| − | In the diagram, the red circles show the pivot point of the blade, and the blade in the 90 degree position and 45 degree position. Both 90 and 45 saw cuts would finish the piece off to the same length, but it is clear that a different position of the saw blade compared to the profile is required. This is demonstrated by the dimension x.
