Planishing
Planishing (from the
Latin planus, "flat") is a
metalworking technique used to smooth
sheet metal.After a piece of metal has been roughly formed by techniques such as
sinking or
raising, the surface will have irregular indentations and bumps. To remove these imperfections, the piece is hammered between a flat or slightly curved
hammer and a special forming object known as a planishing stake. Using repeated, relatively soft blows, the piece is smoothed toward the curvature of the stake.

About
Planishing
The final
hammer work done on a piece. Anywhere from 1000-10000 hammer strokes are required to provide a smooth, even layer of faceted hammer marks ready for sanding and
polishing . Additionally, if the piece is not to be heat-treated, then a complete planishing lends a good hammer-hardening to the piece, helping it to resist deforming under the stress of combat. See also
