Description:
Juma Gem liner is a modern composite material specifically developed for details and spacers in knife making. With its thin profile and fine structure, it is perfect for creating contrasts and visual transitions between different materials in the handle.
The material consists of a carefully composed blend of minerals and resin, which provides a homogeneous and highly stable structure. This makes the liner both durable and resistant to moisture, chemicals, and temperature changes, while maintaining its shape over time.
What truly sets Juma Gem apart from other spacer materials is its fine and detailed pattern. Even in thin sheets, the structure is clearly visible, adding life and depth to the knife handle – without becoming overpowering.
The liners are typically supplied in dimensions around 3x50x305 mm, making them easy to adapt to various projects. They can be sawed, sanded, and shaped with high precision, providing a clean and predictable result throughout the entire work process.
Juma is also known for its excellent technical properties. The material has high surface hardness, low water absorption, and minimal risk of cracking, while it can also be polished to a smooth and exclusive finish.
With a wide selection of colors, Juma Gem liner gives you the opportunity to add subtle details or bold contrasts to the design. Whether used as a thin accent line or as a distinct visual transition, it helps elevate the overall impression of the knife.
The result is a precise, durable, and visually exciting knife handle – where even the smallest details play an important role.
