Ripsaw

A ripsaw (or rip saw) is a wood saw that is specially designed for making a rip cut, a cut made parallel to the direction of the wood grain.

The cutting edge of each tooth has a flat front edge and it is angled backward by about 8°, in contrast to a crosscut saw, which has teeth angled backward by about 15°.

This feature enables the orthogonal cutting edge to efficiently transport wood-chips from the kerf, allowing subsequent teeth to perform a more effective cut.

[citation needed] Ripsaws typically have 4–10 teeth per inch, making them relatively coarse.

Some sawmills also use crosscut saws to cut boards and planks to length.
