Carbon fiber — made in the USA.
A precision-crafted metal-free personal safety ring built for everyday carry and outdoor use. Made entirely from PET-CF (polyethylene terephthalate with carbon-fiber infusion) — a high-grade, 100% non-metallic composite. Not a gram of metal. Not a sharpened edge. Just a capable, responsible tool.
Designed to sit comfortably on one finger, the Black Talon puts a blunt non-sharpened spike within instant reach. It delivers precision control and retention without functioning as a cutting weapon or multi-finger impact device — a deliberate design choice that keeps it outside the legal categories that prohibit traditional knuckle weapons in most U.S. jurisdictions.
PET-CF — Polyethylene Terephthalate, Carbon-Fiber-Infused
PET-CF is a high-performance thermoplastic composite reinforced with chopped carbon fiber throughout its structure. It delivers far superior rigidity and impact resistance compared to standard plastics — while remaining dramatically lighter than any metal.
Key properties:
PET-CF maintains its rigidity under flex and pressure stress — making it ideal for tools that must hold their shape under real-world use. The same non-metallic construction means the Black Talon can accompany you in contexts where metal is impractical, unwanted, or scrutinized.
All sizes share the same spike profile, ring geometry, and design. The difference between sizes is inner ring diameter (grip size), overall dimensions, and weight.

| Medium – No Grip | 0.67″ / 17 mm | 6.3″ × 2.1″ × 0.4″ | 18 g / 0.63 oz |
| Medium | 0.67″ / 17 mm | 6.3″ × 2.1″ × 0.4″ | 20 g / 0.71 oz |
| Large | 0.75″ / 19 mm | 6.8″ × 2.2″ × 0.4″ | 24 g / 0.85 oz |
