A new circular saw called the Crocodile was named on Popular Mechanics’ "Top 13 New Tools for 2008" from the National Hardware Show. This tool may be small enough to hold in one hand, but it still packs a punch. It is the first circular saw designed to cut wood, drywall, plastic and metal. This diversity makes the Crocodile a pretty handy tool on a remodeling job. Not to mention, it has a really cool name.
