Etched

The etching process starts with the knife being thoroughly cleaned to remove any oils or residues. A protective mask may be applied to the areas not intended to be etched. The blade is then submerged in an acidic solution, such as ferric chloride, which reacts with the different layers of steel at varying rates. This creates a layer of dark oxid...

An etched finish is created by masking parts of the blade and exposing the unmasked steel to a controlled acid bath (typically ferric chloride for knife steels). The acid removes material at a uniform rate, leaving a slightly recessed, matte pattern where exposed. On clad blades, etching also reveals the contrast between core and cladding steels.

Etched finishes are most commonly used to highlight damascus patterns by bringing out contrast between the layered steels. Less commonly, etching is used decoratively on monosteel blades to add brand marks, logos, or pattern designs.

Wash by hand with mild detergent. Avoid alkaline cleaners and prolonged acid contact (citrus, vinegar) which can deepen or alter the etched contrast over years of use. The pattern is etched INTO the steel, not painted on — it will not chip or peel, but heavy polishing or aggressive sharpening near the etched zone can fade the contrast.
