Designed for precision woodworking, it features a rapid cam lever tension system for effortless blade changes and a durable powder-coated finish that stands up to rigorous use. Perfect for professionals seeking efficiency, control, and style in one sleek tool. ## Description Designed to pull 50–60 pounds of tension on their blades, which makes it much stronger, and the blades vibrate less. 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 360°, with click stops every 45°. 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: Great saw - Great bit gear.
