12 Ways to Create Texture on Metal & How to Hammer …

I love hammering on metal—and I bet I''m not the only one! The tension release, the change in the metal, even the sound—it''s all very satisfying. Most of the hammering I do in the studio is for texturing metal, which has me on a never-ending search for new hammers that will allow me to create texture on metal in new ways. That can get expensive! I was inspired when I found new texturing
