US Patent 11236983 Measuring tape with variable mass along tape length

A method of producing a measuring tape may include providing a tape measure blade having a first end configured to extend from a housing and a second end configured to be wound on a reel assembly, defining a first non-critical region from the first end to a start of a critical region, defining a second non-critical region from the second end to an end of the critical region, and modifying a mass per unit length of a portion of the blade such that a mass per unit length of the first and second non-critical regions is less than a mass per unit length of the critical region.
