These are the original Knew Concepts Saw Frames, also called Fret Saws, with a screw tension. Knew Concepts calls this their economy model. It provides extremely precise blade tensioning simply by turning the knurled tension nut at the top of the frame.
Saw frame flex in the basic jewelers saw frame can contribute to blade breakage. With the advanced design of the Knew Concept Sawframe, saw frame flex is minimized, reducing sawblade breakage and maximizing sawblade life. The Knew Concepts Jewelers Precision Saw Frame is designed for maximum rigidity and comfort.

Even the smallest detail of the Knew Concept Sawframe has been thought out:
- The knurled gold tone blade holders on either end are for making quick and easy sawblade changes
- The lightweight aluminum frame makes the Knew Concept Sawframe the lightest on the market, an important factor for jewelers who spend a lot of time with a sawframe in hand.
- The frame is made of heat treated aluminum and is designed to eliminate flex while being the lightest sawframe on the market today. Because the rigid frame will not flex, the traditional method of tensioning the frame against your chest to fit new sawblades is not used.
