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.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eBent square shank (gooseneck) design for marking interior surfaces such as ring shanks\u003c\/li\u003e\n\u003cli\u003ePrecision cut heat-treated tool steel construction\u003c\/li\u003e\n\u003cli\u003eProduces sunken hallmark impressions on precious metals\u003c\/li\u003e\n\u003cli\u003eMarked with the 12K designation\u003c\/li\u003e\n\u003cli\u003eMade in the USA and Germany\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eImpression Height\u003c\/th\u003e\n\u003ctd\u003e1\/32\" (0.75mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eShank Style\u003c\/th\u003e\n\u003ctd\u003eBent square shank (gooseneck)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMaterial\u003c\/th\u003e\n\u003ctd\u003eHeat-treated tool steel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eHallmark\u003c\/th\u003e\n\u003ctd\u003e12K\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eOrigin\u003c\/th\u003e\n\u003ctd\u003eUSA and Germany\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch3\u003eNotes\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMeasurement refers to the height of the impression, not the width.\u003c\/li\u003e\n\u003cli\u003eThis product is subject to California Proposition 65 warnings.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Otto Frei","offers":[{"title":"Default Title","offer_id":43584832078038,"sku":"155.912","price":33.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0609\/9832\/0342\/files\/12k-bent-square-shank-hallmark-stamp-132-0-75mm-impression-height-otto-frei.jpg?v=1719955898","url":"https:\/\/www.ottofrei.com\/ja\/products\/12k-bent-square-shank-hallmark-stamp-1-32-0-75mm-impression-height","provider":"Otto Frei","version":"1.0","type":"link"}
