The S122 sits alongside the S120 in Dexter’s Boston-pattern oyster knives at the same 4-inch length, with a profile that enters at a shallower angle. Which one suits comes down to how a shucker holds the shell and where they attack the hinge.
It goes to the same work — large deep-cupped oysters at a raw bar or a shore kitchen — but the flatter entry helps if you brace the oyster on a bench rather than in the palm. Anyone shucking in volume develops a preference and sticks with it.
Dexter-Russell has been making cutlery in Southbridge, Massachusetts since 1818 and is the oldest cutlery manufacturer still operating in the United States.
