...there is yet ample evidence of the existence of clasp-knives ages before the production of the Canterbury Tales. Among Etruscan antiquities in the Bronze Room of the British Museum are several clasp-knives, some of them with bone, others with bronze hafts, their blades being of iron — a metal employed for cutting implements by the Tyrrhenian tribes, at a far remote era.

A scalprum or penknife has been found in Rome, the blade shutting into a bone haft, which is carved to represent the upper half of a human body; and clasp-knives, with iconic handles of the Roman era, have been discovered both in France and this country.
