The info wore off the grip and I do not recall what it was. I think it was a German brand. These have been one of my favorite tools for a decade. The jaws are much more narrow than what is typical for side cutters and these handle like a surgeon's scalpel. Best of all, they can be sharpened many many times. Unfortunately, these are getting close to end of life from all of my sharpening and pivot pin wear. I want to get another set, but I have never been able to figure out the brand to find them again. They were given to me by a tech for a computerized Guru bicycle fit machine we had installed in one of our bike shops in 2012.
