We bought the Chef's Choice Trizor XV EdgeSelect in October 2021 to test it out. We have been using it in the Healthy Recipes 101 kitchen ever since, along with a few others. Among the electric sharpeners we’ve gotten our hands on, this one is easily our favorite. 

The device really works. Our test knives came out keener than they were fresh out of the box. It is a bit loud, and re-edging takes a few minutes more than advertised, but the sharp and strong edge was worth it for us. The only improvement we could ask for would be more angle options.

Chef's Choice Trizor XV: The Specs

Item weight: 4.19 pounds

Dimensions: 10 x 4.25 x 4.25 inches

Type: Electric  

Wattage: 75W

We read the instructions thoroughly and tested the device out on two different chef’s knives. We also noted the time it took to complete a session, the device’s temperature after sharpening, and how much noise it made.

Versatility: Re-edges and Sharpens to 15 Degrees

The Chef's Choice Trizor XV will work on nearly any type of knife in the kitchen: chef’s knife, utility knife, cleaver, etc. 

Curiously enough, it says in the User Manual book that the device sharpens to a 14-degree bevel angle, as opposed to the 15-degree angle claimed on Chef's Choice's website, not to mention everywhere else. We contacted the brand who confirmed the sharpening angle to be 15 degrees, but offered no explanation for the discrepancy.

Regardless, the device does an excellent job of sharpening our 15-degree knives. Its strong motor can also reshape the edges of larger angles — it was able to give our 20-degree knife a finer, yet more durable edge!

Of course, each edge angle has its pros and cons. Unfortunately, this Trizor device doesn’t let you pick and choose — the sharpening wheels are fixed, while the spring guides don’t give much room for adjustments. If you wish to keep the original edge angle on your 13-degree fillet knives or 25-degree cleaver, you may have to consider the Work Sharp Ken Onion or a set of whetstones.

Like many electric sharpeners, the Chef’s Choice Trizor XV has two slots for each sharpening stage. Each slot works on one side of the edge at a time. Though it takes a little more time this way, it’s a big benefit because you won’t need a separate set of stones for your santoku, nakiri, and other single-bevel Japanese knives. Plus, it self-aligns the blade; your hand doesn’t need to be perfectly in line with the grinding wheel. 

Of course, you do still have to be careful not to sharpen your single-bevel knife on the wrong side.

While it won’t sharpen the individual teeth, the unit’s stropping disc does a fine job of giving your serrated blades a keen edge. If you’ve been wondering how to hone the single-bevel serration on your bread knives, this device is the answer.

Sharpness: Outperforms Brand New Knives

We’d read a lot of positive reviews before buying the Trizor XV, but were still shocked at how effective it is.

We started our sharpness test with a 15-degree chef’s knife. It’s one we use regularly in the kitchen, so it was properly maintained but had gone a few days without honing. In a kitchen as busy as ours at Healthy Recipes 101 where we cook 6 hours a day, 5 days a week, this was enough to blunt the edge from Level 8 to Level 6-. 

The first round of sharpening with the Chef’s Choice took 40 seconds, or one swipe through each slot plus an extra swipe through the stropping stages. That brought the knife back to Level 7. It had no problem cutting a lemon or making thin slices through a ripe tomato in one single draw. 

Another 30 seconds of sharpening and the knife was able to slide smoothly through raw chicken breast with skin.

Regular honing takes 20 - 30 seconds at most. Usually, that’s all you’ll need.

To bring our knife to Level 9 and make it able to cut through a piece of beef tendon in one motion, we spent a total of 2.5 minutes. That’s roughly 5 swipes on each slot. For comparison, it would take at least 15 minutes to reach the same level with a set of stones. The Chef’s Choice did it quickly and without all the mess.

We were skeptical about Chef’s Choice’s claim that the Trizor XV can convert a 20-degree edge to 15 degrees. So we put it to the test with a 20-degree knife whose edge was destroyed to uselessness with sandpaper. To our delight, it did exactly as the company said. The knife came out even sharper than when it was out of the box — it was able to cut through a beef tendon in one single draw after sharpening. The new edge literally shined, much to our amazement.

The full process did take twice the number of swipes suggested by the user guide (40 vs 20 through each slot on the first stage) to reset the edge. That was for a thin stamped stainless steel knife. If yours are forged high-carbon steel blades, expect to add about a dozen more swipes.  

The first re-edging session takes about 5 to 7 minutes. After that, you can effortlessly get a sharp, durable edge on your knife within 20 - 40 seconds. Its results are comparable to those produced with a set of whetstones, but with a fraction of the time and effort.

