{"product_id":"fretz-f9-convex-concave-stake","title":"Fretz F-9 Convex\/Concave Stake","description":"\u003cp\u003eThe Fretz F-9 Convex\/Concave Stake is a miniature silversmiths forming stake machined from hardened stainless steel with highly polished working surfaces. Designed for jewelers and metalsmiths, it performs the same functions as larger traditional stakes — forming bezels, making hollow rings, and general smithing work — scaled down for precise, small-scale applications. The convex end is suited for general forming tasks, while the concave end is purpose-built for shaping concave curves on bracelets and cylinders. As with any forming tool, the stake can be modified to suit custom applications.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eHardened stainless steel construction for durability and long-term performance\u003c\/li\u003e\n\u003cli\u003eHighly polished working surfaces minimize surface marks during forming\u003c\/li\u003e\n\u003cli\u003eConvex end for general forming, hollow rings, and bezel work\u003c\/li\u003e\n\u003cli\u003eConcave end for shaping concave profiles on bracelets and cylinders\u003c\/li\u003e\n\u003cli\u003eScaled for small-scale and detailed smithing work\u003c\/li\u003e\n\u003cli\u003eCan be modified for custom forming applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eSurface Dimensions\u003c\/th\u003e\n\u003ctd\u003e77 mm × 13 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMaterial\u003c\/th\u003e\n\u003ctd\u003eHardened stainless steel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSurface Finish\u003c\/th\u003e\n\u003ctd\u003eHighly polished\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCountry of Origin\u003c\/th\u003e\n\u003ctd\u003eVietnam\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e","brand":"Fretz","offers":[{"title":"Default Title","offer_id":43580977381590,"sku":"112.639","price":71.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0609\/9832\/0342\/files\/fretz-f-9-convexconcave-stake-otto-frei.jpg?v=1719957854","url":"https:\/\/www.ottofrei.com\/products\/fretz-f9-convex-concave-stake","provider":"Otto Frei","version":"1.0","type":"link"}
