Before the advent of mass-produced stainless-steel knives, virtually all blades were made of carbon steel. When a knife, like this three-blade GEC, developed a patina of gray or even black, the change in color simply was an indication of use.
Some of us still consider patina a sign of character — both of the tool and the owner.
The 1095 carbon steel used by Great Eastern Cutlery is known for taking a wonderful patina. It’s the kind of character that suits us just fine.
