One company convinced a huge share of American home cooks to abandon their knives’ factory edge. Chef’sChoice pushed a narrower 15 degree angle instead of the usual 20. Its Trizor XV knife sharpener is the machine most people know it for.
The brand’s electric lineup runs on one idea. Motorized diamond wheels sit at a fixed angle. Anyone can get a consistent edge without freehand skill.
That promise built a loyal following. It also created real confusion about which model does what. This guide breaks down the real Chef’s Choice knife sharpener lineup.
What Actually Matters in a Chef’s Choice Knife Sharpener
Angle choice is the first thing to understand. A steeper 20 degree edge holds up longer under hard use. The 15 degree edge Chef’sChoice favors cuts more cleanly but wears faster.
Stage count matters almost as much. A two stage machine shapes and refines an edge. A three stage machine adds a polishing or stropping pass that most owners say makes a real difference in finish.
Metal removal rate is the tradeoff nobody advertises. The manufacturer lists diamond abrasives across every stage. Diamond cuts fast, so a first pass on a factory edge takes off more steel than most buyers expect.
Housing material also matters over years of use, not just the first month. Several Chef’sChoice models use plastic front housings around the sharpening slots. That plastic is where wear tends to show up first.
Warranty length is worth checking model by model. Coverage differs across the lineup, and a longer warranty is a small hint about how much confidence the maker has in a given machine’s motor and housing.
Deciding between two stage and three stage often comes down to the knives already in the block. A kitchen full of Western made knives at a factory 20 degree edge usually does fine on a two stage machine. A kitchen leaning toward thinner, more acute edges tends to get more value from the three stage system.
Price band is the last piece. A two stage Chef’s Choice sharpener typically lands around $135, while the flagship three stage model runs closer to $220. That gap tracks the extra stage and the angle conversion, not just branding.

Chef’sChoice Trizor XV
Best Overall
Three stage electric | 15 degree conversion | 100 percent diamond abrasives | around $220 | 3 year warranty
The Chef’sChoice Trizor XV is a three stage electric sharpener built around the brand’s signature 15 degree edge. Stage one shapes the edge with 100 percent diamond abrasives. Stage two refines it, and stage three polishes it to a finished bevel.
The manufacturer lists a full pass at around one minute per knife. Flexible spring guides are meant to hold a steady angle from heel to tip. It handles both straight and serrated blades, and it carries a three year limited warranty.
Owner reviews repeatedly mention consistency as the standout trait. Buyers who kept the machine for a year describe results that stayed just as sharp as the first week. Angle and pressure did not drift with repeated use.
This model is for cooks who want a narrower, more aggressive edge. It suits anyone willing to trade some steel for that finish. It is not for anyone who wants to keep a knife’s original factory angle intact.
Pros
- Consistent results that hold up over a year of use
- Handles both straight and serrated blades
- Three year limited warranty
- About one minute per knife
Cons
- Aggressive first pass removes more steel than expected
- Plastic front housing can chip under heavy pressure
- Some owners report motor power fading after years of daily use
Chef’sChoice Model 320
Best Budget
Two stage electric | 20 degree factory angle | fine and micron diamond abrasives | around $135
The Chef’sChoice Model 320 is a two stage electric sharpener. It keeps the standard 20 degree factory angle instead of converting to 15. Stage one uses fine diamond abrasives, and stage two uses finer micron diamond abrasives.
This is the Chef’s Choice knife sharpener to buy when the Trizor XV feels like overkill. It skips the polishing stage and the steeper price tag. It sticks with the angle most factory knives already carry.
Owner reviews describe it as reliable for routine touch ups rather than heavy restoration work. It suits a household that sharpens a handful of kitchen knives every few weeks. It is not built for anyone who wants to relearn a knife’s edge angle.
Pros
- Reliable for routine touch ups
- Keeps the standard factory 20 degree angle
- Lower cost than the three stage flagship
Cons
- Not built for heavy edge restoration
- Skips the polishing stage found on the Trizor XV
The Model 4633 Trap
Chef’sChoice sells a Model 4633 AngleSelect sharpener alongside the Model 320. Shoppers regularly assume it is another electric option. It is not.
The 4633 is a manual diamond sharpener with no motor at all. That distinction matters for anyone comparing prices across the lineup. A manual model will always cost less than an electric one.
It also demands hand control that the electric machines are built to remove from the process. Read product listings carefully before buying. The word to look for is whether a motor is mentioned at all.
Model Naming Confusion
Chef’sChoice’s own product pages list the flagship machine under more than one name. The same sharpener shows up as Trizor XV, Model 15, and Model 15XV. It depends on which listing a shopper lands on.
Retailer listings compound the problem. Amazon titles reference 15XV EdgeSelect. Other retailers use Trizor XV alone, and the specs underneath stay identical every time.
The EdgeSelect name adds another layer. Chef’sChoice uses it as an umbrella term for its diamond sharpening system across several electric models, not just the flagship. That makes it a system name, not a specific model.
The safest way to shop the lineup is by stage count and angle, not by model name alone. A three stage, 15 degree machine is the flagship regardless of which label sits on the box.
Mistakes to Skip
Do not buy the Trizor XV expecting a gentle touch up tool. It is built to reshape an edge. The first pass on a factory knife will remove more metal than a honing rod ever would.
Do not assume every Chef’sChoice sharpener with diamond in the name is electric. The 4633 proves that assumption wrong. A quick look at whether a power cord is pictured settles it fast.
Do not press hard against the plastic guide housings on any model in this lineup. Consistent light pressure protects both the housing and the edge. It is the difference most long term owners point to.
Do not shop by model name alone given the naming overlap across this lineup. Confirm stage count and edge angle on the actual product page before buying. Those two numbers tell the real story every time.
The bottom line: the Trizor XV earns its reputation as the Chef’sChoice flagship. It suits cooks who want a genuinely sharp 15 degree edge and do not mind the metal it takes to get there. The Model 320 is the better call for anyone who wants to maintain a standard factory edge without spending flagship money.
Either way, treat the naming on the box as a rough guide, not gospel. Match stage count and angle to what the knives actually need. The right model in this electric sharpener lineup becomes obvious once those two numbers are clear.
FAQ
Is the Chef’sChoice Trizor XV worth the extra cost over the Model 320?
It is worth it for cooks who specifically want the 15 degree conversion and the added polishing stage. It is not worth it for anyone happy with a standard factory angle.
Does the Model 4633 replace the Model 320?
No. The 4633 is a manual sharpener and the 320 is electric. They are not interchangeable despite sitting near each other in price.
Will a Chef’s Choice knife sharpener remove too much metal from my knives?
The 15 degree models remove noticeably more metal on the first pass than a 20 degree machine does. Routine maintenance passes after that first conversion remove far less.
How long does a Chef’sChoice electric sharpener typically last?
Owner reports vary, and Chef’sChoice does not publish an expected service life. Handling the unit gently, especially around the plastic front housing, appears to matter more than any single spec.
How much does a Chef’sChoice knife sharpener cost?
Budget for around $135 for the two stage Model 320. Budget closer to $220 for the three stage Trizor XV, and expect the manual 4633 to sit below both.
Can I use a Chef’sChoice sharpener on serrated knives?
Yes. Both the Trizor XV and the Model 320 include guides rated for straight and serrated edges, according to the manufacturer.
What should I do between full sharpening sessions?
A honing rod keeps an edge aligned between sharpenings and delays the next full pass. Our rod technique breakdown covers the grip and stroke that actually work.
