What reading level is Tools And Machines book?
To quickly assess the difficulty of the text, read a short excerpt:
We recognize that any notched or serrated cutting- blade is a saw. The origin of the saw is lost in the long-forgotten centuries, yet we may feel sure that the THE SAW AND THE SAWMILL H5 saw is quite as old as the knife. The ragged edge of an oyster-shell or the curious weapon carried by the saw- fish may have first suggested the saw. However it may have been originated, we readily see that it is one of the most ancient and most useful of all the tools.
We take up a common carpenter's saw and e...xamine its edge, and see that it consists of a series of serra- tions or notches, all of the same size and all having a little cutting-edge on each side. Looking along the edge we see that each tooth is bent slightly to the right or left. It is said to be " set " in that position, every alternate tooth being set to the right and the others set to the left. Each tooth is a tool, and when the saw is used each tooth acts as a tiny cutting-chisel that chips out the small bits of wood we call sawdust.
