A bent or broken tooth on a Japanese pull-style saw can extend out beyond the kerf and drag or catch with each stroke, making the saw difficult or impossible to use. To bring the damaged tooth back into alignment, gently run the side of the blade over a medium-grit diamond stone (1,000-grit works well), applying even pressure with a block of wood. A few easy strokes on each side of the saw is all it takes to flatten the trouble spot. A saw can be repaired this way many times before it has to be retired.
