The 353-36 is the fine-tooth replacement blade for the Silky Bigboy 360, the big two-handed folding saw with a 360 mm (14.2 in) blade.
Its teeth run 11 TPI (13 teeth per 30 mm), for clean carpentry cuts and hardwood. Like every Bigboy blade it's chrome plated and taper ground so it won't bind, with non-set, impulse-hardened teeth. When the teeth dull, fit a new blade and keep your handle.
Katsuji Miyawaki founded Silky in 1919 in Kishi, Japan, under the brand Tamakitsune, and all of its saws took the Silky name in 1983. The company is now headed by Uichi Miyawaki, and its saws are made in Ono, Japan.
