Your Discreet Lifesaver​​ This isn’t jewelry—it’s a NATO-spec survival tool disguised as a sleek ring. The tungsten carbide tip shatters tempered glass with 9kg of pressure (tested on 6mm side windows). ​​Engineered for Swift Action​​ ✔ ​​Covert Glass Breaker​​ – Hidden spike protrudes 2.3mm only upon impact (avoids accidental snags). ✔ ​​Pressure Amplifier​​ – 120° angled edges focus force like a tactical pen (see FBI pressure point charts). ✔ ​​Hypoallergenic Metal​​ – 316L surgical steel resists saltwater corrosion (ideal for swimmers/divers). ✔ ​​Universal Sizing​​ – Micro-adjustable inner groove fits knuckle sizes 7-14 (US ring standards). ✔ ​​Stealth Advantage​​ – Matte finish prevents light reflection during nighttime use. ​​When Seconds Determine Survival​​ ​​Subway Emergencies​​: Break window within 3 seconds of smoke inhalation (OSHA training protocol). ​​Parking Garage Threats​​: Strike with ring’s ridge to disorient attackers (non-lethal compliance). ​​Wilderness SOS​​: Use metallic sheen for daylight signaling at 1km visibility. ​​Carry Confidence, Not Fear​​ Note: Spike retracts automatically after use. Includes paracord necklace adapter for alternate wear.
