D.R.BARTON Cooper's Chamfer Knife Please read full description, and see all photos. I strive for large clear photos that show all the details...good or bad. Ask for specific photos or additional details if needed. Being a tool collector for almost 50 years, this has been lightly cleaned by hand to preserve it's history and prevent rust. No disc grinders or belt sanding. Approximately 5" blade. Super clean tool with the original handle. I doubt you will find a nicer one. I think this would be called "left handed" but hopefully someone with more expertise with cooper's tools will chime in.
