What Tools Are Needed To Sharpen A Knife?
Knife sharpening is not just knife sharpening but rather knife maintenance. Different knife sharpening tasks do different things to the blade’s edge and different tools to get these tasks done.
There are three main aspects to knife sharpening.
- Edge repair. This sharpening task is to repair a damaged edge on a knife and restore it to the point where it can be properly sharpened.
- Knife sharpening. This process is sharpening the edge of a knife that has become dull.
- Honing a knife. Honing is taking the sharpness of an already sharp knife up a notch to restore keenness to the sharp edge.
Each of these sharpening tasks requires different tools or different components on the same tool to achieve the desired result.
Your location may also determine the type of tools you use for each task since sharpening a knife in the field is different from sharpening a knife at home.
Let’s get into the tools that we recommend as the must-have tools to sharpen your knives for each type of sharpening task in different circumstances.
1. Whetstones For Sharpening Knives
If you are serious about your knife maintenance and achieving spectacular results on the edges of your knives, then whetstones would be one of the primary tools to consider in your knife sharpening toolbox!
Whetstones are considered in most knife sharpening circles as the best method to get a superb edge on your knives since the process is one by hand. This allows angles to be modified according to the function and blade type of the knife you are sharpening.
One great advantage of sharpening with whetstones is that they can be used for the full spectrum of knife sharpening tasks, from edge repair to sharpening and honing. Whetstones in 3 or 4 different grits will give you what you need to maintain the edges on almost any knife in your possession.
There are some disadvantages to whetstones, including the following.
- Whetstones require practice. Sharpening knives on a whetstone is a learned skill that takes time to master.
- Whetstones can be expensive. Cheap whetstones are not worth spending any money on, so you will need to spend a bit more money to acquire quality stones.
- Not portable. Whetstones are generally considered a workshop-type tool, which you would use either at home or in your garage to sharpen your knives. It is generally not considered a field sharpening tool.

2. Pocket Sharpeners For Knife Sharpening
Pocket sharpeners can be an important tool to have available for touching up your blade out in the field. Several types of pocket-sized knife sharpeners fit the bill in this regard.
Some of these sharpeners have the advantage that they can perform sharpening and honing functions, but it is unlikely you will be able to use a pocket sharpener to fix a damaged edge.
We have selected two types of pocket sharpeners that we recommend as good field knife sharpeners to put an edge back on your knife when you cannot get to your whetstones.
The advantages of pocket sharpeners are their portability, making sharpening and honing your knife anywhere anytime, and easy task.
The disadvantage of pocket sharpeners is they lack the capacity to fix a damaged knife edge, and the degree to which the knife can be sharpened is limited.
DMT Diamond Plate Folding Sharpener
Diamond plates are used with the same action as whetstones, making them easy to use if you have already learned the skill on your whetstones.
The DMT Diamond Plate Folding Sharpener (Amazon link) has a fine and extra-fine grit in the folding tool. It gives you the ability to sharpen or finetune the edge on a knife. The tool is foldable and small enough to be portable in most situations.
The advantage of diamond plates is that you do not need water or other lubricants to use them. They can be used dry if you have no other option, but they work better when a little water is splashed on them during the sharpening process.
Lansky PS-MED01 BladeMedic
The Lansky BladeMedic is a great pocket sharpener that is small enough to slip unnoticed into any pocket and have the capability on hand to put an edge on your knife wherever you need it.
The Lansky BladeMedic (Amazon link) includes a Tungsten Carbide sharpening slot and a ceramic honing slot. A nice feature of this pocket sharpener is that it includes a diamond rod for sharpening serrated blades and a ceramic hone for serrated blades.
TIP: A handy sharpening tool for your pocket knife would be a good investment. Check out detailed guide on the best sharpeners for pocket knives in the article below:
3. A Strop For Honing Your Knives
A strop is used to put the finishing touch on an already sharp knife. This process is termed honing and can be the final step in the sharpening process of a knife or used on its own to restore the keen edge on the knife.
The best tool to use for this sharpening process is a leather strop combined with a light grit abrasive compound.
The strop is used in a similar action to whetstones, using the same angles used to sharpen the knife. Less pressure is used on a strop since the purpose is to straighten and polish the final cutting edge
Leather strops can be made in any convenient size, which means you can make large ones similar in size to your whetstones, or you can make smaller pocket-sized ones to carry with you wherever you go.
What Is The Best Tool Used In Sharpening?
The best sharpening tool will vary depending on who you speak to, but most knife and sharpening aficionados agree that whetstones make the best knife sharpening tool.
This is because the angle of sharpening is easily adjusted to any angle for the knife concerned. The edge you can achieve with this sharpening method is generally superior to most other sharpening tools.

What Material Is Best For Sharpening Knives?
Many materials are used in tools for knife sharpening, even within the whetstone category. Whetstones can be diamond plates, ceramic or glass stones, natural stone, aluminum oxide, or silicon carbide.
The best whetstone material for sharpening knives is Japanese water stones made from natural stone. The major disadvantage with these stones is the price, which puts them out of reach for most knife owners.
Diamond plates are the next best material to Japanese water stones and are considerably cheaper. Diamond stones have the advantage in that they retain their shape and do not require flattening as the other materials do.
TIP: Diamond sharpening stones are becoming a popular alternative to traditional whetstones. Find out what they are and how to take care of them in the article below:
What Tool Is Used To Sharpen Long Knives?
The best tools to sharpen long knives are whetstones. This is because the whetstones allow for the entire length of the blade to be passed across the stone in a single stroke.
There are other methods of sharpening long knives on whetstones, which involve sharpening sections of the blade at a time, but it is more difficult to maintain the same angle across the blade than using the single long stroke method.
Many sharpening systems, such as the Lansky Deluxe Sharpening System, have limited capability for sharpening long knives. On the other hand, Whetstones can be used to sharpen swords if you so desire!
While many tools are available for sharpening knives, the ones we have detailed can be considered the must-have tools for knife sharpening.
Other tools may offer more convenience but cannot compare to the quality of the edge on the knife when using whetstones for precision sharpness and edge repair, quality pocket sharpeners for in-field sharpening, and a leather strop to finesse the knife’s edge!
TIP: The cost and quality of the whetstones that you buy will often determine the success of your efforts when learning how to sharpen your knives. Check out the complete guide on how to choose a whetstone in the article below:
