Japanese Folding Saw for Gardening  

Gardening is an exercise in optimism. Sometimes, it is a triumph of hope over experience.

The Japanese folding saw used for gardening is not one I would tackle for many reasons.

  1. The saw's blade has a tooth shape which is quite complex:
    1. The blade will probably have multiple angles cut into each individual tooth, and these can change across the saw's length. A 3rd or 4th angle in a single tooth is not uncommon.

    2. At least the Silky brand saws have a shape where the sides of the tooth are not straight from base to tip. The center of the tooth is thinner than the tip, and the base of the tooth is between those two.

  2. Additionally, it is common for these saw blades to have impulse hardened teeth, making it virtually impossible to use a file to re-sharpen them. Even dimond cards will not work.

    This also can make the teeth brittle, so re-sharpening is difficult.

If you do choose to sharpen these saws, be sure you also understand what the set needs to be. It is common for there to be no set; instead the changing width of the teeth accomplishes the same objective.

Don Williams at The Barn at White Run was successful using a diamond-shaped, aluminum oxide, “India” stone. Whilst most simply replace the blade, resharpening a blade is apparently possible.
