Knew Concepts Fret Saw MK. IV - 5inMade in USA, these fret saws are designed for quickly cutting waste from hand-cut dovetails. Their innovative truss-like frames are light-weight and far easier to use than their predecessors - the traditional jewelers fret saws.
This new "heavy duty" version is designed to pull 50 to 60 pounds of tension on their
blades, which makes it much stronger, and the blades vibrate less than
our Mk3 saws. They are are also thicker and slightly heavier, closer to
the weight of a traditional saw, but still lighter. The saw is
powder-coated red, with a laser engraved logo and is extremely scratch
and damage resistant.
The Cam Lever Tension is designed for rapid, repetitive
blade changes (when piercing for example). The tension does not change
when re-setting the blade. Simply flip the lever forward to release
tension, re-position and clamp the blade, and flip the lever to the
rear, and you are sawing.
The Swivel Blade Clamps can rotate the saw blade a full 360Â°, with click stops every 45Â°
