There are many kinds of saws.

  • Chainsaws

    The chains of mechanical chainsaws need to be sharpened often to reduce the engine’s stress and prevent the chain from burning. Each tooth is sharpened by hand using a file with a guide.

  • Circular or Radial Blades

    Several tools with various uses are equipped with circular or radial blades. These include table saws, circular saws, miter saws, and brush cutters, among others.

    These blades usually have between 24 and 80 teeth, which need to be sharpened individually. Each tooth must have exactly the same sharpening to maintain consistent depth. The angle of the tooth surface is also crucial as it prevents the blade from vibrating and oscillating from side to side.

    They are made of tungsten carbide, molybdenum carbide, or high-speed steel alloys, which are very hard and require specific machinery and precise calibration.

    It is possible to sharpen blades that are not made of carbide but softer steel. They require the same process but with different tools.

  • Circular saw or radial saw

    This type of portable mechanical saw is designed to cut various materials on-site. It is equipped with a round blade with teeth on its perimeter, similar to a panel saw or mechanical miter saw. For sharpening these blades, see the section on radial or circular saw blades.

  • Crosscut Saws or Two-man Saws

    This saw is rarely used nowadays in Canada. It is used for felling and cutting trees. Like all saws, the teeth have a particular cutting angle to reduce effort while maintaining an efficient cutting pace.

  • Frame Saws or Bucksaws

    Frame saws are mainly used by hikers and campers in remote areas. Giving them a good sharpening before heading out ensures their effectiveness, if they don’t cut well, they become nothing more than additional weight and are unusable.

  • Hand Saws

    Hand saws come in various types depending on their dimensions, shapes, and teeth configurations, tailored to different cutting needs. Some are for rip cuts, others for crosscuts. There are even hand saws that cut on the pull stroke instead of the push stroke, like Japanese finish saws. Their sharpening process involves various combinations of different angles.

  • Hole saw or hole cutter

    This saw could also be called a drill bit as it is used to make holes. It is usually paired with a drill bit that guides the bell-shaped blade along its axis. Keeping it well-sharpened reduces friction and material burning.

  • Miter saw

    Miter saws are used in woodworking and carpentry to make precise angle cuts. They can be mechanical or manual and are mounted on a base with guides. Manual versions are a type of hand saw, while motorized versions have a large diameter circular saw blade. To prevent splintering or fraying of the wood, the blade must be kept sharp

  • Pruning Saws

    These saws are mounted at the end of long fiberglass or aluminum poles and are used to cut tree branches. They are designed to be very sharp as they need to cut quickly with minimal pressure.
