How to Sharpen a Hunting Knife
Edge angles for hunting knives, whetstones with oil or water, sharpening vs. honing, strops and the burr, electric sharpeners and grinders, field touch-ups from a game-care kit, and safe handling, following Wikipedia's sharpening article and the Alaska Bowhunter Safety Course.
A sharp knife does field care cleanly and safely; a dull one slips and tears. This guide covers edge angles, the tools, the process and field touch-ups, following Wikipedia’s sharpening article and the Alaska Bowhunter Safety Course. For choosing a knife, see best hunting knives.
Understand the edge angle (Wikipedia)
Sharpening creates a bevel, the angled surface meeting at the cutting edge. Typical angles per side:
- Under 15°: razors, scalpels and specialist slicing knives; very sharp but easily damaged against hard surfaces or bone.
- 15°-20°: most kitchen knives.
- 20°-25°: general-purpose outdoor knives, including pocket and hunting knives, robust enough for light chopping and carving without the edge failing quickly.
- 30° and up: axes, machetes and chisels, for impact work.
Some edges use a “micro-bevel”: a thinner primary grind with the very edge honed at a steeper angle, for durability without losing much slicing performance. Whatever angle your knife has, hold it consistently.
The tools (Wikipedia)
- Whetstones (sharpening stones): blocks of abrasive used by hand, with oil or water as lubricant to reduce friction and flush away metal filings so the stone doesn’t clog.
- Honing steels: rods that realign an edge that has rolled over in use; smooth steels only realign, while ceramic or diamond-coated rods remove a little metal. Honing is maintenance, not the same as sharpening.
- Strops: leather or canvas, often with a polishing compound, used last to remove the burr, the thin wire of waste metal sharpening leaves.
- Electric sharpeners: fast, but with less control over the angle, and they remove metal more aggressively.
- Grinding wheels: for heavy repair; the friction heat can ruin the steel’s temper if it isn’t cooled.
The basic process
- Set your angle and keep it steady across the whole edge.
- Work each side on the stone, keeping it lubricated, until a burr forms along the edge.
- Move to finer abrasives.
- Strop or hone to remove the burr and refine the edge.
Wikipedia notes a well-sharpened edge can cut paper smoothly, but under a microscope even that still shows a tiny rounded apex; a truly sharp edge is too thin to reflect much light.
Field touch-ups
The Alaska course lists a whetstone or other sharpening tool in its game-care kit, along with rope, game bags and water. A few passes in the field keep the edge working through skinning and quartering. Our field care and aging tool and field-to-table venison guide cover what the knife is for, and our whitetail deer profile covers the animal.
Safety
Sharpen with the edge moving away from your hands where you can, keep fingers clear of the edge, and clean and dry the blade afterwards. The Alaska course suggests a first-aid kit able to deal with a serious cut from a broadhead or hunting knife.
