Pließten
Plied (also plied, plied or plied ) is a technical term used in the manufacture of cutlery such as knives and scissors and has its origin in Solingen . It describes the process of particularly fine sharpening of a blade with special means.
process
The shaping of a blade is usually done with coarser grindstones by the "Schlieper". For a homogeneous and scratch-free surface, the "Pließter" finely grinds the blade fixed on a piece of wood, the "Ortspoon", with the "Pleated disk". This is done on a hardwood disc covered with roughened leather. The leather is coated with a mixture of bone glue ( glutin glue ) and abrasive. Plieding can include several stages from "coarse-spliced" to "fine-spliced" to "blue splitted". The grain size of the abrasive is steadily reduced.
Abrasives
A traditional abrasive is emery ( corundum ) from the island of Naxos in Greece . Other abrasives such as silicon carbide and aluminum oxide are also used. The exact recipe of the "Schiewelimm" is often a trade secret.
effect
The very homogeneous surface achieved by the pleating is basically an essential feature of high-quality processing that is recognizable for the user. This distinguishes it from simpler knives, the surface of which usually appears ugly and matt due to visible grinding marks. In addition to the more beautiful appearance, a peened blade also offers far fewer points of attack for acids and other substances that can attack the blade ( corrosion protection ). Special skills are required of the pliester with the "blue pies": The very fine and flawless cut makes reflected light shimmer bluish.
