An instrument with a shiny surface is said to have what type of finish?

An instrument with a shiny surface is described as having a mirror finish. This type of finish is characterized by its highly polished appearance, which reflects light and gives a smooth, reflective quality. Various surgical instruments, particularly those made of stainless steel, often undergo a mirror finishing process to enhance their aesthetic appeal and to minimize the potential for corrosion and debris accumulation.

In contrast, other finishes such as brushed or matte do not provide that high level of shine and reflectivity. A brushed finish has a series of fine lines or scratches that create a duller surface, while a matte finish absorbs light and lacks shine entirely. Rough finishes, on the other hand, would exhibit an uneven texture and would not reflect light in a shiny manner. Therefore, the term "mirror finish" is specifically reserved for instruments that not only shine but also provide a level of reflection akin to that of a mirror.
