This plain, round profile triblet from Durston has a working length of 260mm (10.25"), with a total length of 362mm (14.25") including handle. This triblet has a diameter of 5mm at the thinnest point of the blade, and a diameter of 20mm at the widest point. Used for forming or re-shaping metal, triblets are particularly useful when working with rings. They can be used to form a ring or a circular bezel to a chosen approximate size, to re-size an existing ring, or to correct the shape of a misshapen ring. This unmarked, solid triblet is made from hardened and ground steel, and should be kept clean and polished to avoid any marks which may be transferred onto the surface of your metal. It can be hand held or secured by the handle into a bench vice. Securing at any other point will mark or damage the surface of the triblet and transfer onto the surface of your metal.
