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.
Micarta is a fibre-plastic composite in which an absorbent carrier material such as linen or wood is impregnated with phenolic resin. Once the resin has cured, the Micarta piece can be ground to shape. Differently coloured materials are often used to achieve a special grain.

It is excellent for hunting knives as it has enormous resistance and water resistance under changing conditions.
Smoked Oak
Smoked oak is oak wood that has been changed in colour. It is either fumigated with ammonia or ammonia spirit during "smoking", so the oak turns dark brown or even black. This process produces organically complex salts that are stable to ageing and light. These are not only responsible for the discoloration of the wood, but also for its suppleness and resistance to insect and fungal attack. It also makes it less brittle. The oak species, sessile oak and sessile oak, which is native to Central Europe, is best suited for this because it has a high tannin content.
Curly Birch
The Maserbirch can be found between the border region Russia and Eastern Finland. They reach an average diameter of 10 - 20 cm and are particularly famous for their unique grain of the so-called brown "veins" or "flames", which contrast with the rest of the very light wood.
The junipers are a plant genus of the heartwood trees and are evergreen trees or shrubs, which often do not even reach a height of 4m. However, they can live to be 600 years old. Since juniper is particularly slow-growing, the wood is correspondingly finer.

Typical for this tree species are also the narrow annual rings, which show a multiple characteristic wavy course. Also of interest is the clearly distinct colour play of the early and late wood.
The term damask, derived from Damascus, refers to a material composed of several types of steel and world-famous for its organic pattern, which only emerges after etching.

Two different types of steel are usually placed on top of each other in the form of plates and then heated. The two are then joined and the composite can be folded several times, superimposed again and pressed together. In order to obtain the typical damask pattern later, the steel must be heated after hardening. Whether the layers become lighter or darker depends on how high the steel alloy and carbon content are. Finally, the blade can be post-hardened and sealed.
The pistachio trees grow mainly in Iran, Turkey and the USA and can reach an age of 300 years. Despite its high hardness and weight, it is easy to process. The conspicuous yellow-green and black-brown colouring is particularly attractive. Due to the black colour even cracks are very attractive. These can also be filled with thin superglue and grinding dust.
Around 400 oak species belong to the plant genus oak. They can live to an incredible 1000 years and grow to an average height of 30 - 40m. Fossil finds prove that oaks existed more than 10 million years ago.

In addition to using the wood, acorns have also been used as feed for pigs and red deer since then. The oak is particularly tough, heavy, very durable and above all very hard. In addition, it can be used in many different ways, for example for furniture wood, stairs, parquet, veneer or for the handles of knives.
The plum tree, also called plum, can reach a height between 6 - 10m and is mainly cultivated because of its fruits. The heartwood shows red and violet tones (see picture), while the sapwood is rather light. It is known for its hardness, density and fine porosity, as well as for its even structure. In addition to its frequent use for smaller workpieces, such as knives, plum wood is also often used as firewood.
Nut Tree
The nut tree can reach a height between 15 - 25m as a medium-size tree, while the average diameter of the trunk is 60 - 80m. There are some differences and peculiarities in the colour and structure of the wood. A distinction is made between two species, the European walnut and the American walnut.
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).
Gold-coloured brass is one of the best-known copper alloys. The alloy is made of copper and zinc, whereby the colour is determined by the zinc content. A zinc content of less than 20 % produces a brownish to reddish colour, while a zinc content of more than 30 % produces a golden to white-yellow colour.

Brass was very popular as a material in the 3rd century BC. It established itself as a commodity metal as early as around 1,000 BC, when brass production was refined in Asia Minor. In particular, the minting of brass coins in the Roman Empire contributed greatly to the spread of the material. Later, vessels and objects of art were added.

Today brass enjoys a new popularity. The golden yellow colour gives our brass handles a noble appearance and makes them small pieces of jewellery in everyday life.
Sapeli or Sapeli mahogany belongs to the mahogany family. The tree known as Entandrophragma cyclindricum is native to West and Central Africa. There it grows up to 60 m high with a diameter of up to 2 meters. The wood has a strong golden to reddish brown colour and shows a very even grain. It is medium-hard to hard, but good to work with. Handle shells made of Sapeli are characterised by their robustness and durability.
Grenadilla is the wood of the tree known as Dalbergia melanoxylon, which belongs to the papilionaceous family. This tree is native to the dry savannah areas of the Sahel, from the East African savannahs to northern South Africa. There it grows to a height of about 5 to 8 metres and reaches a trunk diameter of up to 50 cm.

Grenadilla is often erroneously referred to as African ebony, Senegal ebony or Mozambique ebony, although it does not belong to the ebony family.

The heartwood is brown-black to black-purple in colour and is one of the densest and hardest woods in the world. It has relatively fine pores and therefore feels smooth and pleasant in the hand.
Olive wood
Olive wood has long been known as a material. Olive trees were already cultivated as useful plants in ancient times. The tree itself is used very versatilely. The wood is used in the manufacture of instruments, furniture and utensils - for example OTTER knives. The fruits are used both for oil production and directly as food. The resulting plant residues are further processed into fuel or bio-fuel. The olive or olive tree is also used symbolically, here as a sign of peace. And last but not least, it plays an important role in the history of the city of Athens. There the goddess Athena won the competition against the god Poseidon with the gift of an olive tree, which resulted in the city being named after her. Olive trees need a lot of time to grow. Therefore its wood is particularly hard and dense. This high density and the resulting fine pores also prevent the wood from absorbing foreign odours.

We only use heartwood for the handles of our knives. This is characterised not only by its robustness, but also by its attractive grain. Despite its high resistance, olive wood can turn dark in places during use. It is, like other woods, a living material. By the way: The most beautiful olive trees should grow in the coastal regions between Barcelona and Alicante.
Bone has been used as a material for tools and weapons since the Stone Age. Tools made of bone and stone are among the oldest proven tools of mankind. So it is no wonder that animal bone handles exert a very special fascination on us.

The material for our grip shells is extracted from Argentine cattle bones. In order to prepare it for processing, the bone marrow is first removed. The bone is then sterilized and degreased by boiling for a short time. Only then can the cattle bone be processed further.

Bone is a very durable material, especially if you take care of some things. Long, dry heat and too dry storage should be avoided, as should long uses in boiling water. Also solvent-containing cleaners and abrasives and not least also the dishwasher should be avoided. All these things can attack and impair the structure of the bone. In addition, no oil should come to the bone, otherwise it will discolour.
Deer horn is a traditional grip material, which is used particularly gladly with hunting knives. The term itself is actually misleading, because the antlers of deer are made of bone substance and not of horn with a bony core, as in sheep or goats.

In the processing stag horn is very similar to the bone. It must be prepared in advance by cooking and degreasing.

By the way: One theory says that the size and shape of the antlers depend on the region and the regular height of the snowfall. It seems that in northern, snow-intensive regions, such as moose and caribou, deer tend to form large, shovel-like antlers. With these antlers the deer can better push the snow aside in winter to get to the green fodder hidden underneath.
