| KNEW CONCEPTS 5" MARK IV HEAVY DUTY HAND SAWS with CAM LEVER TENSION
Knew Concepts saw frames were designed to address the needs of the hand-sawing jeweler and craftpersons.
| So, What do these New Mark IV Saw Frames Offer?
Saw frame flex is a big culprit in breaking sawblades. The Mark IV frames are designed to pull 50–60 pounds of tension on their blades, which makes them much stronger and the blades vibrate less than than the Mark 3 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, with a laser engraved logo and is extremely scratch and damage resistant. That rigidity also translates into better control over your sawblade.
Red saw frame. Why red? A recent study published in Science magazine suggests color has an effect on cognitive tasks. Data indicates the color red promotes better accuracy when performing tasks. Sawing is definitely an area you want accuracy.
Efficiency with the Cam Lever Tension
The saw frame is not adjustable. It is designed for use with standard length jewelers' sawblades. This eliminates and adjusting or "fiddling" with loose frames when you are trying to fit a blade. This saw frame features the amazing Cam Lever. The Cam Lever allows for the quick tensioning of sawblades. You just insert a sawblade and tighten, then use the Tension Screw to "pre-tension" the blade. Then by flipping the Cam Lever over 180deg., the blade gets a locked into its final tension position. Now anytime you need to replace an blade, just release the Cam Lever, change the blade and reset the Cam Lever. You are ready to go. No need to readjust the tension. Saves you tons of time and aggravation.
