Description:
Juma Gem is a modern composite material developed for projects where both appearance and performance are in focus. The material consists of a carefully composed mixture of mineral-based components and resin, which provides a homogeneous, stable, and highly durable structure.
What truly sets Juma Gem apart is its visual expression. The material has a vivid, almost gemstone-like quality with strong colors and depth, giving the knife handle a unique and exclusive appearance. The various color options provide great design freedom and make it possible to create everything from subtle details to more eye-catching expressions.
Juma is also known for its excellent working properties. It can be sawed, milled, drilled, and sanded with high precision, yielding a smooth and fine surface. After polishing, the material attains a smooth, high-gloss finish, which impressively highlights both color and structure.
The material is highly resistant to moisture, oil, chemicals, and temperature changes, making it very stable in use. It does not crack easily and maintains its shape well over time, even under demanding conditions.
Its fine and dense structure also makes it well-suited for detailed work and precise adjustments. Whether used as a full handle or in combination with other materials, Juma Gem provides a professional and polished result.
For those who want a modern material with both visual impact and technical performance, Juma Gem is an excellent choice.
The result is a durable, maintenance-free, and visually striking knife handle – with a unique touch that truly stands out.
