Planishing Hammers are generally used for smoothing metal.  The round side is used if the metal has previous raising hammer marks and these need to be smoothed out. The flat side will refine the hammer marks from the rounded side of the planishing hammer to a nearly smooth finish.  This hammer has faces which measure 19mm in diameter (approximately 3/4") and has a head length of 74mm (just under 3") making it a good, general use hammer.  Can also be used for sizing rings, shaping bezels and forming metal against mandrels and stakes.  Overall length 220mm (approx. 8-1/2"). Made in Vietnam.
