3rd Hand Saw Guard Tools and accessories that we think can improve jobsite safety always stand out. California contractor Jack Tracy's creation, called the 3rd Hand, is a blade-guard control lever designed to fit a number of wormdrive saws. It can lead to safer operation of circ saws. When installed on a wormdrive saw, the operator uses the thumb on his trigger-finger hand to lift the guard out of the way for rips, cross-cuts, and steep angle cuts where guards typically get hung up. This frees the other hand to guide and control the saw through the cut instead of reaching to lift the guard. Tracy developed the 3rd Hand under the watchful eye of an OSHA inspector. 805.445.1066. www.the3rdhand.com.
