Tools for treatment of a substance on a surface

A method for making tools operative for treatment of a substance on a surface of an object or body, with a first tool, which is a treatment tool including:

• a retention portion having a handle with a handle length spanning from a handle root to a handle end, a handle height delimited by a handle back and a handle bottom, and a handle longitudinal axis which extends along the handle length, the handle being made from a rigid polymeric first material, and
• a treatment portion having a blade with a blade length spanning between a blade tip and a blade root, a blade width delimited by a blade back and a blade edge, and a blade longitudinal axis which extends along the blade length, the blade being resiliently flexible and made from a soft and bendable polymeric second material, comprising the steps of:
• providing a backbone having a backbone length and a backbone longitudinal axis extending along the backbone length, the backbone extending outwardly away from the handle root and being made from the first material,
• supporting the blade length in fixed connection to and along the backbone length, and
• configuring the blade for controlled deflection about the backbone,
• whereby when operated to treat a substance, the controlled deflection of the blade limits forces transmitted from the first tool to the surface of and to the object or body.
