## Overview

The Knew Concepts 5” Mk.IV Heavy Duty Fret Saw features a unique 360° swivel blade clamp with click stops, a cam lever tension system for rapid blade changes, and a robust frame designed to hold 50-60 pounds of tension. Its powder-coated red finish ensures durability, while the included 15 TPI #7 skip-tooth blade delivers smooth, precise cuts. Perfect for professional woodworkers seeking efficiency and control in detailed fretwork and dovetail joinery.

## Description

Designed to pull 50–60 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 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.

Review: Excellent tool, modern tech to improve on traditional practices - Sure, it's pricey, but I didn't realize how much this would make a difference over a traditional coping saw. The thinness of the blade, pitch of the teeth, rigidity of the frame and cut angle control, all come together into a truly functional tool. After seeing this used and recommended by various woodworking channels on YouTube, I got on the bandwagon, and glad I did. For the main purposes of improving my hand cut dovetail results, this saw makes the process much more efficient and enjoyable. After using the dovetail saw to make the cuts for the tails and pins, this tool makes it much easier to clear out the bulk of the waste material, allowing me to get extremely close to my marking lines, and minimizing the amount of clean up chiseling that needs to be done. The thinness of the blade along with the control of the blade angle allowed me to easily get into the dovetail cut and tightly turn to cut out the waste between tails and pins. The frame and blade clamping/tightening technology hold the blade firmly in place and allow it to remain rigid throughout the process. Results were satisfying after just getting the saw in my hands. I may even use this someday as an actual fret saw for some guitar building...
Review: Highly Recommended - Fantastic saw. Holds blade steady and is so very easy to use.

Fantastic saw. Holds blade steady and is so very easy to use.

### ⭐⭐⭐⭐⭐ It Is a Great Tool
*by J***P on April 5, 2025*

Unlike other reviewers I feel that the price is reasonable. It is a great tool, and great tools cost more than the others -- that's how this works. Having tested it out for a few cuts, it works as advertised. It is amazing to me how tight corners can be cut with it compared to a standard coping saw. Easy to use. Fairly light-weight, even though it looks heavier than it is. Well-balanced. Also, while I have read/watched several other reviews of this saw mention that the handle is sub-standard for their tastes, this handle seems perfectly fine for me, but I don't have large paws. The tensioning and angling mechanisms were intuitive for me. I have no complaints, and cannot think of anything I would change about the design yet. I bought this with my own money and no one pressured me to say such nice things about it.
