Looking for an easy-to-use knife sharpener that you can take with you on the go? Look no further than the Furi Ozitech Folding Knife Sharpener.
This innovative sharpener is designed to be simple and palm-sized, making it perfect for quick sharpening on the go. We were skeptical about this knife sharpener, expecting it to have average performance, but we were pleasantly surprised to realise it’s very very good at sharpening knives.
Thanks to its 8 stainless steel fingers bonded with crushed industrial diamonds, this sharpener is guaranteed to give your knives a quick and effective edge.
We did notice that after prolonged use, the fingers were losing their sturdiness, however we advise and were advised it would last around a year before you’ll need to replace it. A years worth of use for $52 is pretty good value in our opinion.
So whether you’re out fishing, camping, or barbecuing, or even simply at home make sure you have a Furi Ozitech Folding Knife Sharpener with you.
Key specs: Type: Electric | Automatic/Manual sharpening
- Automatic wheel for smooth edge knives
- Serated edge knives sharpened via manual method
- Effective and easy to use
- Not great for ceramic knives
Kitchen IQ’s KIQ50230 electric knife sharpener is the perfect way to keep your knives in top condition. Ideal for smooth edge and serrated edge knives, this sharpener is effective and takes the hassle out of keeping your knives sharp.
This versatile sharpener can handle both European and American-styleknives, as well as Asian double-beveled blades.
The ceramic edge guides each side of the blade evenly and smoothly against the interlocking wheels, so you can quickly sharpen even severely damaged blades back to their original condition.
We found this one of the easiest to use knife sharpeners. For smooth edge blades we used the automatic wheel and for our serrated blades we used the manual process. Both were efficient and effective.
This is quite an expensive knife sharpener and we don’t recommend it if you have ceramic blades, but for everything else, it’s best in class.
Key specs: Type: Electric | Automatic sharpening
- Multi-functional, can sharpen other objects not just knives

The Davis & Waddell Electric Knife Sharpener is a must-have for anyone who wants sharper knives. And even if you want to sharpen other objects this will do a great job.
This multifunctional device can quickly and easily sharpen both straight and serrated knives, as well as scissors and screwdrivers.
It’s designed for right-handed and left-handed users, making it versatile for everyone.
With stages 1 and 2 providing a coarser grind and stages 3 and 4 delivering a finer blade finish, your knives will be sharp in no time.
If you’re looking for razor sharp knives though, then this sharpener isn’t for you. We found it didn’t make our knives razor sharp just sharp. If you’re looking for fish filleting sharpness, then there are better options out there. But if you’re looking sharp cooking utensils, then the Davis & Waddell does a great job.

It’s easy to keep your knives sharp with the MasterClass 3 Stage Knife Sharpener.
This precision sharpener has three slots to quickly repair and sharpen damaged edges, with a tungsten steel slot to create a perfect ‘V’ edge and a crossed ceramic stone for final honing.
We loved the 3-stage process with this sharpener. The 1st slot is for reviving dull knifes, the 2nd slot is for shaping the blade and the 3rd slot is for sharpening it. It works well and is easy to do.
The ergonomically designed handle provides a firm grip and non-slip base, while the steady platform ensures accurate sharpening every time.
The only reason this sharpener isn’t higher on the list is because it didn’t make our knives as sharp as other sharpeners we tested.

Featuring both a 1000 grit and a 6000 grit side, it’s easy to get your knives sharp with this whetstone. We did find it was harder to use than other conventional sharpeners but if you prefer using a whetstone then this is an affordable and effective option.

But it’s safe, affordable and portable, ideal for taking around with you.
Knife Sharpener Buyer’s Guide
To help you with your knife sharpener buying decision, we have compiled a list of questions that potential buyers should ask themselves before making their decision.
What type of knife sharpener are you after?
A whetstone is a type of knife sharpener that is made up of two stones: a coarse and a fine. The coarse stone is used to establish the bevel angle and the fine stone is used to polish the blade. Most whetstones need to be lubricated with water, oil, or honing solutions to produce the best results.
When using a whetstone, it is important to keep the angle consistent. It is also important to make sure that you are always pulling the knife towards you, never pushing.
The pros of a whetstone knife sharpener are that it is a very versatile sharpener and it can be used to sharpen a wide variety of blades. It is also a relatively affordable sharpener. The cons of a whetstone knife sharpener are that it can be difficult to use, especially for beginners, and it requires a lot of practice to get the best results.
An electric sharpener is a knife sharpener that operates on electricity. It usually has two stages: the coarse stage and the fine stage. The first stage uses tungsten carbide or steel blades to sharpen knives, while the second stage can be used with diamond abrasives to hone them.
Electric knife sharpeners are easy-to-use compared to most other types of manual knife sharpeners because they have guides that ensure consistent angles throughout every use.
They also tend to work very quickly, but may not give as high-quality results as some other types of manual knife sharpeners.
A manual sharpener is a knife sharpener that does not require electricity.
Manual knife sharpeners are very versatile and can be used to sharpen a variety of blade types. They are also relatively affordable compared to electric knife sharpeners.
The downside of manual knife sharpeners is that they can be difficult to use, especially for beginners, and do require some practice to achieve good results.
What grit level does the knife sharpener have?
The grit level of a knife sharpener is the measure of the coarseness or fineness of its abrasive particles. Most knife sharpeners have either two or three grit levels: coarse, medium, and fine.
The coarse grit is the roughest and most aggressive of the three, while the fine grit is the smoothest and least aggressive.
When it comes to choosing a knife sharpener, it is important to consider what type of blade you will be sharpening. If you are sharpening a blade that is already quite dull, you will need a knife sharpener with a coarse grit level. If you are sharpening a blade that is only slightly dull, you will need a knife sharpener with a medium grit level. If you are sharpening a blade that is relatively new, but not very sharp, you will need a knife sharpener with a fine-grit level.
What size knives do you have?
The type of knife sharpeners available varies greatly depending on the width and length of your blades. Some types of manual or electric knife sharpeners can only be used for one specific blade shape while there are some which can be used across multiple sizes.
If you have different sized blades in your kitchen, it is important to consider what size of knife sharpeners they require before making this purchase decision as well as considering how much space they would take up if stored in an already small kitchen!
Knife Sharpener FAQs
What do professionals use to sharpen knives?
Professionals use electric knife sharpeners to keep their knives sharp. These are usually very efficient and can be used on a daily basis.
What is the best way to sharpen my knives?
There isn’t one “best” method of sharpening your blades, but there are some techniques that work better than others! If you want high-quality results, it’s important to remember many professionals use manual or electric knife sharpeners as opposed to whetstones.
When should I consider getting a professional service for my kitchen knives?
If your blades need serious sharpening or if they have been badly damaged (bent/chipped) then you may want to get them professionally serviced by an expert who knows how to restore them back to their original condition. Many knife shops or services offer this type of restoration.
What angle should the blade be at when I sharpen it?
There is no set answer to this question as different blades require different sharpening angles. However, most electric and manual knife sharpeners come with guides that will help you maintain a consistent angle throughout the sharpening process. This is important for achieving high-quality results.
Can I use a diamond sharpener on my ceramic knives?
It’s not recommended to use diamond sharpeners on ceramic knives as they are much harder than steel blades and can cause damage if used incorrectly. Instead, try using a honing rod or diamond steels specifically designed for ceramic blades.
Do knife sharpeners ruin knives?
No, knife sharpeners do not ruin knives. If they are used correctly and the angle is correct, there won’t be any damage done to your blades!
