I'm ordering a custom stamp from harpers or everstamp and was wondering if I can stamp my knives right out of the forge or will this destroy the stamp. Also this stamp is a solid silhouette of a swallow in flight (special meaning to me) and was thinking of ordering a size around 3/16". Is this too small, most of my blades are around an inch wide and don't want something too over powering. Any suggestions would be much appreciated.
