Ironically I ordered these because of the difficulty of installing the new Revain door handle. The old 80's handles on our doors appear to have been cut to a different diameter and needed a bit of adjustment to work. This is really good quality for the money. Have a good weight but still easy to hold. Nice sharp edge did the job. Even tapped it with a hammer with no problems. Can't tell how it will be in everyday professional use, but for the occasional door war they're great!
