Available in 3\" and 5\" throat depths, the Mk.V features an upgraded triangulated truss design — the same geometry that makes the Mk.IV frames exceptionally rigid — delivering a major strength improvement over the older Mk.III design. The redesigned blade clamps are longer for improved grip, include witness holes so you can confirm the blade is fully seated, and allow sawdust to fall clear of the clamping surfaces for consistent, solid blade retention from session to session.\u003c\/p\u003e\u003cp\u003eThe swiveling blade clamps rotate 45° left or right — 90° total range — so you can swing the rear of the frame out of the way and cut into areas previously out of reach. Three preset detents at 0°, 45° left, and 45° right make it easy to return to the most common working angles quickly and repeatably. The lever-tension system lets you dial in your preferred blade tension once, then release and reapply it instantly with a single motion — no time-consuming re-adjustment between cuts.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eLever-tension system\u003c\/strong\u003e — set tension once, then release and reapply with a single lever motion\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSwivel blade clamps\u003c\/strong\u003e — rotate 45° left or right (90° total range) for adjustable blade direction\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePreset detents\u003c\/strong\u003e at 0°, 45° left, and 45° right for precise, repeatable cutting angles\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWitness holes\u003c\/strong\u003e in clamps let you visually confirm blade seating and allow sawdust to clear\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended clamp length\u003c\/strong\u003e provides more contact surface for improved blade grip\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTriangulated truss frame design\u003c\/strong\u003e — the same geometry used in the Mk.IV for maximum rigidity\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReversible clamp knobs\u003c\/strong\u003e — switch sides for left- or right-handed operation\u003c\/li\u003e\n\u003cli\u003eLightweight aluminum construction reduces fatigue during long bench sessions\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eFrame Generation\u003c\/th\u003e\n\u003ctd\u003eMk.V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFrame Material\u003c\/th\u003e\n\u003ctd\u003eAluminum\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTension System\u003c\/th\u003e\n\u003ctd\u003eLever tension\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eBlade Clamp Type\u003c\/th\u003e\n\u003ctd\u003eSwivel blade clamps with witness holes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSwivel Range\u003c\/th\u003e\n\u003ctd\u003e90° total (45° left, 45° right)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePreset Detent Positions\u003c\/th\u003e\n\u003ctd\u003e0°, 45° left, 45° right\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eBlade Compatibility\u003c\/th\u003e\n\u003ctd\u003eStandard 5-1\/8\" unpinned jeweler's saw blades\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eAvailable Throat Depths\u003c\/th\u003e\n\u003ctd\u003e3\" (76 mm) and 5\" (127 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch3\u003eAvailable Options\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003ePart #\u003c\/th\u003e\n\u003cth\u003eThroat Depth\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e149.643\u003c\/td\u003e\n\u003ctd\u003e3\" (76 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e149.645\u003c\/td\u003e\n\u003ctd\u003e5\" (127 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch3\u003eWhat's Included\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eKnew Concepts Mk.V lever-tension saw frame with swivel blade clamps (choose 3\" or 5\" throat depth)\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eNotes\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eKeep clamp faces clean and aligned for secure blade grip.\u003c\/li\u003e\n\u003cli\u003eIf the lever resists closing, slightly reduce tension using the fine adjustment knob.\u003c\/li\u003e\n\u003cli\u003eConfirm the blade is straight through both clamps before sawing.\u003c\/li\u003e\n\u003cli\u003eStore with blade tension relaxed if the frame will not be used for an extended period.\u003c\/li\u003e\n\u003cli\u003eThis product is subject to California Proposition 65 warnings.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Knew Concepts","offers":[{"title":"3\" (76mm)","offer_id":43692827672790,"sku":"149.643","price":114.0,"currency_code":"USD","in_stock":true},{"title":"5\" (127mm)","offer_id":43692827705558,"sku":"149.645","price":119.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0609\/9832\/0342\/files\/knew-concepts-jewelers-precision-aluminum-sawframes-with-cam-tension-and-asd-otto-frei.jpg?v=1719955512","url":"https:\/\/www.ottofrei.com\/products\/knew-concepts-mkv-lever-tension-swivel-blade-clamp-saw-frames-3-5-inch","provider":"Otto Frei","version":"1.0","type":"link"}
