The greatest "enemy" of any piece of cutlery is WATER, therefore, the right cleaning of a folding knife blade should always be done only with a wet cloth, never submerging it in water, dishwasher, etc..., drying insistently afterwards to avoid possible oxidation effects on the steel, even on stainless steel, try not to touch the handle. If it is also necessary to clean the handle, we will proceed in the same way, but with attention that it is completely dry to avoid deterioration, especially if it is made of a natural material such as wood, bone, horn, etc... Finally, we recommend lubricate the axis, as well as the inside of the handle of any folding knife, with mineral oil, never vegetable, to avoid oxidation that causes the "hardening" of the action of opening and closing our tool.
