Abstract
A metal cutting circular saw is provided with an upper blade guard which includes a first sight window disposed in a first side surface and disposed in a plane angularly offset from a plane of the blade. The upper blade guard also includes a second sight window disposed in the second side surface of the upper blade guard. A light window is disposed in a front portion of the perimeter outer surface of the upper blade guard. The upper blade guard is made from metal and the first and second sight windows and the light window are integrally formed as a one-piece member. The saw shoe and lower blade guard are configured to minimize chip spray from contacting a user.
