A jeweler's saw frame holds and tensions the blade for piercing and cutting at the bench, and the depth of its throat sets how far in from an edge you can cut. The Grobet USA jeweler's saw frame was designed and patented in Switzerland and was a revolutionary advancement when it was introduced in the late 20th century. Compared to standard saw frames of the era, these frames are lightweight and well balanced, with an ergonomically designed cushioned handle that helps reduce hand fatigue and allows greater dexterity during detailed work.
The standout improvement is the patented blade lock design, which eases blade insertion, maintains perfect alignment, eliminates wobble, and significantly reduces blade breakage. The frames are precision made from the highest quality spring steel with a non-glare finish, built for professional daily use, and the set screws can be positioned on either the left or right side of the frame to suit your working preference. Both the Adjustable and the Fixed frame carry a 2¾" (70 mm) deep throat, giving ample clearance for a wide range of cutting tasks.
