Knew Concepts Mk.IV 5" HD Saw Frame with Lever Tension

A 5" heavy duty jeweler's saw frame for piercing and cutting at the bench, tensioned by cam lever. The Knew Concepts Mk.IV 5" Heavy Duty Jewelers Saw Frame delivers a dramatic leap in blade tension over standard frames, up to 60 pounds of tension, which is 2–3 times greater than other Knew Concepts 5" jewelers saw frames. That extraordinary tension eliminates flex in the frame, allowing for significantly improved cutting accuracy and control. Whether you are piercing intricate designs or cutting through heavier stock, the rigidity of this frame keeps your blade on line.

Because of the increased structural strength of the Mk.IV Heavy Duty frames, Cam Lever Tension is the only available tensioning method; traditional screw tension simply cannot generate the force required for these frames. The cam lever mechanism makes blade changes fast and consistent, locking in that high tension reliably every time.

• Up to 60 pounds of blade tension, 2–3 times more than standard Knew Concepts 5" saw frames
