Back in the 1970's Howard Kuhn offered a slick tool nicknamed the "Kuhn Cutter". The tool quickly became a mainstay in my workshop, as well as many other rocketeers' workshops of the time. When I finally wore my original cutter out I made an improvised tool with a tab that made it easy to clamp the tool to my workbench, and a slide clamp that made cutting a tube even quicker. Now, a new generation of rocketeers can see the genius of Howard Kuhn! The Kuhn Tube Cutter™ cuts tubes up to 2" in diameter.
