Coping saws are used for cutting a range of woods and are very useful for cutting unusual shapes or
curves. Using a coping saw takes some time and practice as it can be difficult to control the direction of
the blade. The blade shown in the picture is approx. 150mm long and is held in place by slotted pins
which are placed on either side of the coping saw’s frame. The student below demonstrates the use of the
coping saw in the school workshop.

The tenon saw is particular useful for cutting straight lines in wood. The heavy back gives the saw its
weight, which is useful when sawing the wood. The weight of the saw along with the forward sawing
motion allows the saw to cut through woods relatively easily.
The pupil on the right shows the proper way of holding the tenon saw. The saw has to be held in the hand
carefully. The index finger must point in the direction of sawing and it also helps to support the whole saw
as it moves. The wood being cut must be held in a bench hook which is clamped into the vice.
