Such is the case with Tru-Edge, a brand of knife steel or sharpener. I have one; I think it came from dad, but who knows. It is particularly useful as it has a diamond shaped middle that keeps it from rolling on the counter no matter which side it sits on. The handle is a sturdy wood, and it has a round hook on the end so it can hang in a busy kitchen, if you like. For me, it “hangs” with the Hoffritz (England made) in the drawer.
In looking up information, it appears that Tru-Edge was made by Ontario Knife, a company in business from 1889 to 1986 in Franklinville, New York, or perhaps still in business, as its products show up on all sorts of police websites and survivalist websites as makers of great machetes.
The Tru Edge trademark was registered to Ontario Knife Company on March 3, 1932. Ontario today makes brands that include Agilite Kitchen Cutlery, Old Hickory Kitchen Cutlery, RAT Knives, Ranger Knives, and Sci-Med Scientific Tools.
