Your Georgia oyster knife was made exactly like it would have been made in the 19th century.

This is not an eating utensil, it is a tool.It has been acid etched to inhibit oxidation,and has been coated with a non corrosive paint.It will rust so don't put it in your mouth.

The treatment of the tool should last about 3 years,then you can brush it off with a wire brush (that you might clean your grill with)and repaint.

For the very best results eat lots of oysters often, and wipe the knife down with mineral oil when you are finished.
