Wipe the blade dry. Look for shiny flat spots along the edge (rolled edge) and any chips.

• If you see chips you can catch with a fingernail, plan on coarse grit first.
• If the edge is just dull, start medium or fine.

Match the existing bevel. Do a few light test strokes until the stone hits the bevel evenly. Then keep that angle.

• Choose a simple target: steady angle beats exact degrees.
• Use your shoulders, not your wrists, for smoother passes.

Use coarse only when the edge is damaged or badly rolled. Work one side until you feel a burr, then switch.

• 6 to 10 strokes per side, then check.
• Stop coarse grit as soon as the edge bites again.

Field mindset: do not chase mirror polish. Restore function, then move on.

Move to fine grit to reduce the burr and strengthen the apex. Use lighter pressure than you think.

• Alternate sides every 3 to 5 strokes.
• Finish with 6 to 12 very light alternating strokes.

If you have a strop (or clean leather), pull the edge spine-first. Light pressure only.

• 10 passes per side, then test.
• If the edge gets worse, you are rolling it with too much pressure.

Test with something safe and consistent: thin cordage, a controlled wood feather cut, or paper if available.

• If it cuts cleanly without sliding, stop. Save metal and save time.
• Oil the blade lightly if the environment is wet or salty.

• Blade clean and dry. No sap, grit, or rust.
• Edge check: any shiny flats along the edge.
• Test cut: a short slice on cordage or paper.
• Sharpening tool packed and reachable (not buried).
• Small cloth packed for wiping and drying.

• Stabilize sharpener and stance.
• Angle set with 2 to 3 light test strokes.
• 6 strokes per side on medium/fine.
• Alternate sides every 3 strokes for 2 rounds.
• Strop 10 per side (if available).
• Test, then stop.

• Wet or salty: dry the blade often and oil lightly after.
• Dust or sand: keep grit off the stone and wipe it clean.
• Cold hands: reduce pressure and slow down to avoid slips.
• Low light: rely on consistent stroke count, not visuals.

Use before someone sharpens near camp, kids, or a tight shelter area.

If someone is rushing, assign them a different task. Sharpening injuries are preventable.

Use this when you cannot tell what is happening by sight.

• Round 1: 6 strokes left, 6 strokes right.
• Round 2: 6 strokes left, 6 strokes right.
• Round 3: 3 left, 3 right (2 times).
• Finish: 1 left, 1 right (10 times, very light).

Stop rule: if the edge improves, stop early. If it gets worse, you changed angle or used too much pressure.

If you do not have a strop, you can sometimes use clean leather or clean cardboard.

• Keep it clean. Grit on a strop can scratch and roll the edge.
• Spine-first only. Never push the edge into the material.
• 10 light passes per side, then test.

Heavy pressure makes you wobble and can tear out a weak burr. Use light, controlled strokes and let the abrasive work.

Angle drift rounds the bevel and wastes time. Lock your wrist and move from the shoulder for consistent passes.

Improvised sharpening can work in a true emergency, but it often scratches and rounds edges. Use the tool you packed whenever possible.

In survival situations, time and blood are expensive. If the knife cuts cleanly and safely, stop. Save the steel for later.

• Coarse: chips, dents, or a badly rolled edge.
• Medium/Fine: routine touch-ups and restoring bite.
• Strop: de-burr, refine, and improve control.

• Cuts cordage with a short draw cut.
• Bites wood for controlled feathering.
• Does not slide off the material under light pressure.
