Material

Carbon steel
Carbon steel C75 is an unalloyed or low-alloy steel (also known as cast or carbon steel), which mainly contains carbon and hardly any other alloy elements. This gives it a very fine structure. The steel will rust and therefore requires special care. The blade becomes discoloured when cutting, for example, apples or onions, which is not a quality deficit, but a unique feature of the material. It is valued for its level of sharpness and cutting durability of the blades.
Stainless steel 3034
This steel is alloyed with more than 11% chrome and is therefore rust-proof. Viewed under a microscope the structure is coarser due to the high amount of chrome. This is the reason why this steel has a lower cutting durability compared to carbon steel. Benefits of the rust-proof blade are that it requires little care and is also taste-neutral (e.g. when cutting apples).
Brass
Brass is a copper-zinc alloy that has been used for approx. 5000 years. Its golden-yellow colour upgrades the appearance of tools and parts. Brass has a high corrosion resistance and good malleability and machinability. Like other copper alloys, it develops a patina over time.
Sapeli
This tree, which is common in Africa, has a gold or reddish-brown colour. The wood, which is also used to construct boats, has a unique structure, colouring and shine.
Grenadilla wood
This wood from Africa has a dense and water-repellent surface. The colour ranges from brown-violet to black. It is one of the heaviest woods, very finely structured and has a very smooth and slightly oily surface. Our knife handles made of grenadilla (Dalbergia Melanoxylon) are pre-registered stock of EG-prescriptionNr.338/97 of 02.01.2017. They are registered by the lower nature conservation authority.
Olive wood
These trees belong to the olive family. The wood is one of the hardest in the world. Its grain in particular makes it unique. Knife scales/handles made with olive wood have a good haptic.
Bone
The bone handles of our knives are made from cattle bones. The fat is removed from the bone, which is then boiled and bleached. This process is very time-consuming and requires a lot of skill. The grain of every piece is different. OTTER-Messer GmbH, Inh. Frank Rommel, Schwertstr. 35, 42651 Solingen is registered with the number DE 05 122 0001 14.7 as a processing manufacture, of minor animal products, bone, horn, hooves as well as products of the named material (BHHP)
Staghorn
German buckhorn is used for OTTER knives. The handles retain the original antler grain structure. Buckhorn is impervious to dirt and scratches. OTTER-Messer GmbH, Inh. Frank Rommel, Schwertstr. 35, 42651 Solingen is registered with the number DE 05 122 0001 14.7 as a processing manufacture, of minor animal products, bone, horn, hooves as well as products of the named material (BHHP)
