The Ultimate Buying Guide for Knife Sharpeners for Folding Knives
A sharp folding knife is a safe and useful tool. A dull knife can slip and cause accidents. Buying the right sharpener makes keeping your EDC (Everyday Carry) knife ready simple. This guide helps you pick the best sharpener for your folding knives.
Key Features to Look For
When you shop, look for sharpeners that match your knife’s needs. Not all sharpeners work well on every blade. Consider these features:
- Angle Control: Most folding knives have a specific angle ground into the blade (usually between 15 and 25 degrees). Sharpeners with fixed guides or adjustable stops help you maintain this exact angle. This is very important for a consistent edge.
- Portability: Since you use folding knives on the go, your sharpener should be small. Pocket-sized sharpeners or pull-through tools are easy to carry in a kit or pocket.
- Grit Variety: Good sharpeners offer different levels of coarseness, called grit. You need coarse grit (lower numbers) for fixing chips or very dull blades. You need fine grit (higher numbers) for honing and polishing the edge after sharpening.
- Ease of Use: Beginners should look for simple systems, like V-shaped pull-through sharpeners. Experienced users might prefer whetstones that offer more control.
Important Materials in Sharpeners
The material of the sharpening surface determines how fast and effectively it removes metal from your blade.
Ceramic
Ceramic rods or plates are very common. They work well for general touch-ups and light honing. They are durable and often found in compact, pull-through designs.
Diamond
Diamond sharpeners cut very fast. They are excellent for repairing very damaged or extremely hard steel blades. Diamond surfaces last a long time without wearing down.
Tungsten Carbide
This material is often used in V-shaped slots. It is very hard and sharpens quickly. However, it removes metal aggressively, so use it carefully on expensive or thin blades.
Factors That Improve or Reduce Quality
The quality of the sharpener directly affects the quality of your knife edge. Pay attention to these factors:
Improving Quality:
- Stable Base: A sharpener that sits firmly on a table prevents wobbling. Stability ensures you keep the correct angle during the sharpening stroke.
- Lubrication Needs: Oil stones or water stones require a lubricant (water or honing oil). Proper lubrication keeps the stone clean and helps it cut smoothly.
- Fine Finishing Stages: Sharpeners that include a leather strop or a very fine ceramic stage create a razor-sharp, polished edge.
Reducing Quality:
- Fixed, Wide Angles: If a pull-through sharpener has slots set too wide, it might not match your knife’s precise factory angle. This can create a rounded or weak edge.
- Cheap Plastic Bodies: Plastic bodies flex under pressure. This flexing changes the angle, leading to an unevenly sharpened blade.
- Only Coarse Grit: A sharpener that only has one coarse setting cannot refine the edge. The blade will feel sharp but dull quickly.
User Experience and Use Cases
How you plan to use your sharpener guides your purchase.
For Quick Field Use (Camping/Hiking):
You need something small and tough. A diamond rod or a small, fixed-angle pull-through sharpener works best. These tools are designed for fast, rough edge restoration when you are away from home.
For Home Maintenance (EDC Knives):
If you sharpen at home, a guided system or a small whetstone set offers the best results. These systems take more time but give you maximum control over the final edge geometry.
Remember: Always sharpen away from your body. Clean your blade thoroughly after sharpening to remove metal dust.
10 Frequently Asked Questions (FAQ) About Folding Knife Sharpeners
Q: Do I need a different sharpener for every folding knife?
A: Not necessarily. Many good systems can handle most common pocket knife angles. However, specialized knives (like recurves or serrated edges) might need special tools.
Q: What is the best grit size to start with?
A: If your knife is only slightly dull, start with a medium grit (around 600-800). If the edge is completely flat, you should use a coarse grit (around 200-400) first.
Q: Are pull-through sharpeners bad for my knives?
A: Quality pull-through sharpeners are fine for general use. Lower-quality ones use very hard carbide cutters that remove metal too quickly, which shortens your blade’s life over many years.
Q: Should I use water or oil with my whetstone?
A: Check the stone instructions. Water stones require soaking or splashing with water. Oil stones require a light honing oil. Never mix the two types of lubricants.
Q: How often should I sharpen my folding knife?
A: This depends on use. If you use your knife daily for tough cutting, sharpen it every few weeks. If you only use it occasionally, sharpen it every few months.
Q: What does “honing” mean compared to sharpening?
A: Sharpening removes metal to create a new edge bevel. Honing (or stropping) realigns the microscopic edge that has bent over from use. Honing makes the blade feel sharp again without removing much material.
Q: Can I use a sharpening stone designed for kitchen knives on my pocket knife?
A: Yes, if the stone has the right grit range. Kitchen knives often use a slightly wider angle (around 20 degrees), so be careful to match your folding knife’s angle for the best result.
Q: How do I know when my folding knife is sharp enough?
A: The paper test works well. A truly sharp knife should cleanly slice through a hanging piece of paper without tearing or catching.
Q: What is a strop, and do I need one?
A: A strop is a piece of leather or canvas, often loaded with a fine abrasive paste. You use it after sharpening to polish the edge, making it extremely keen. It is highly recommended for the best edge.
Q: Are expensive sharpening systems worth the extra money?
A: For dedicated users, yes. Expensive systems usually offer better angle stability and higher-quality abrasives (like high-grade diamonds or ceramics), which provide a superior, longer-lasting edge.
