To change the blade of a coping saw you can loosen the tension by
turning the handle and then removing the blade. Or you can place the
far side of the frame against your bench and with the other hand push
with the handle. This will squeeze the frame releasing the pressure on
the blade. With your other hand slip the blade out from the spigots.
You can hold a coping saw in many different angles to cut at the angle
you need. This is what makes the coping saw so versatile. However
there are certain ways to use a coping saw to get the most out of it.
Because the blade is so small it can bend easily and heat up causing it to
weaken. To prevent this, take long strokes at an even pace, sawing too
fast will cause the blade to heat up. Just like with the handsaw you need
to keep the blade perpendicular to the work surface. If the blade is
difficult to move through the wood, it’s because the blade is binding (not
cutting perpendicular).
