Sharpen Your Folder: The Best Knife Sharpener Buying Guide

A sharp folding knife makes all the difference. It cuts through tasks with ease and feels great in your hand. But even the best folding knife dulls over time. That’s where a good knife sharpener comes in. This guide helps you find the perfect sharpener for your folding knives.

1. Key Features to Look For

When you shop for a knife sharpener, keep these important features in mind.

  • Ease of Use: You want a sharpener that’s simple to operate. Some sharpeners have guides that hold your knife at the right angle. Others require a steady hand.
  • Portability: Folding knives are often carried around. A sharpener that’s small and light is easy to take with you.
  • Versatility: Does the sharpener work on different types of steel? Can it sharpen serrated edges?
  • Angle Control: Most folding knives work best with a specific sharpening angle. Look for sharpeners that help you maintain this angle.
  • Grit Options: Sharpeners have different grits, which are like sandpaper grades. Coarse grits fix chips. Medium grits sharpen. Fine grits polish the edge.

2. Important Materials

The materials used in a sharpener affect how well it works and how long it lasts.

  • Diamond: Diamond sharpeners are very hard. They sharpen quickly and work on tough steels. Diamond plates and rods are common.
  • Ceramic: Ceramic sharpeners create a very fine edge. They are good for honing and polishing. Ceramic rods are often used for touch-ups.
  • Carbide: Carbide sharpeners are aggressive. They remove metal fast. Use them carefully, as they can wear down your knife edge quickly.
  • Whetstones (Water Stones/Oil Stones): These are flat stones that use water or oil. They offer great control and can create incredibly sharp edges. They often require more practice.

3. Factors That Improve or Reduce Quality

Several things can make a sharpener better or worse.

  • Build Quality: A well-built sharpener feels sturdy. Its parts fit together well. Cheap plastic can break easily.
  • Abrasive Material Quality: High-quality diamond or ceramic abrasives sharpen more effectively and last longer.
  • Angle Guides: Precise angle guides help you get a consistent edge. Poorly designed guides can ruin your knife’s angle.
  • Sharpening System Design: Some systems are better at restoring a dull edge than others. Others excel at maintaining a sharp edge.

4. User Experience and Use Cases

How you plan to use the sharpener matters.

  • Quick Touch-Ups: If you just need to quickly sharpen your knife before a task, a simple pull-through sharpener or a ceramic rod works well.
  • Restoring a Dull Blade: For a knife that’s lost its edge, you’ll need a more robust system like a whetstone or a multi-stage sharpener with coarse grits.
  • Travel: For camping, hiking, or everyday carry, a compact, lightweight sharpener is ideal. Some sharpeners are designed to fit in your pocket.
  • Home Use: At home, you have more options. You might prefer a more precise system like a whetstone or a benchtop sharpener for the best results.

A good sharpener is an investment. It keeps your folding knife ready for action. Choose one that fits your needs and skill level.


Frequently Asked Questions (FAQ)

Q: How often should I sharpen my folding knife?

A: You should sharpen your knife when it struggles to cut paper or soft materials. This could be after a few uses or after many uses, depending on how you use it.

Q: Can I sharpen serrated edges with any sharpener?

A: No. Most sharpeners only work on straight edges. You need a special sharpener designed for serrated blades, often a ceramic rod or a specialized sharpening system.

Q: What is the best sharpening angle for a folding knife?

A: The ideal angle is usually between 15 and 20 degrees per side. Many sharpeners have built-in guides for these angles.

Q: Will sharpening damage my knife?

A: Using the wrong sharpener or sharpening too aggressively can damage your knife. Always follow the instructions and use a sharpener suited for your knife’s steel.

Q: What’s the difference between honing and sharpening?

A: Sharpening removes metal to create a new edge. Honing realigns the existing edge to make it sharper. Honing is done more often than sharpening.

Q: Are electric knife sharpeners good for folding knives?

A: Some electric sharpeners are too aggressive for folding knives. Look for models specifically designed for smaller blades or use them with extreme caution.

Q: Do I need different sharpeners for different types of steel?

A: Very hard steels might need diamond or carbide sharpeners. Softer steels can be sharpened with ceramic or whetstones. Most good sharpeners handle common knife steels well.

Q: How do I maintain my knife sharpener?

A: Follow the manufacturer’s instructions. For whetstones, you might need to flatten them. Keep abrasive surfaces clean to ensure they work best.

Q: Can I use a sharpening steel on my folding knife?

A: A sharpening steel is a honing tool, not a sharpener. It re-aligns the edge. It won’t restore a truly dull blade but helps maintain sharpness.

Q: What is the easiest type of sharpener for a beginner?

A: Pull-through sharpeners with fixed angle guides are often the easiest for beginners. They require minimal skill to get a decent edge.
