Juma Black is a high-quality plastic with a very high mineral content. The material is very hard and shatter-proof, as well as very easy to care for, as it is completely resistant to water, grease, and cleaning agents. Juma is also particularly characterized by its good thermal properties, making it comfortable to hold at all times. Juma Black is deep black, and the polished surface exhibits a fine sheen.

Karelian curly birch is a small birch species native to Northern Europe, primarily in the border region between Finland and Russia. Due to its slow growth, the light gray to light brown wood exhibits a strong, contrasting grain. Karelian curly birch is a typical knife handle for traditional Scandinavian knives and is unmistakable due to its striking grain.

Bog oak is not a separate wood species: It is actually a subfossil oak trunk, up to 5,000 years old, that has lain in northern German bogs and waterways. When such a trunk is found and recovered from a bog, it must first undergo a complex drying process that takes several years before it can be processed. The color varies between brownish and bluish-black tones.

Olive wood is undoubtedly one of the most beautiful woods. Nesmuk uses exclusively hand-picked pieces of wild olive wood from a specific region in Spain—with a particularly spectacular grain, ranging from light brown to golden yellow, wildly patterned with dark streaks. The handles are deliberately left unpolished to preserve the pleasantly soft feel of the olive wood.

Walnut burl, in the quality selected by Nesmuk, is one of the rarest and most expensive European woods. The true walnut is found primarily in Central and Southern Europe. The heartwood alone is a sought-after precious wood, and the valuable wood of the rare burls is even more beautiful: Very heavy and hard, walnut burl is characterized by its fine, dark to golden brown grain.

Desert ironwood originates from the Sonoran Desert in the USA and Mexico, where it is one of the longest-living tree species and can live up to 1,500 years. The tree is strictly protected, and only small amounts of naturally dead wood are available. It is one of the densest, heaviest, and hardest woods in the world and requires complex and demanding processing.

Juniper wood is often used for knife handles due to its hardness, beauty, and durability. It has a fine, even grain and a warm, reddish-brown color that develops an attractive patina over time. In addition to its aesthetic qualities, juniper wood is characterized by its robustness and durability. It also lends the knife handle a pleasant feel and ensures a good grip.
