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.
