Woodworkers find these handsaws excel at cutting\n out the waste on hand cut dovetails, for fine scroll \/ curved cutting and for general small scale sawing tasks.\u003c\/p\u003e\n\n\u003cp\u003eAn innovative truss structure creates a very rigid frame without adding a lot of weight.  The light weight makes\n them comfortable and easy to handle, so you can cut with improved accuracy. The unique blade mounting system lets\n the blade seat firmly at 90 degrees for straight-ahead cutting and also rotates, angling the blade, which provides\n the frame's back more clearance (useful when sawing the baseline of a dovetail).\u003c\/p\u003e\n \n\u003cp\u003e The amount of blade tension is easily adjusted with a large knurled knob, while a unique cam lets you apply or\n release blade tension instantly with the simple flip of a lever.\u003c\/p\u003e\n\n\u003cp\u003eThe \u003cstrong\u003e5\" fret saw\u003c\/strong\u003e is the most popular size for removing dovetail waste.\u003c\/p\u003e\n \n\u003ch4\u003eWhat's the difference between Mark 3 (Mk3), Mark 4 (Mk4) \u0026amp; Mark 5(Mk5)  saws?\u003c\/h4\u003e\n \n\u003ch5\u003eMark 3 - \u003ci\u003enow discontinued and available while supplies last\u003c\/i\u003e\n\u003c\/h5\u003e \n\n\u003cp\u003eMark 3 saws are from thin lightweight 1\/8\" thick anodized aluminum.
