In woodworking and metalworking, the scratchbrush is employed for surface preparation, rust removal, or oxidization enhancement. It is commonly used to create fine scratches or patterns on wood, metal, or other materials, which can enhance the adherence of paints, varnishes, or coatings. Additionally, it can be utilized to clean and polish intricate or hard-to-reach areas.

The word "scratchbrush" appears to be a compound noun consisting of two individual words: "scratch" and "brush".
The term "scratch" originated from the Old Norse word "skrā, skræ" meaning "mark, trace, or scratch". This Old Norse root later developed into the Middle English word "scracche", which was used to describe a mark made by scratching. Over time, it expanded to refer to the action of making such a mark or using an instrument to scratch a surface.
On the other hand, the noun "brush" can be traced back to the Old English word "brysce" or "byrst" meaning "twig". It was influenced by the Old French word "broisse" which meant "tuft of bristles" or "bundle of twigs".
