The only difference between these saws and their larger brothers is in the blade and handle length. Each has a 180mm-long blade which is perfect for getting into a tight space or fine cabinet work. The reduced size also reduces cost which makes these good to try before committing to the larger saws. All mini Japanese Saws come with the modern EVA-GRIP handle that moulds to user grips more comfortably over longer periods.
There are four versions available - the Dozuki saws with spines that provide extra rigidity have 0.3mm blade thicknesses while the other two require thicker 0.5mm blades. All come with a standard 16TPI tooth set on one side for cross and end-grain cutting except the finer Dozuki which is 25TPI for extremely fine detail work such as cutting dovetails on thin materials. The Ryoba's second edge has 8TPI for ripping timbers.
The RS-290 and 293 has a leading tooth set on the front of the blade to perform plunge cuts into timber.
