The Otter Messer folding UK legal carry pocket knife is hand made in Solingen, Germany and uses unalloyed, C75 carbon steel, which gives an extremely sharp, long lasting cutting edge. Due to the hardness of the blade this makes an ideal work knife, requiring less frequent re-sharpening. Note: carbon steel knives need to be cleaned and oiled after use to prevent corrosion. Surface corrosion can be removed with fine emery cloth. All prices shown include standard UK delivery.
