Description
These American made fretsaws are a favorite of fine woodworkers, jewelry makers, artisans, metal-smiths, luthiers, model builders, serious home hobbyists and “makers” of all types.Woodworkers find these handsaws excel at cutting out the waste on hand cut dovetails, for fine scroll / curved cutting and for general small scale sawing tasks.
An innovative truss structure creates a very rigid frame without adding a lot of weight.The light weight makes them comfortable and easy to handle, so you can cut with improved accuracy. The unique blade mounting system lets the blade seat firmly at 90 degrees for straight-ahead cutting and also rotates, angling the blade, which provides the frame’s back more clearance (useful when sawing the baseline of a dovetail).
The amount of blade tension is easily adjusted with a large knurled knob, while a unique cam lets you apply or release blade tension instantly with the simple flip of a lever.
The 5″ fret saw is the most popular size for removing dovetail waste.

Mark 5 – new upgraded replacement for the Mark 3
Mark 5 saws are also made from lightweight anodized aluminum with the triangular truss design originally used in from the Mark 4 saws. The tension is about 10% higher that the Mark 3 saws, but the weight is still less than the Mark 4 saws. They also have upgraded the blade clamps for better grip.
