As made-in-USA products generate renewed interest, we’re proud to celebrate 120-years of making every one of our safety ring knives in America! Our Ohio-proud company has been family owned for more than four generations and was founded in 1897 by James R. Caldwell, a US Railway Postal Clerk who had a better idea for cutting twine on mail bundles. Caldwell created his original Handy Ring Knife as a safer, more efficient alternative to the pocketknives used by postal clerks on moving rail cars. Later, the patented cutting tool became know as the Handy Safety Knife – a welcomed solution to helping reduce the risk of injury in the workplace. Our company’s role in Ohio business history and innovation was recognized by the Secretary of State’s Ohio Business Profile Program in 2016. The original safety ring is on rotating display at the Smithsonian Postal Museum.
