Gemstone

Origin : USA.

Comments : it is a mixture of stone powder (85%) and resin. Sold in handles and blocks.

It is a material that is much easier to work than stone - it can be cut with a hacksaw.

Reconstituted stone is a material of choice for cutlery manufacturers looking to create unique and durable knife handles. Engineered stones are made by mixing natural stone particles with a synthetic resin to create a strong, durable material.

The most common engineered stones used in cutlery are onyx, jasper, turquoise and malachite. Onyx is a black stone with white veins, while jasper can have a variety of colors and patterns, ranging from red to green to brown. Turquoise is a blue-green stone and malachite is a dark green stone with lighter colored bands.

Reconstituted stone knife handles are popular because of their unique appearance and durability. Their texture and colors vary from piece to piece, giving the knives a personalized, handcrafted look. 

When working with reconstituted stones, it is important to take proper safety precautions. As with any cutlery material, it is recommended to wear protective gloves and safety glasses to avoid injury.
