Nail Biter Freud recently introduced a spaceage- looking Deck and Framing Blade that can cut through nails without slowing down. In fact, when it cuts through a nail, you don't even hear the familiar high-pitched whine that usually means you've just wasted another blade. According to the manufacturer, the teeth are made from a specially formulated carbide that is more resilient than conventional C-4 carbide and less likely to chip. The 71/4-inch thinkerf blade has multiple slots, designed to keep the blade cool and reduce run out. A "reverse tooth" reportedly clears chips from the kerf, adding to the blade's ability to cut fast through pressuretreated, green, and wet or frozen framing lumber.
