{"product_id":"half-round-concave-jaw-bending-pliers-5-1-8-mirror-polished-german","title":"Otto Frei 5-1\/8\" Half-Round\/Concave Jaw Mirror Polished Bending Pliers","description":"\u003cp\u003eThe Otto Frei 5-1\/8\" (130mm) Half-Round\/Concave Jaw Mirror Polished Bending Pliers are precision hand tools designed for forming bezels and bending wire with controlled, consistent curves. One jaw is half-round and the other is concave — and when the jaws are brought together, the bend in the half-round jaw matches the concave jaw perfectly. The concave jaw measures 7mm while the half-round jaw measures 6mm, making this an ideal tool for fine, detailed metalwork at the bench.\u003c\/p\u003e\u003cp\u003eMade in Germany from carbon steel, these pliers offer superior strength compared to stainless steel alternatives. Carbon steel resists bending and misshaping under repeated use, ensuring long-term performance and reliability. The mirror-polished finish provides a refined working surface suited to professional jewelers and metalsmiths.\u003c\/p\u003e\u003cp\u003eAs with all carbon steel tools, some care is required: carbon steel will naturally develop a patina over time and can rust if left unprotected. Rust is easily addressed with light sandpaper. To protect your pliers, wipe them down with an oily rag after use or store them under one to prevent moisture exposure. Note that because carbon steel is rigid, it can fracture if subjected to shock from dropping or stress beyond its design limits — though such breakage is rare under normal bench use.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eHalf-round jaw on one side, concave jaw on the other for matched bending\u003c\/li\u003e\n\u003cli\u003eConcave jaw: 7mm; half-round jaw: 6mm\u003c\/li\u003e\n\u003cli\u003eJaws mate precisely — the half-round bend matches the concave profile when closed\u003c\/li\u003e\n\u003cli\u003eIdeal for forming bezels and bending wire\u003c\/li\u003e\n\u003cli\u003eMirror-polished finish for a refined, professional surface\u003c\/li\u003e\n\u003cli\u003eMade from carbon steel — stronger and more rigid than stainless steel\u003c\/li\u003e\n\u003cli\u003eMade in Germany\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eOverall Length\u003c\/th\u003e\n\u003ctd\u003e5-1\/8\" (130mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eJaw Style\u003c\/th\u003e\n\u003ctd\u003eHalf-round \/ Concave\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eConcave Jaw Width\u003c\/th\u003e\n\u003ctd\u003e7mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eHalf-Round Jaw Width\u003c\/th\u003e\n\u003ctd\u003e6mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMaterial\u003c\/th\u003e\n\u003ctd\u003eCarbon steel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFinish\u003c\/th\u003e\n\u003ctd\u003eMirror polished\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCountry of Origin\u003c\/th\u003e\n\u003ctd\u003eGermany\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch3\u003eNotes\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eCarbon steel will develop a natural patina over time; rust can be removed with light sandpaper.\u003c\/li\u003e\n\u003cli\u003eProtect from moisture by wiping with an oily rag after use or storing under one.\u003c\/li\u003e\n\u003cli\u003eCarbon steel is rigid and strong but can fracture under shock or stress beyond its design limits — handle with care to avoid dropping.\u003c\/li\u003e\n\u003cli\u003eAlso available in a heavier 6-1\/4\" version suitable for bending thicker ring shanks and materials — see part number 146.343.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Otto Frei","offers":[{"title":"Default Title","offer_id":43584303169750,"sku":"146.341","price":37.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0609\/9832\/0342\/files\/otto-frei-5-18-half-roundconcave-jaw-mirror-polished-bending-pliers-otto-frei-1.jpg?v=1719956285","url":"https:\/\/www.ottofrei.com\/products\/half-round-concave-jaw-bending-pliers-5-1-8-mirror-polished-german","provider":"Otto Frei","version":"1.0","type":"link"}
