An arbelos  or, an arbelos as Archimedes called it  means a "shoemaker's knife" in Greek.
This was appropriate, as it resembled the knives used by ancient cobblers and leather workers. (Weisstein, 2005)
Archimedes was believed to be the first mathematician to study the mathematical properties of this intriguing shape.
However, the arbelos also attracted the attention of many famous mathematicians such as Descartes, Fermat, and Newton. (What Is, 2005)
It is also noted that the location of the central notch is arbitrary. (Archimedes Book, 2005)
