The traditional all-purpose workhorse of Japanese carpenters—dual-edged blade for both crosscuts and rips.
Z-Saw S-250 Double-Edge Ryoba Saw and Replacement Blade
If you could take only one Japanese pull saw to a deserted island, it would have to be the Ryoba. With a rip blade on one edge and a crosscut blade on the other, you would have a shelter built in very short order. It cuts solid wood, plywood, veneered wood, engineered wood and more. Like most Japanese saws, it cuts on the pull stroke, putting the blade in tension for an exceptionally fine, straight cut. Since the kerf is narrow, very little energy is required.
