erdix, also known as Talus or Calus. A Greek mythological figure, the nephew of Daedalus a skilled craftsman. Perdix apprenticed to Daedalus and under his tutelage was credited with the invention of the first saw fashioned from the backbone of a fish. He also attached two branches of metal together with a rivet on one end and sharp points on the business end to craft the first pair of dividers.
Daedalus burned with jealousy at his inventive nephew and pushed him off a towering cliff. Athena came to the young inventors rescue and turned him into a partridge before his body was dashed against the rocks below.
Which is why we will never know the secret behind the saw nib.
