Hello, Bob. Thanks for the starting off point. I was able to track down a patent issued to Stuart A Parsons, Assignee Stanley Tool Works, July 17 1928 , Patent Number 1677684. From what I have read, this cuts steel banding and at the same time leaves a rounded end for safe handling of the banding (strap) Early OSHA?????? I have some steel banding at work and other various strap cutters here, I will cut a few samples, (tomorrow) and try not to end up on Worker's Comp. Regards, Lou
