The Knew Concepts Mk.IV 3" Heavy-Duty Jeweler's Saw Frame combines a cam lever tension system with 360° swivel blade clamps for maximum rigidity and cutting control. The upgraded Mk.IV design features a heavier frame that delivers up to 60 pounds of blade tension—two to three times greater than earlier generations—eliminating frame flex and dramatically improving accuracy on dense or hard materials. Machined from heat-treated aluminum, this frame is built for long-term professional use.
