How to Sharpen a Tuttle Tooth Saw

The teeth on a tuttle tooth saw should not be perfectly uniform. If you look closely at your saw, you'll notice two types of teeth: the cutters, which are longer, and the rakers, which are shorter. Cutters should be the same length as other cutters, and rakers should be the same length as other rakers. If you notice a long cutter or raker, you should file the tooth before you sharpen your saw.

Screwdriver
Clamps
Fine sandpaper
1/4-inch piece of steel
Saw file
Vise

Instructions

- 1
  Unscrew the handle from the blade with a screwdriver.
- 2
  Clamp the blade down to a flat work surface.
- 3
  Remove rust and debris from the blade with fine sandpaper, then unclamp the blade from the flat surface. Reinstall the handle and secure it in place with screws.
- 4
  Clamp a small piece of steel to a flat work surface. Hold the tuttle saw, with the teeth down, on top of the steel. Rock the saw back and forth on the steel, observing each cutter tooth of the saw. If one cutter tooth appears longer than the others, place the saw in a vise with the teeth up. Secure the saw in the vise. Use the diamond file to file the long cutter tooth bluntly until it looks the same as its neighbors.
- 5
  File the cutters in a beveled manner, applying three or four strokes of the file to each side of a cutter tooth.
- 6
  File rakers perpendicular to the blade and only inside the "V." Gently file the raker teeth as they file much quicker than cutters.
