Tools make work easier and safer. While you probably don't look at saw blades with the same level of gadget lust as you do a smartphone -- the latest additions to DeWalt's cutting line literally pull themselves through a piece of lumber.
Engineered woods like particle board and plywood certainly make buildings stronger, but at the same time they're harder on cutting blades. Shortening their lifespans and making it more difficult to control a saw. So DeWalt's new Precision Framing Saw Blade (£8) not only includes extra tungsten carbide teeth covered with a teflon-like coating -- which work to literally pull a circular saw through a piece of wood -- it's also got unique resin filled expansion slots which dampen vibrations that would normally be absorbed by a carpenter's arm. Making the job quicker and safer. It also begs the question: How much wood would a woodchuck chuck if a woodchuck were equipped with one of DeWalt's new blades? [DeWalt via Popular Science]
