Buyers Guide for Buying the Best Pocket Knife Sharpener

When it comes to sharpening pocket knives and other outdoor specific tools there are certain criteria that must be met. A big one is portability and packability. Another is user friendliness and the size of the total sharpening system.

Below we’ve covered some of the most commonly asked questions about knife sharpeners and broken down the different types and materials used.

Total Tool Size and Weight

One of the most important factors for a hiking or survival knife sharpener is size and weight. A good sharpener is an essential item but it can’t take up a lot of space. A full sharpening system or a large shop style sharpener doesn’t suffer from these same restrictions.

Look for ones marketed as pocket or micro sharpeners. These are exceptionally small and have the basics needed to maintain an edge in the field. They can be used for major repairs but generally don’t do quite as a good a job as more purpose built sharpeners.

Grit Size

With knife sharpeners the grit number gets larger the finer the grain is. A very rough grit sharpener, suitable for initial reshaping and coarse grinding, will be around a 100-500. These are best used to repair damaged or chipped knives.

Once you’ve got a basic blade on you can move up to higher grit like 1000, 2000, or 3000 for putting a rough edge on. 4000 to 8000 grit stones are finishing and polishing stones that help give your knife edge that last razor sharp step and put a mirror finish on the blade.

Is the Sharpener Multi-Functional

Most sharpeners that are more than a simple whetstone definitely qualify as multi tools. Even standard whetstones are multi functional. They can be used to sharpen knives, scissors, yard tools, axes, and other bladed implements.

Hiking, camping, and survival focused sharpeners often have multiple types and varieties of sharpeners built right in. This combination of multiple tools and multi functional utility place knife sharpeners firmly in the multi tool category.

Sharpener Materials

When it comes to modern knife sharpeners there are three main types of materials under dozens of brand names and monikers. These are diamond, tungsten carbide, and ceramic. There are also traditional whetstones, covered more in detail below.

Diamond Sharpener – Diamond sharpeners are the most recent advance in sharpener technology. They use tiny lab grown diamond chips that are attached to plates, rods, and other sharpening forms. Diamond is the hardest material known to man. This makes it perfect for use as a sharpening and honing material.

The small chips work to grind off small bits of metal to create an evenly sharpened blade. Many serrated knife sharpeners rely on diamond grit materials because they can be irregularly shaped.

Tungsten Carbide Sharpener – Carbide sharpeners are used for aggressive repair of damaged blades. They quickly scrape away the surface layer of metal on a knife blade and leave a rough edge below. Most systems that use a carbide sharpener will also include either a diamond or ceramic sharpener.

An important point to keep in mind when using a carbide sharpener is that they’re somewhat rough on the blade. They tend to pull of a bit more material than a similar grit whetstone.

Ceramic Sharpener – Ceramic sharpeners are used to smooth and polish an already mostly sharpened knife blade. When paired with a carbide sharpener they create an effective pair of rough and fine sharpening capability.


Whetstones have been used to sharpen metal tools since there have been metal tools. They’re the most basic type of knife sharpener available. They consist of a small piece of hard, consistently grained mineral that abrades metal off a knife blade.

To use a whetstone you put water or oil on the surface of the stone for lubricant and draw your blade across it. It takes some skill to get right as you have to maintain the proper blade angle throughout your pass. Because of this whetstones are the least beginner friendly sharpening method.

In the past whetstones were naturally mined but for the last 50 or so years they’ve almost entirely switched to synthetic stones. Natural stones have history behind them but the synthetic stones have consistency and cost savings. It’s possible to create stones that have exactly the same grit and grain pattern in a scientific manner.

The most recent advance in whetstone technology are diamond plates. These use the same principle as a whetstone but rely on diamond grit plates to do the actual sharpening. They require the same skill to use as a traditional whetstone but allow you to more rapidly perform the sharpening.

Slot Sharpeners

If you’re just starting out with knife sharpening a slot sharpener is one of the most user friendly options available. It’s basically two small pieces of carbide, ceramic, or diamond grit sharpener suspended at a specific angle.

To use them all you have to do is apply firm downward pressure on the blade and draw it along the sharpener slot. As it passes through each level in turn it removes different amounts of material and leaves you with a sharp knife blade.

Electric Sharpeners

Electric sharpeners combine the features of slot sharpeners with multiple materials and grit levels. They automatically grind off an specified amount of material with a single pass. You can get a very precise blade angle and sharpness, but at a cost.

Electric sharpeners are known to be fairly aggressive with their sharpening. They remove more blade material than is absolutely necessary and can lower the lifespan of your knife. Also, they usually require wall power to operate and are quite large and heavy.

Not a great option to put in your gear bag or hiking pack but an acceptable choice for your workshop or kitchen.
