Neutral.
In the USA we use the term "Grounded" and in Britain "Earthed" to indicate a connection to ground which is considered neutral. But, in many cases this is either one leg of AC Power, or often the negative terminal of a battery.
A sharp metal piece is typically called a "metal shard" or a "metal splinter."
A 'metal filing ' is a tiny piece of metal that is rubbed off from a large piece by a file.
A metal burr is a small, thin edge of metal that is created when a piece of metal is machined. For example: when a chef's knife is sharpened, a thin piece of metal remains on the edge of the knife.
When a charged rod is brought near an uncharged metal object, it induces a separation of charges within the metal object causing the electrons to move away from the charged rod. This separation of charges creates an attractive force between the charged rod and the metal object, leading to the repulsion of the metal object.

If the piece of sheet metal is a square, then 1600 cm2.
An uncharged electroscope is a device used to detect the presence of electric charge by indicating the absence of its own charge. It typically consists of a metal rod with a pair of lightweight, conductive leaves at the bottom that can move freely. When no charge is present, the leaves hang straight down due to gravity.
When a hot piece of metal is attached to a cold piece of metal, heat will transfer from the hot metal to the cold metal until they reach thermal equilibrium. The hot metal will cool down while the cold metal will heat up until they both settle at a common temperature.
Of itself a metal can not be "shortened". However, a metal OBJECT such as a piece of metal wire can be shortened by cutting a piece off. This would be a physical change.
A small piece of metal is commonly referred to as a "metal fragment" or simply a "metal piece." In manufacturing and engineering contexts, it may be called a "metal shaving" or "metal chip." These terms are often used to describe tiny, often unintended, pieces of metal that have broken off from a larger object.
The closest piece of metal that looks like a Frisbee would probably be a buzz saw.
