The James Barry Sharpening Diamond Pen File (600 grit, Model EFOF) is a compact, do-everything sharpener engineered for precision in the field or workshop. Its steel core is electroplated with monocrystalline diamond abrasive for fast cutting and long life. Three surfaces cover nearly every task: a V-groove to quickly tune fishing hooks and dart points, a flat face for straight blades and edges, and a curved face that reaches serrations and contours or shapes model components with control.

The clever pen-style format keeps the file protected when not in use—unscrew it from the handle, flip it, and screw it back to deploy in seconds. Pair with James Barry Sharpening original-formula lapping fluid to keep swarf at bay, improve cut, and secure your 5-year guarantee. Whether you’re bankside, at the oche, in the field, or at the bench, this is the sharpener you’ll actually carry.
