Note 333 — Chapter VI · THE PROTO-SIDERIC OR EARLY IRON AGE OF WEAPONS.

I have elsewhere noticed (chap. iv.) the colours of metals in the painted tombs of Thebes, and the blue (cyanus-colour) of the butcher’s steel. The history of this homely article is instructive. For hundreds of years it retained, in England and elsewhere, its original shape, an elongated cone. At last some ‘cute citizen had the idea of breaking the surface into four edges, and of hardening it with nickel. The simple improvement now fits it for sharpening everything from a needle to a razor: it thus frees us from the ‘needy knife-grinder,’ who right well deserved to be needy, as he disadorned everything he touched.
