This bent square shank 12K hallmark stamp is precision cut from heat-treated tool steel and designed for marking precious metals. The bent shank design — also known as a gooseneck stamp — allows access to curved or recessed surfaces, making it well suited for hallmarking the inside of rings and other hard-to-reach areas. The stamp produces a clean, sunken impression of the 12K mark directly into precious metal.
