Spring-Actuated Window Breaker

A purpose-built emergency tool measuring ~9.5 × 17.8 cm, fabricated from lightweight aluminum alloy with textured sandblasted + oxidized surface for secure handling in all weather conditions. Core functionality delivered via a tungsten steel tip rated at Rockwell 65 hardness — proven effective against automotive tempered glass and seat belt webbing. Operates via a responsive gun-type spring mechanism that amplifies fingertip force into decisive impact — fully reusable, silent, and intuitive. U-shaped finger containment area prevents over-insertion and minimises surface abrasion risk. Its compact profile and key-like weight allow seamless integration into daily driver routines — clipped to keys, stowed in door pockets, or placed beside sat-nav units. Developed with input from UK roadside assistance providers: prioritises speed, simplicity, and single-motion operation. Compatible with right-hand-drive vehicle cabin layouts — optimised reach for driver-side window access and front passenger belt cutting. Includes practice glass for skill retention and clear English-language instructions aligned with DVSA-recommended emergency response protocols. What's in the box: 1 × safety hammer, 1 × safety-rated practice glass (100mm × 100mm), 1 × step-by-step UK English manual.
