The Ergo-Angle Metal Stamping Hammer is a signature ImpressArt tool and an important asset contributing to elevated jewelry stamping. Its weighted brass head and ergonomic features help achieve evenly stamped impressions. The development of the Ergo-Angle Hammer involved a series of field tests performed by ImpressArt Certified Bench Jewelers, who have identified the optimal striking angle and holding points for precision and comfort when working with metal stamps. Experience the Ergo-Angle on your next metal stamped project! NOTE: being that the brass head is softer than steel stamps, the brass head will dent and flake when stamping. This is by design and will not affect the quality of your stamping.
