Knife handles made of steamed, finely polished wood are rare. Knife handles made of steamed, finely polished apple tree wood are even rarer because apple tree wood, since it dries slowly, is not one of the typical commercial woods. However, it is very easy to work with due to its hardness, weight and durability. Herder in Solingen manufactures these knife handles with rarity value exclusively for Manufactum: even oiled for better surface protection.
