I don't know but they just had the reputation. I saw a cat 20+ years ago purchase 100s of them and he could not give them away. Sidelocks that would easily catch the eye of a potential purchaser but once examined, they would pass. I was told it was similar steel of that used by Taiwan a decade earlier for tools? And Japan was given a blackeye before that.
