It's hard to believe this handy knife has been around since 1904. It was invented by postman James Caldwell who needed to cut mail bundles while riding in train cars. He also needed to keep his hands free to grab his gun in case the mail train was robbed. Ah, the Wild West.
The ring knife is guaranteed for life.
Blade size 3/4 inch
It had a rounded safety edge but the knife is still sharp so practice knife safety and keep it away from young children.
