The
Famous Case XX Trademark
Many people
have come to recognize the famous "Case XX" stamp as the
signature of the finest knives in the world. The history of
the trademark goes back to the early days of W.R. Case &
Sons Cutlery Co.
In those
days, the "XX" was used as a quality check system during the
heat treating of the blades. When blades were put through
the initial hardening furnace, an "X" was marked on the pan
holding the blades. When the blades were returned to the
oven for tempering, a second "X" was added. "XX" then,
showed that each blade had been properly and fully-treated.
