Genuine replacement blade for the Silky BigBoy 2000 356-36 folding saw. To replace the BigBoy 2000 blade, undo the single black pivot bolt using a wide flat screwdriver, remove the old blade by gently sliding off the handle, insert your new one and re-tighten the bolt, and you are back in business. The Silky BigBoy 356-36 replacement blade features a rust-resistant, hard chrome-plated, taper-ground blade with an impulse-hardened non-set tooth design for greater cutting efficiency. The precision-ground, razor-sharp teeth with four cutting angles provide fast, clean and extremely smooth cutting action.
