Wooden Nail Saw: Kugihiki Noko Giri (Nail Saws) are used to trim wooden nails and plugs flush with the surface of your work. The blade is quite thin and flexible, so when in use, it can be bent with a portion of the blade held flat against the work surface. The teeth have no set to eliminate scratching your work. Kugihiki Noko Giri are also great for cutting a very fine, thin kerf in small work.
