Abstract: A method and tools operative for treatment of a substance in association with a surface of an object or body have a first treatment tool and a second backing tool. The treatment tool has a rigid retention portion and a treatment portion, and is manufactured as a single integrated tool. A backbone extends in cantilever out of the retention portion to support a resilient and flexible blade, retained at a twist angle relative to the handle. The blade is configured for controlled deflection about the backbone when vertical forces in excess of a predetermined force are met, to prevent damage to the surface or to the object. The retention portion and the treatment portion are disposed in mutual angular spatial relationship for ease of use of the tool. The backing tool supports the object during treatment.
