Pocket Knife Sharpeners
Pocket knife sharpeners keep a working edge in service when a full sharpening stone setup is not practical. We carry pocket sharpeners from DMT, Benchmade, and Cold Steel built for the field: folding diamond sharpeners, guided pocket hones, and carbide and ceramic tools that ride in a pack or pocket and produce real results on EDC folders, hunting knives, and camp blades. For the technique behind a clean field edge, our knife sharpening guide covers angle control and burr removal.
Portable Pocket Sharpeners for Field and EDC Use
The defining feature of a pocket knife sharpener is self-contained portability: no bench, no oil, no setup. Folding diamond sharpeners lead the category because they cut fast and work dry or with water. The DMT Diamond Sharpener in coarse folds a 4" x 1" diamond whetstone into its own plastic handles, closing to 5" for the pocket and opening to 9 1/2" for a full stroke. The Cold Steel KS-DSDW Dual Diamond Sharpener puts 360 grit on one side for setting an edge and 600 grit on the other for honing, with a honeycomb surface that pulls swarf away from the diamond. For angle control without the size of a bench guided sharpening system, the Benchmade 20 Degree Guided Hone holds a fixed 20 degree angle with ceramic on one side and leather on the other, all in 5.5" made in the USA.
Choosing Between Pocket Sharpener Formats
The right pocket knife sharpener depends on how you use your knives in the field. For restoring a dull blade or fixing minor edge damage on an extended trip, a coarse diamond surface removes steel fastest. For quick touch-ups across a long day, a fine diamond side or the ceramic and leather of a guided hone brings the edge back in a few passes. Carbide tools trade some precision for speed. The Cold Steel KS-21CC 2 in 1 Knife Sharpener pairs a carbide slot for rough sharpening with a ceramic slot for fine edges in an anodized aluminum body with a bead chain for carry. The Kai Pull Through Serration Sharpener handles Kai wide and reversed scallop serrations, and the full range of fixed slot tools lives in our pull through knife sharpeners category. To finish any pocket sharpener work, a small leather strop loaded with sharpening compound refines the edge.
