Kirinite is a thermoset cast acrylic resin celebrated for its deep, vibrant colour pigmentation and exceptional durability. Its versatility and striking appearance have made it a favourite across multiple industries.

​

Kirinite is a brand of GPS Agencies Ltd (UK) and Eagle Grips Inc (USA). GPS had worked with this unique decorative acrylic for many years and recognised its potential within the knife‑making market. At the same time, Eagle Grips was exploring innovative materials to reinvent the custom gun‑grip industry.

​

The two companies share a long‑standing relationship—one that spans generations—built on trust, craftsmanship, and shared values. During a meeting at GPS, both teams quickly realised the remarkable potential of this material. With thoughtful planning and branding—including a name inspired by the eldest daughter of Eagle Grips’ CEO—Kirinite was created.

​

Since its launch, Kirinite has grown far beyond expectations, yet its foundations remain unchanged: a family‑built brand developed by two family‑run businesses.
