 1.8 ounces, the Launch 4 offers a "strong opening kick" that defies its small footprint.
