Knew Concepts Fret Saws are a striking departure from the traditional brand saw design. Engineered and manufactured right here in the US, they’re made to be lightweight and easy to control. Knew Concepts fret saws are designed to be feature rich, making them faster to set up and easier to handle than any other fret saw you’ve used before. These saws are very stable and allow minimal blade deflection while in use.

Right from initial blade installation you’ll appreciate the convenience of the quick-release camming tension level and fine adjustment screw. This lets you switch from blade to blade without needing to re-tension. Just slide the blade into the receiver and tighten the knob. Then add tension with the lever and you’re ready to cut.

The spring-loaded blade clamps allow for easy 45° rotation in either direction. This makes off-axis cuts a breeze, letting you use either hand! You’ll have unparalleled control and access to even the most demanding of cuts.

These saws accept any standard 5-1/8” plain-ended blades, such as our FSB-001 PEGAS #7 Blade. There is even a blade length gauge built right into the spine of the saw, so that you’ll have an easy reference measurement for what will fit!

Work with more efficiency and confidence without sacrificing the quality of your craftsmanship. Now that’s what we call progress!

Models:

The 101-620 (Mk.V 3CS) and the 101-621 (Mk. V 5CS) are regular-strength models, with standard 1/8” thick anodized aluminum spines. They only differ in their depth of cut. They’re meant for the sort of average use that you’d expect a fret saw to perform.

The 101-622 (Mk.IV-5CS) and the 101-623 (Mk.IV-8CS) have more robust 3/16” thick spines. Additionally, the Mk. IV models allow the blade to rotate through 360° instead of only rotating 45° each direction. These are serious fret saws which are meant for serious business. You’ll really appreciate the thicker spine on the 8” deep model. These IV-series saws will easily keep up with most any task you’d ask them to perform, and then some!

  • Modern construction, making the saw extremely light in weight
  • Doesn't sacrifice stability or add to blade deflection

Customer Reviews (4.4 / 5 · 5 reviews)

Joshua Q. ★★★★★

Swapped out my old wooden saw for this and the difference in control is night and day—the lightweight frame lets me make those tight curves without the tool fighting me. Setup took a minute to get used to, but once the blade tension is dialed in, it tracks beautifully.

William T. ★★★★★

The aluminum frame makes it feel featherlight in my hand, and the thumb screw adjusts tension smoothly without any fumbling. I was skeptical about the price, but the control I get on tight curves is worth every penny.

Christopher C. ★★★★★

The blade tensioning mechanism locks down so precisely that I get zero drift on tight curves, and the whole frame feels balanced enough for hour-long sessions without wrist fatigue. Honestly, the US machining tolerances are obvious the second you pick it up.
