When starting out, it is easy to saw a piece of lumber; however, when sawing deeply, however, the blade binds and it is difficult to proceed. Rollingsaw solves this problem, with a small hinge which moves whenever a person takes a sawing action, opening the crevice for the blade to enter. When pushing it forward, the hinge is pulled back and opens the crack (the hinge gets a little bigger on the sides at this point). When pulling, because of the open crevice, there’s no jam, thus providing a smooth cut.
