This straight marking stamp reads "10K"; ideal for quality-marking designs made with 10-karat gold. The stamp is precision-etched from 5/16' water-hardened tool steel and heat-treated to 58/60 HRC, delivering crisp, detailed surfaces and a long service life. Stamps with a straight shank have a flat tip face that's perpendicular to the tool shank. These stamps are perfect for marking flat surfaces such as quality or brand tags, discs, stampings and other components.
For best results—and because any stamped mark is not easy to remove once it's made—it's important to practice before attempting to mark your jewelry designs. Scrap pieces of sheet or base metal ring blanks are ideal for helping you get the feel of both the stamp and the power needed for an effective hammer strike. Use a brass mallet to strike the stamp to help prevent damage to your stamp, and support your workpiece on a bench block or an anvil. Finally, do your stamping before setting stones so that there is no risk of damaging settings or loosening set stones.
