A method of automatically cutting a variable tooth pitch band saw blade from a bulk reel 40 of blade material 14 is achieved by using a cut to length machine 8. Blade material 14 from the bulk reel 40 is pulled on to a bed 42 of the machine 8. The blade material 14 is placed between rollers 50, which are powered and one of which is a metered roller 44 actuable to dispense a desired amount of the blade material. The cut to length machine 8 includes a cutting section 18 and an optical sensor 24, both connected to and controlled by a computer 46. The cutting section 18 comprises suitable cutting means, such as a mechanical cutter or laser cutter.
