Editing Ripsaw (section)

==Design==
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°.<ref name=Lye71>{{cite book|last1=Lye|first1=P.F.|title=Woodwork theory|date=1971|publisher=Thomas Nelson |location=London |isbn=9780174443209 |page=23 |edition=Metric |url=https://books.google.com/books?id=d4VVOjz1GpgC&q=%22rip+saw%22&pg=PA23 |access-date=22 October 2015}}</ref> 

With the "rip" tooth pattern, the edges are sharpened at right angles to the cutting plane, forming [[chisel]]-like cutting surfaces, whereas  crosscut teeth are sharpened at an angle, so that each tooth has a [[knife]]-like cutting point in contact with the wood.<ref name=Lye71 /> This design keeps the saw from following grain lines, which could curve the path of the saw: by acting like a chisel, the saw can more easily cut across deviating grain lines, which is necessary if a straight cut is to be achieved. This feature enables the [[Orthogonality|orthogonal]] cutting edge to efficiently transport wood-chips from the [[kerf]], allowing subsequent teeth to perform a more effective cut. 

It is possible to see this material removal mechanism in action by analyzing frame by frame footage of the cutting process.{{cn|date=July 2019}} Ripsaws typically have 4–10 teeth per inch, making them relatively coarse.{{cn|date=July 2019}}
