The 357-36 is the replacement blade for the Silky Bigboy 2000, the curved version of Silky's big two-handed folding saw, with a 360 mm (14.2 in) blade.
Its extra-large teeth run 5.5 TPI (6.5 teeth per 30 mm), and the curve keeps them biting for the fastest limbing. 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.
