Item description from the seller
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.
