The Silky Katanaboy is the largest Japanese folding saw Silky makes, a two-handed pull saw for logs, big limbs and timber where you might otherwise reach for a chainsaw.
Three sizes. The 550 has a 550 mm (21.6 in) blade and cuts logs up to 11 in. The 700 has a 700 mm (27.5 in) blade and cuts logs up to 14 in. The 1000 has a 1000 mm (39.4 in) blade with progressive teeth that get coarser toward the tip. The 550 and 700 blades are nickel plated, taper ground and resharpenable, and a security screw keeps the blade from opening or closing by accident.
The 550 and 700 come in a synthetic fiber case with a pocket for a spare blade; the 1000 comes with a canvas case. Replacement blades are stocked for each size, plus 500 mm and 650 mm blades for the Katanaboy 500 and 650.
