Buck Knife Sharpeners
Maintain Your Buck's Factory Edge
Buck grinds their knives at 13-16 degrees per side - a relatively acute angle that delivers excellent cutting performance. Their EdgeTek sharpeners are designed to match this factory geometry while working specifically with Buck's 420HC steel, which sharpens easily despite its 57-59 HRC hardness.
Diamond-Coated Sharpening Technology
All Buck EdgeTek sharpeners use 100% diamond-coated surfaces that cut through 420HC steel efficiently without clogging. Unlike traditional whetstones that can gum up with soft stainless steel, diamond surfaces maintain consistent cutting action throughout the sharpening process.
The EdgeTek Ultra Steel features three grits on one tool - 325 coarse for edge repair, 750 medium for standard sharpening, and 1200 fine for finishing. The oval shape allows controlled strokes while the 10-inch length handles everything from small folders to large hunting knives. At 15.75 inches overall, it provides leverage for consistent angle maintenance.
Bench Stones for Shop Work
The EdgeTek Bench Stones offer stable platforms for maintaining knives at home. Available in 325 coarse grit for reprofiling damaged edges or 750 medium grit for routine maintenance, these lightweight stones feature finger grips for single-handed operation. The clear plastic lid protects the diamond surface during storage and transport.
For hunters and outdoorsmen who sharpen multiple knives, bench stones provide the control needed to maintain consistent angles across different blade lengths. The flat surface works equally well on straight edges and recurves.
Field Knife Sharpening Solutions
The EdgeTek Dual Flat Pocket Stone combines 325 coarse and 750 medium grits in a slim profile that fits in pack pockets. This field sharpener handles everything from touching up an edge between deer to removing small chips from hitting bone. The plastic sheath prevents the diamond surface from damaging other gear.
The EdgeTek Field FlipStik takes portability further with its folding design. Closed at 5 inches, it opens to 9.125 inches for full-length sharpening strokes. The 750 medium grit on both sides of the oval rod makes it the best field knife sharpener for maintaining a working edge without removing excessive metal.
Sharpening Buck's 420HC Steel
Buck's heat-treated 420HC responds well to diamond sharpeners because the steel is hard enough to avoid gumming yet soft enough to sharpen quickly. A few passes on medium grit restore cutting ability, while the fine grit or a leather strop brings back hair-shaving sharpness.
For field knife sharpening, maintain the factory 13-16 degree angle rather than trying to reprofile to steeper angles. Buck's geometry balances cutting performance with edge stability - changing it often leads to faster dulling or edge rolling.
Most Buck knives only need the medium 750 grit for regular maintenance. Use coarse grits only for damage repair or reprofiling work. The fine 1200 grit or stropping creates the polished edge preferred for skinning and detail work.
