How is the blue color achieved on the blade itself?

 Updated Mar 2026

The blue tone seen on select blades in this collection is produced through a controlled oxidation process applied to the polished carbon steel surface. By carefully regulating heat or applying specific chemical treatments, the craftsman develops a stable iron oxide layer that refracts light to produce blue and blue-grey hues. This is essentially the same principle behind blued firearms - a surface treatment that bonds to the metal rather than sitting on top of it like paint. The resulting color is durable under normal display conditions, though it can be affected by harsh cleaning agents or prolonged exposure to moisture. For this reason, blue-bladed pieces should always be wiped clean with a dry cloth and given a very light application of protective oil rather than any abrasive or solvent-based cleaner.
