This straight square shank 18K hallmark stamp is precision cut from heat-treated tool steel, designed for marking gold alloys containing no less than 75% pure gold by weight. The straight shank configuration is ideal for stamping flat surfaces, leaving a clean, sunken impression with each strike.
The 1/25" (1.00mm) measurement refers to the height of the impression, not the width. If you need to mark the inside of rings or curved interior surfaces, a bent stamp is recommended instead of this straight style.
