ImpressArt Ergo-Angle Metal Stamping Hammer

Its angled brass head and ergonomic handle help deliver controlled strikes when stamping jewelry blanks.

Not for: Anyone needing letter stamps or a complete starter kit.

Not for: Anyone only marking plain names and dates.

Blank hardness. Aluminum, copper, brass, sterling and pewter stamp easily. Stainless steel needs hardened stamps and much heavier blows. Soft stamps mushroom or chip on hard blanks.
Bench block. Stamp on a solid steel bench block placed on a sturdy, non-bouncy surface. Bounce gives shallow or doubled impressions.
Hammer. Use a dedicated brass or stamping hammer with enough weight for one strike. Multiple strikes ghost the letters.
Alignment. Use guide tape or a stamp alignment tool and check the orientation marks on each stamp. Crooked or upside-down letters are the most common ruined blanks.

Why are my letters uneven in depth?

Usually the stamp is tilted or the surface bounces. Hold it vertical, use a steel block on solid footing and strike once firmly.
