Second-Class Saw Cuts
This class of cut is used when accuracy is important,
such as when sawing the cheeks of a tenon or a lapped
dovetail joint inside a case piece. The results of your
cut will be buried in the mortise or in the dovetail socket,
so appearance isn't of primary importance.
Begin by marking your cut with a knife all around your
work. Then, at the corner where you will begin your
cut, place a chisel in your knife line with the bevel
of the chisel facing the waste. Press the chisel into
the work, remove the chisel and then come back and pare
a triangle of waste that leads up to that corner.
Now place your saw in this notch and begin cutting.
The notch ensures you begin the cut correctly, which
is the most difficult part of sawing.

Second class sawing: Place the bevel of the chisel
toward the waste and press the tool in. A 1/16"
or 3/32" depth of cut will do.
