摘要 A brush for use on sensitive surfaces includes a twisted wire core having a handle end and a bristle end, and a plurality of bristles extending radially outward from a portion of the wire core defining a bristle block. The brush further includes a protective tip integrally formed on the wire core at the bristle end for preventing the brush from damaging sensitive surfaces. The wire core and the protective tip are formed from the same material.

主权项 1. A brush for use on sensitive surfaces, said brush comprising: a twisted wire core having at least two leg portions twisted about each other in a helical configuration and having a handle end and a bristle end, all of said leg portions being formed entirely from metal or a metal alloy; a plurality of bristles extending radially outward from a portion of said wire core, said plurality of bristles defining a bristle block; and a smooth, protective tip integrally formed on said wire core at said bristle end for preventing said brush from damaging said sensitive surfaces, said protective tip being formed by melting or welding only said bristle end of said wire core such that said protective tip is made up of existing material from said wire core without the addition of any other quantity of material; wherein all of said leg portions of said wire core and said protective tip are homogeneous.
