Chef’sChoice AngleSelect 1520 – Best Overall
If you have both 15° Asian style knives and 20° American or European style cutlery, this machine has you covered. A toggle lets you choose between these two very popular angles so that you can maintain your edges on all of the straight blades in your kitchen.
You can also sharpen both single and double beveled knives, giving this model a great deal of versatility. It uses 100% diamond abrasive technology so sharpening will be fast, efficient and even. Your knives may even be better than new after using the AngleSelect 1520.
- Take your pick between 15° and 20° edges with a single switch
- Can sharpen both single and double bevel edges
- Diamond abrasive sharpening surfaces
- Use stage #3 setting to sharpen serrated blades
- Made in the USA (some parts imported)
- Pricier than some can afford. Be sure to check out my bargain pick below!
- A little larger than some more compact models, taking up more counter or cupboard space
Chef’sChoice 15 XV Trizor – Best 15° Model
If you happen to have a collection of 15° knives or want to convert your American or European 20° blades to a sharper 15°, then this is the model for you. In addition to using diamond coated grinders to refresh your edge with speed and precision, this three-stage electric knife sharpener will convert your knives into high-performance Asian-style cutlery.
For serrated blades, such as bread and tomato knives, you can use the final stage to polish them until they are even sharper than when you bought them!
For straight-edged blades, you can use this model to create the super durable and sharp Trizor® edge, or traditional single and double bevel edges. The advantage of the Trizor® edge is that it is a triple bevel that creates both durability and superior sharpness for the best of both worlds.
This is a true three stage knife sharpener. The first two stages use conical (burr free) diamond coated disks to remove the slightest amount of steel to create a new edge, followed by a stripping process in stage three to finish the edge to perfection. This is a machine for the aspiring home chef!
- Convert all of your blades to 15° for superior sharpness
- Use the patented Trizor® edge setting to get added durability without sacrificing sharpness
- Can also be used to sharpen serrated edges if used on polishing stage #3
- Works great on single and double-edged blades
- 3-year limited warranty
- Use for 15° blades, or those you want to convert to this angle only
- A bit of an investment – for serious home chefs
- Large footprint – you will want to set aside some space in the cabinets for storage.
Grocery Art 3-in-1 Sharpener – Multipurpose
If you are most concerned with finding an electric knife sharpener that will work on more than just kitchen knives, this model by Grocery Art is my top recommendation. You can use it to keep your kitchen shears razor sharp, in addition to cutlery, hunting knives, crafting scissors and even screwdrivers.
Another feature to love about this model is that it is small and compact enough to sit on the kitchen counter. The streamlined design and all black exterior make it blend in to kitchen décor. Anti-slip feet keep it secure while you slide your blades through like butter.
This model uses ceramic sharpening grinders, which honestly won’t last as long as diamond coated grinders in professional grade models. For low to moderate use, this may not be an issue. However, if you are on the “foodie” side of the spectrum looking to pay more for premium and longer lasting gear, consider investing in one of the Chef’s Choice picks listed above instead.
- Versatile – use on knives of all kinds, scissors, screwdrivers
- Compact and attractive design makes it great for the counter
- Inexpensive – great for a gift or for light to moderate usage
- Two stages for sharpening and honing all-in-one
- Easy to use design
- Ceramic sharpening mechanism is not as durable as diamond coated models
- Less powerful than other more professional grade models
- Cannot be used to hone serrated blades
LINKYO – Bargain Choice
Coming in at under $25, this model is a nice choice if finding a bargain is your top priority. This model by LINKO is designed to maximize ease of use for beginners. Each slot in the two-stage sharpening/honing system will properly guide your knife into the perfect position for the ideal edge.
One feature that I like about this model is that since each stage sharpens one side of the edge at a time, you can use it on either single or double beveled edges. The 20° edge will work for the vast majority of American and European cutlery.
If you are looking for an electric knife sharpener that covers the basics with a low price tag, this is your best bet.
- Great bargain – coming in under $25
- Extra easy to use with a helpful guiding system perfect for beginners
- 2 stage operation – sharpen and hone in a snap
- Use for single or double bevel edged knives
- Register this product for a one year warranty
- Probably not high-end enough for serious home chefs
- Blade slots will not accommodate scissors or thick hunting knives
- Cannot be used on serrated blades
Sharpening vs. Honing Knives
You may think you don’t need an electric sharpener. After all, you already have the steel rod that came with your set for sharpening your blades. However, turns out this is actually a honing tool. What is the difference?
A honing tool works by pressing the blade edge back to the center line, restoring the edge from the slight compression from regular use. It will keep your knife sharp, but only for so long. Eventually, you will need to sharpen your knife.
Sharpening, using a wet stone or electric knife sharpener, actually grinds away some steel on both edges of the blade leaving a fresh ultra-sharp edge. I hone my knives every 3-5 uses and only find myself needing to sharpen them a few times a year.
Knife Sharpening Angles – 15° or 20°?
There is a tradeoff between sharpness and durability of the edge. The more narrow the angle, the sharper the blade, however, this also makes the blade more delicate which means it will require more frequent sharpening to maintain the edge.
Most American and European knives come from the factory with a 20° edge. Frankly, for most home cooks, as long as you regularly hone your knife, this is plenty sharp for your needs. If you end up getting into applications that require even more precision, such as cutting sushi or making delicate garnishes, a 15° edge may come in handy.
If you are looking to purchase a knife with a 15° edge, look for Japanese knives. I will admit that although most of my knives are 20°, I do have a few 15° knives in my collection as well. The one that I find I pull out the most? A 15° boning knife that I use mostly for the delicate work of filleting fish.
Single Bevel vs. Double Bevel Knives
Take one of your knives out and take a close look at the blade. Chances are, you will see that both sides of the blade’s edge are slightly angled into a V shape. In America and Europe, this “double bevel” is the standard for most knives.
In double bevel knives, the angle of the edge is determined from the center line of the blade. For example, if you have a 20° double-bevel knife, the total angle of the edge itself is 40°. However, rest assured that the angle on your electric knife sharpener already takes this into account – you still want to use the 20° setting on your sharpener!
In some rare cases, some Asian style knives are a single bevel – but these are rare. If you happen to have some single-edged blades, be sure you choose one of the best electric knife sharpeners featured in this review that can handle single edged blades.
