Types of Knife Sharpeners

While many are familiar with the traditional whetstone, there’s a spectrum of knife sharpeners in the market. The ceramic sharpening rod, a tool revered for precision, offers a unique approach to blade honing. However, exploring the types of knife sharpeners reveals a realm of variety, from handheld to electric, each with unique benefits.

Understanding these types can help you choose the best one for your needs.

Sharpening Stones or Whetstones: These are one of the oldest forms of knife sharpeners. They are rectangular blocks made from different abrasive materials, like ceramic, diamond, or natural stone.

The user manually moves the knife across the stone at a precise angle to sharpen the blade. They come in varying grits, from coarse to fine, allowing for versatile knife sharpening.

Honing Rods or Sharpening Steels: These are long, rod-shaped tools often used by chefs to maintain the edge of a knife between sharpening.

They don’t remove material from the blade but instead realign the edge. They come in different materials like ceramic, steel, and diamond.

Handheld Manual Sharpeners: These are small, portable devices that have built-in sharpening slots with abrasive materials, often ceramics or diamonds.

The user pulls the knife through these slots to sharpen the edge. Many also have preset angles for more consistent results.

Electric Knife Sharpeners: These are countertop devices that use electricity to spin the sharpening stones.

They typically have several stages of sharpening from coarse to fine and are straightforward to use — simply draw the knife through the slots.

Pull-through or Slot Sharpeners: Similar to handheld sharpeners, these have one or more slots that you pull the knife through. However, these are often larger and have a sturdy base to rest on a countertop.

Sharpening Systems: These are comprehensive kits that often include clamps to hold the knife and a guide to maintain the correct sharpening angle.

They might use stones or rods and provide high precision sharpening.

What To Look For In A Knife Sharpener

When wondering what to look for in a knife sharpener, consider the diamond sharpener’s premium hardness and precision. It’s a quintessential tool ensuring your knife’s longevity and optimal performance.


Here are other features to look for:

Material

Tungsten carbide stands as a robust and effective material for ensuring knife sharpness, contributing to a long-lasting and precise edge. Some common materials include diamond, ceramic, and carbide.

Diamond is the hardest, making it a popular choice for sharpening knives quickly.

On the other hand, ceramic provides a smoother and finer edge.

Carbide is excellent for quickly restoring a dull blade.

Each material has its pros and cons, so determine which one suits your needs best.

Size and Portability

Size and portability play a crucial role for outdoor enthusiasts and survivalists. A pocket sharpener is a compact and convenient option, making it an ideal companion for on-the-go blade maintenance.


You want a knife sharpener that is compact and lightweight, something that can easily fit in your backpack or pocket without weighing you down.

However, the size should not compromise its efficacy or ease of use.

Ease of Use

Survival scenarios often demand quick action, so a sharpener that is easy to use is crucial. Look for a model with an intuitive design that allows you to sharpen your knife without any hassle. The last thing you want to deal with during an emergency is a complicated sharpening process.

Sharpening Angles

Sharpening angles significantly impact the blade’s performance and cutting ability. An adjustable sharpener offers flexibility in choosing the appropriate angle for various knives, enhancing blade efficacy and longevity.

Most sharpeners have a preset angle, while some models allow you to adjust the angle. It’s essential to choose the right angle to maintain the sharpness and functionality of your knife.

Multi-Functionality

Multi-functionality is a desirable feature, providing diverse sharpening options and additional tools. The Leatherman multi-tool, with built-in sharpening capabilities, epitomizes versatility and comprehensive functionality.

Some models come with additional features like fire starters or emergency whistles built into the design. These extra functions can prove invaluable in certain survival situations.

Price Point

While price point is crucial, discerning the value offered by a sharpener is equally important. Brands like Morakniv balance cost and quality seamlessly. Look for a combination of cost-effectiveness and high performance.

With some research, you can find some of the best survival knife sharpeners at an affordable price. It’s about finding the right balance between cost and functionality.