Noise: Loudest Mode Comparable to a Hairdryer

Many Amazon comments reported that the Chef’s Choice was loud. So we used an Apple Watch to measure the noise level and compare it with the other electric sharpeners we had on hand.

When not actively grinding, the machine was rather quiet at 61 dB — the same range as an average conversation. But on operation, its noise range was higher than the advertised “between 65 dB and 75 dB.”

The second and third stages — the ones you’ll use most often, worked at 69-79 dB.

The first and coarsest stage was the loudest. It came in at 82-87 dB, about the same level as a typical hair dryer. It’s slightly quieter than the Work Sharp Ken Onion (88 dB) and the Presto (89 dB), but the sound can still be intimidating for first-timers. Thankfully, you’ll only need to use the coarse stage sporadically. 

Safety: No Worries

Despite its strong electric motor, the Chef’s Choice Trizor XV is safe to use. Its plastic angle guides cover the sharpening discs, leaving only a small slot for the blade to fit into. 

The device is bulky, but it has a low center of gravity.  It’s heavy and has suction-cup feet that keep it in place. It’s not something your cat will push off the countertop.

The motor does heat up to a noticeable degree. With its heavy weight and strong feet, you can sharpen without using your hand to stabilize the device. But even if you do hang on, there’s no real risk of burning. 

We measured the temperature after 10 minutes of constant sharpening and the highest it reached was 38°C  or 100.4°F. This is about the body temperature of someone with a fever. At worst, it may cause mild discomfort if you have sensitive hands.

Ease of Use: Small Learning Curve

With everything incorporated into one single device, the Trizor XV is very easy to use.

Setup is a breeze: Place the device on a flat, clean surface, plug it in, press the button to turn it on and you’re good to go. The hassle-free setup is why we recommend this for most home cooks over the Work Sharp Ken Onion; while the latter offers more flexibility, it also has more parts and is trickier to set up. 

If you’re a new user, an electric sharpener can feel a bit intimidating. It may help to pull your knife through the fine slots a few times to get the feel before sharpening with the coarsest stage. 

Remember that you should NOT apply pressure or shake the knife. Pull it steadily through at 1 - 1.5 inches per second and the Trizor XV will do all the hard work for you. With the spring guides, it’s more difficult to do it wrong than right. 

If you sharpen a knife with a bevel angle greater than 15 degrees, the removal of material will be obvious on the blade. Keep calm and run your knife through the first stage until the edge-setting is completed. Then, work on the finer stages until the new edge gets smoothed out. It takes some time, but don’t worry, it’ll work.

Other than during re-edging, we couldn’t find a way the device can scratch your blades, as some reviews have claimed. The plastic spring guides fitted well for both of the chef’s knives we tested. The blades had different thicknesses, but we didn’t see any blemishes on either one after sharpening. To be extra safe, you can clean the guides and the discs with a thin, dry brush to remove any hard particles that could cause scratching.

Storage and Maintenance: Simple

While it isn’t as light and handy as a pull-through sharpener, the Chef’s Choice Trizor XV comes in a simple, one-piece design and is not a pain to store.

It’s just a bit thinner than a loaf of sandwich bread, so your Chef’s Choice Trizor XV may end up living on your kitchen countertop or island if you have the space. If you don’t sharpen your knives so often, it will also fit snugly in a drawer or on a shelf.

Other than the working section, which can be cleaned with a dry, thin brush, its body is smooth and free of tricky nooks and crannies. A gentle wipe with a dry towel should be enough to keep it clean. 

The Verdict: Should You Buy the Chef’s Choice Trizor XV Electric Sharpener?

The Chef’s Choice Trizor XV is a highly effective and powerful sharpener. It makes the sharpening process quick and effortless, and while the price is steep, we’d say the device pays for itself quickly enough. 

 Buy It If 

  • You want professional-level sharp knives sans the hours on whetstones
  • You’re looking for a single device that can answer most of your sharpening needs
  • You have 20-degree knives but prefer sharper edges 
  • You have single-bevel knives
  • Convenience and time-savings are important
  • You want quality and can make the investment

The unit’s main limitation is the lack of choice in terms of edge angle. Its high price tag can also be discouraging to those on a budget, in which case, we recommend looking into manual sharpeners such as the Kitchellence or Cubikook. 

Not Your Best Choice If 

  • Your knives come in different edge angles and you prefer to keep them that way (in which case, check out the Work Sharp Ken Onion)
  • Your knives have large chips, dents, bends, or major blade damage to fix
  • You’re on a tight budget
