Finally, a practical use for jewelry — the Hand Twine Company’s Ring Knife! You wear the ring knife on the finger of your choosing and slip the curved blade under twine, plastic strapping, or other packaging materials you need to cut. It can also be used to cut tape, ribbon, cardboard, small branches, or even light-gauge wire.
The Handy Twine Company fastens the ring knife’s heat-treated steel blade to the aluminum band with nickel-plated brass rivets. They claim they have made their knives in the U.S. since the late 1800’s with the same American materials since World War II.
They sell the ring knife in sizes 3 to 18 and stamp the size on the band for easy reference. Although you can purchase a dozen ring knives for $33 through the Handy Twine Company’s website, if you wear a size 7 ring you’re probably better off buying one at your local Harbor Freight for $1.50.
