Oftentimes, the longer form of the expression appears: “cut your eyeteeth on..” something. The believe is that eyetooth are the teeth directly below the eyes… where it was once believed that is where wisdom comes from (not to be confused with wisdom teeth!). The expression is most commonly found in the shorter form where the “eye” in eyeteeth is dropped.

Lady Hatton’s use of the phrase occurs in a letter to her husband, dated March 31, 1677, in Correspondence of the Family of Hatton, Chiefly Letters Addressed to Christopher First Viscount Hatton, volume 1 (1878):
