The Forgotten Knife Pattern That Changed Pocket Knives
Published: 3 days ago
At first glance, the One Arm Razor pocket knife looks broken or misshapen. But behind that strange squared blade and notched tip lies one of the most ingenious, purpose-built knife patterns in traditional cutlery history.
Born during the Civil War era to help wounded veterans and industrial workers open a slipjoint with just one hand, the One Arm Razor (or One Arm Barlow / One Arm Man's Knife) solved one-handed deployment over a century before modern thumb studs and pocket clips were ever conceived.
In this tabletop bench breakdown, we dive into the history, examine how the notch mechanism actually opens against denim and workbench edges, test the walk and talk, and review the craftsmanship of this forgotten traditional pattern.
