Blades that have been partially transformed to martensite (by edge quench, or however) respond unevenly to the etching process - usually the hardened steel is more acid resistant, and the pattern etchs less deeply - but it depends on the type of acid, degree of polish, many variables.
Is there any difference in the depth of the pattern on this sword, or is it only a color change?
