| 1. A hand-held circular saw with an integrated dust collection system comprising:
an upper blade guard for protecting a user from a saw blade, the upper blade guard configured with a front region and a back
region, the front region including a hollow channel to control the pathway of dust and debris;
a dust collection system, having a first end and a second end, located within the front region of the upper blade guard allowing
dust and debris to be directed away from the user, the first end of the dust collection system connects to the front region
of the upper blade guard; and
a lip on the hollow channel allowing the second end of the dust collection system to be aligned with the hollow channel disposed
within the front region of the upper blade guard,
wherein the dust collection system includes a variable dust chute, the dust chute being rotatable about an axis parallel to
a plane of the saw blade thereby allowing the dust chute to rotate between a first position and a second position, and
wherein, in the first position the dust chute directs dust and debris away from the user and in the second position the dust
chute directs dust and debris to the hollow channel.
