A backsaw is a saw that features a reinforced back along the top of its blade. This reinforcement stiffens the blade, enabling straight cuts.
Where it fits
- Some tenon-style backsaws are intended for small-section timber and miter-guide sawing. Choose the saw for the material and cut rather than assuming every backsaw has the same tooth pattern.
Parts to compare
- When selecting a generic backsaw, compare the handle and reinforced back. Some tenon saws have hardpoint teeth, so check for this feature on the blade you choose.
Choosing teeth
- Select tooth count for the stock and finish. TPI means teeth per inch; it does not describe the length of the blade.
Care and limits
- Do not twist a backsaw blade to break away waste, as this can damage or break the blade. Store the saw so that other tools cannot damage its teeth.
