The cutting edge of this Rosle can opener works it's way around cans without touching the contents, and it leaves a cut edge that is blunt and smooth for safety. The cut at the side allows you to lift lids easily and it cuts in such a way that you can reuse lids temporarily. A handsome ring on the end lets you hang and display it on your Rosle Rail System. A better tool, a heavier tool, a more well thought-out tool you'll be hard-pressed to find.
