Replacement blade for Shogun M-180R Japanese Ryoba Double Edged Pull Saw 180mm Length. The Shogun MC2424H is a 2 in 1 saw with one edge for Crosscutting (across the grain of the timber) and one edge for Rip cutting (parallel to the grain of the timber). The 2 edges are clearly marked for the different functions with differing tooth types to maximise efficiency for each function. This saw is a true all round work horse for carpenters, joiners and woodworking hobbyists alike. It is equally at home in softwoods, hardwoods, green or oily timbers. Japanese saws are made from very high quality steel with hard and long lasting teeth. With a little care lt will last for many years of daily use. They should not be considered disposable like the Western equivalents.
