The worst knives I’ve ever owned and used we’re back in the late 1970s. One was a cheap switchblade a friend had smuggled in from Mexico (we were 14 at the time) that he sold me for $5 (he got the better deal). The blade was stamped “Rizzuto estileto Milano” and “stainless”. Total POS, but I carried it in my pocket to school for awhile, thinking it was cool. Until one day I felt a slight scratching/poking sensation on the right side of my junk and discovered the switchblade had come partially open in my pocket, and the tip was lightly touching my right you-know-what. I never carried it again.
The other crappy knives I had were a few ultra-cheap pocketknives that came in packages from Sears at the time. They were made by Colonial and obviously made to be boys’ first knives. One was a little Barlow pattern, one was a scout-type pattern, and one was a little 2-blade jack knife. They had the cheapest molded plastic scales that were loosely fitted, and for coloring looked like someone just swabbed each scale once with purple paint. The blades were some type of chrome-finished carbon steel, and all blades had play in all directions, although they did snap closed OK. They were intended to be misused and lost, as boys often do with things. I never lost them, but simply used them for stuff without worrying about them, then put them away and only carried my good pocketknives.
