Knew Concepts Mk.IV Aluminum Swivel Fret Saws

With thicker, stiffer frames than the Mk.III-series saws, these fret saws let you apply even greater blade tension, helpful when using thick blades or when making precise cuts in denser hardwoods or in brittle materials that are prone to chipping. Each uses the same innovative blade holder and tension mechanism, which makes changing and tightening blades fast and easy.
