There is not much left to review after watching the video above and reading the details from Best Made Co.’s website. It’s American innovation in a small ring-size package. It’s been around since 1904 and the shear simplicity has kept it relevant in our 2012 world. Manufactured in Upper Sandusky, Ohio for over a century.

From Best Made Co.’s website:

• Patented in 1912
• Aluminum ring, steel blade
• Titanium Nitride coating on the blade for extended sharpness
• comes in a three pack (sizing below)

“James Caldwell ran a railway mail route from Pittsburgh to Chicago. On the bucking train he watched over his cargo with a sidearm and ofttimes worked a knife to open twine wrapped bundles of mail. This job was a juggling act and so Caldwell invented the Handy Twine Knife: a highly useful cutting tool worn around the finger (any finger) thus freeing up the hands to shoot bandits. Since it’s invention in 1904 his knife would become standard issue for US postal workers and today the Handy Twine Knife is good at cutting fishing line, thread, flowers, plants, light gauge wire, citrus fruits and all those boxes that arrive from Best Made. The Handy Twine Knife Company still flourishes under the fourth generation ownership of the Caldwell family.”
