Coping, fret and piercing saw blades are removable, and so they can be placed in the frame to cut on either the push stroke or the pull stroke, depending on which way the teeth are facing. However, because the blade is very thin, positioning it to cut on the push stroke could cause it to bend or even break.
Positioning the blade in the frame with the teeth facing back towards the handle ensures the saw cuts on the pull stroke, so the blade will be stretched taut in the frame when it’s pulled through the material.
As a result, when using one of these saws, you should only apply pressure to the saw when pulling it back towards you. On the push stroke, ease off, allowing the saw to simply move through the cut.
Starting your cut
Step 1 – Rest blade against material
Hold the saw parallel to the work surface and rest the teeth on the material.
Step 2 – Pull saw towards you
Slowly pull the saw back towards you, applying very little downward pressure, in one long, slow stroke.
