Silky 730-33 13" (330mm) Silky Gunfighter Saw is a new lightweight saw with a special quick-change design for replacing the blade when its worn out. The blade features progressive tooth sizing which starts finer near the handle and increases to a more aggressive tooth size near the tip. When you feel like its time for a new blade, all have to do is lift up on the trigger at the top of the handle to release the blade.
