Best Knife Sharpeners – Buyer’s Guide
When you’re in the market for a quality and suitable knife sharpener, there are several key factors to consider before buying one:
Most decent knife sharpeners offer at least two different stages, generally one for sharpening and one for polishing.
However, there are also products that use a 3-stage system so you have to figure out whether you need all the extra slots or not.
For example, here’s what a 3-stage system includes:
- Stage 1 (sharpening stage) – Removes some of the metal on the blade to create a new, sharper edge
- Stage 2 (straightening stage) – Restores and straightens the existing edge of the knife
- Stage 3 (polishing stage) – Fine-tunes the edge, essentially getting rid of any burrs
But unless you have some high-end kitchen knives that require extra care, you’ll do just fine with a standard 1-stage sharpener.
Your budget will determine what kind of knife sharpener you end up with since as a general rule of thumb, electric sharpeners are that much more expensive than standard, manual ones.
Another factor that comes into play when forming the price of a given sharpener is the built quality and materials used.
Generally, more expensive options tend to be more durable and long-lasting.
But for the most part, just look for a knife sharpener that provides the most value for money like our top pick that sits on top of the list above.
The last thing you want when using your newly bought knife sharpener is to cut one of your fingers.
To prevent that, look for products that have comfortable, slip-resistant handles or an anti-slip base.
Thankfully, our list is full of quality and safe knife sharpeners that are encased and/or have a slip-resistant design.
However, if you need a knife sharpener for outdoor use you’ll need a super small and compact one, so all those fancy anti-slip features will most likely be non-existent.
In this case, just be extra careful when sharpening your hunting or survival knife since you’d have to prioritize compactness and lightweightness over additional bells and whistles.
Electric vs Manual
It’s entirely up to you to decide what type of knife sharpener do you need – a fully electric one or a standard tool by which you sharpen your knives manually.
- Minimal effort required
- More functions
- Intuitive to use
- Require electricity
- Bulkier and heavier
- More affordable
- More compact and lightweight
- Survival and hunting-friendly
- You have to be more involved
- Higher chance to cut yourself
Electric knife sharpeners have one main advantage is the hassle-free sharpening process as all that you have to do is hold the blade in place and the sharpener will do the rest.
Manual sharpeners, on the other hand, require more handwork (see what I did there?) since the sharpening motions will be manually done by you.
And as you might imagine the convenience of electric sharpeners comes at a price as they’re generally way costlier.
Nonetheless, go for whichever kind of sharpener suits your needs!
Frequently Asked Questions – Knife Sharpeners
In this section, we’ll focus on answering some of the frequently asked questions regarding knife sharpeners.
What is a Knife Sharpener Called?
There are many different names for knife sharpeners, depending on their type.
But here’s what the most common names for knife sharpeners (depending on their kind) are:
- Honing steels
Eventually, despite the name variations across the different sharpeners, they’re all eventually the same thing – knife sharpeners!
How Does a Knife Sharpener Work?
The way knife sharpeners work is quite simple – they remove tiny pieces of the metal on each side of the knife through abrasive material e.g. diamond abrasives.
This is done by utilizing 2 pieces of abrasive material forming a V shape so that you can give your blade/s a nice edge on both sides.
What is the Best Way to Sharpen Kitchen Knives?
The most optimal way to sharpen a standard kitchen knife is by using a manual knife sharpener such as a honing steel rod .
Alternatively, you might have to use sharpener steel rod that has a ceramic or diamond powder coating (that’s what differentiates it from honing steel).
The addition of this special coating means that you’ll be able to remove more metal that’s essential if your kitchen knife is hopelessly dull.
Here’s how to do sharpen your knife using a honing or sharpening steel:
- Grab the kitchen Western knife that needs sharpening
- Hold it against the sharpening or honing steel rod at approximately 22.5°
Note: Asian-style knives call for a greater angle – 10° to 20°
- Start swiping the blade up and down across the steel rod’s length
Note: Don’t press too hard as the knife’s weight will provide enough force
- Clean the now sharpened knife and rod with clean water
- Dry them using cloth so that you can also remove any leftover metal pieces
- Test the knife on a tomato – it shouldn’t crush it
What Degree Should a Knife be Sharpened?
The exact bevel angle that you should use for the optimal sharpening of your blade depends on its type and specific needs.
Regardless, here are a recommended bevel angles depending on the type of knife that you’re sharpening:
- Sport knives
- Hunting knives
- Survival knives
- Pocket knives
- Carving knives
- Chef’s knives
- Boning knives
- Kitchen knives
- Smaller-sized knives
- Asian cutlery (mainly Japanese)
- Fillet knives
- Sushi knives
- Paring knives
- X-acto knives
- Straight razors
- Razor blades
Then again, going for a bigger angle is recommended if you’d like your knives to have a more durable edge less likely to chip.
How Many Types of Knife Sharpeners are There?
There are 4 main types of knife sharpeners out there:
Handheld/Manual Knife Sharpeners
Manually-operating sharpeners can range from anti-slip base models that you place on a flat surface and ones that you hold upright in one of your hands.
These sharpeners are typically incredibly compact and lightweight, making them ideal for outdoor use since they don’t require electricity as well.
Electric Knife Sharpeners
This kind of sharpeners relies on electricity to automatically sharpen your blade – you just have to hold it in place.
Generally, electric knife sharpeners come with at least a 2-stage system that includes a sharpening and polishing stage.
They’re also dead easy to use and require minimal effort, although you’d need to have access to electricity to use them.
Honing / Sharpening Steel
Honing steel rods are meant to hone and fine-tune a blade, not so much as to sharpen it.
While sharpening steel rods provide better sharpening due to the diamond or ceramic (or both) abrasive materials used.
The idea of these steel rods is to maintain an already sharp blade as they won’t be able to bring a dull knife back to life.
Sharpening stones are one of the more old school and classic ways for sharpening a blade.
They’re typically made of several different materials (or a combination) silicon carbide, novaculite and aluminum oxide.
And some sharpening stones even add a diamond abrasive into the mix for a sharper edge.
How Often Should You Sharpen a Kitchen Knife?
This depends entirely on the type of knife and what you’re using it for.
But since you’ve asked, here are some pointers:
- Carbon steel knives – These require honing after each use
- Stainless steel knives – Should be honed once every 2 to 4 uses
Keep in mind that honing a blade on a regular basis will keep it sharp so that you won’t have to sharpen it in the real sense of this word that often.
In fact, knives that are regularly honed might require only 1 sharpening session per year or even 2 years!
What’s the Best Knife Sharpener for Hunting Knives?
Based on the lots of superb reviews online, reputation, price and overall perceived quality, our recommended knife sharpener for hunting knives is the Work Sharp Guided Field Sharpener .
It utilizes a 3-position ceramic rod, diamond plates and a leather strop to give your knives a razor-sharp edge.
You’re also getting two angle options – one (20°) for sharpening and one (25°) for honing.
Last but not least, this hunting knife sharpener is ridiculously compact and lightweight so you can take it anywhere you go.
So there you have it folks – based on overall rating, price, reliability, ease of use and value for money, the absolute best knife sharpener out there is the KitchenIQ 50009 Edge Grip 2-Stage Knife Sharpener .
This particular sharpener is also incredibly compact and lightweight, making it survival-friendly.
But hey – you might prefer the convenience of electric knife sharpeners (especially if you intend to only use them at home) and that’s perfectly okay.
