Finishing
Subsequently to grinding the blade is polished to various degrees of gloss. The best finish is poli glace or mirror finish. Mirror finish is the only finish used if gold leafing is to be part of the decoration of the blade.[1]
Satin finish requires less polishing time and therefore is not as expensive to produce. This finish is mostly used with black acid etching. Satin finish can sometimes be applied, as a compromise, to the back of the blade while the mirror finish and gold leafing are applied to the more visible front of the blade. This way the blade will not be as expensive as a fully mirror finished one.[1]
