How to Sharpen a Knife the Right Way: A Complete Guide

A sharp knife is a safe knife. Whether you're working with a prized EDC folder, a kitchen blade, or a fixed blade field tool, keeping your edge sharp makes every cut cleaner, safer, and more efficient. The good news? Sharpening a knife is a skill anyone can learn — and once you do, you'll never go back to struggling with a dull blade.

Understanding the Edge: Bevel and Angle

Before you sharpen, it's important to understand your blade's edge geometry. Most knives are sharpened at an angle between 15° and 25° per side. Japanese-style blades tend to use a finer 15°–17° angle for a more precise edge, while Western and outdoor knives typically use 20°–25° for added durability. Maintaining a consistent angle is the single most important factor in getting a sharp, even edge. Curious about what steel your blade is made from?

Sharpening Tools: Which One Is Right for You?

  • Whetstones (sharpening stones) – The gold standard for serious sharpeners. They offer the most control and produce the finest edge. Start with a coarse grit (200–400) to reshape the edge, then move to a fine grit (1000–3000) to refine it, and finish with a polishing stone (6000+) for a razor edge.
  • Diamond stones – Faster cutting than traditional whetstones, great for harder steels and quick touch-ups.
  • Pull-through sharpeners – Easy and fast, but remove more metal and produce a less refined edge. Best for kitchen knives, not premium blades.
  • Electric sharpeners – Convenient but aggressive. Use sparingly and only on knives that don't require a precise edge angle.
  • Leather strop – Not a sharpener, but an essential finishing tool. Stropping realigns the edge and polishes the bevel for a razor-sharp finish.

Step-by-Step: How to Sharpen on a Whetstone

  1. Soak your whetstone in water for 5–10 minutes (if water-based).
  2. Place the stone on a non-slip surface.
  3. Hold the blade at your desired angle (15°–20° for most knives).
  4. Using light, consistent pressure, push the blade across the stone edge-first, as if slicing a thin layer off the surface.
  5. Alternate sides every few strokes to sharpen evenly.
  6. Progress from coarse to fine grit until you feel a slight burr on the opposite side — then switch and remove it.
  7. Finish with a leather strop to polish and align the edge.

How Often Should You Sharpen?

A knife used daily should be honed with a strop or honing rod weekly and sharpened on a stone every few months, depending on use. A blade that tears rather than slices is overdue for sharpening. Don't wait until it's completely dull — light maintenance keeps your edge in peak condition longer. This applies equally to folding pocket tools and fixed blade knives.

Pro Tips for a Better Edge

  • Always sharpen in a well-lit area so you can see the reflection of the edge.
  • Use a marker on the bevel to check if you're hitting the right angle — the marker will wear off where the stone makes contact.
  • Let the stone do the work — excessive pressure causes uneven wear and a rough edge.
  • Store knives properly (on a magnetic strip or in a sheath) to protect the edge between uses.
  • For Damascus blades like the Red Deer® 8.5" Damascus Hunting Knife, apply a light coat of oil after sharpening to prevent oxidation of the layered steel.
