Replacement blades are available for all Silky Saws. The Big Boy range has four tooth sizes. Different applications are performed a little easier with the appropriate tooth size. For example, bamboo cuts neatly with a fine tooth blade as it doesn't fray and split as easily as it does when cut with a large tooth blade.
The teeth are non-set, meaning that they don't have one tooth bent one way and the alternate tooth bent the other way to make a wider cut than the width of the blade.
