The Chef’s Choice 1520 Angle-Select Diamond Hone Sharpener

chefs choice 1520

The Angle Select is capable of sharpening both Western style and Japanese style knives.  It relies on the same technologies as other Chef’s Choice sharpeners including a spring-guided system that helps hold the blade at a consistent angle as it passes through the sharpening wheels.

For those looking to sharpen both double bevel (Western knives) and single bevel (Japanese knives) this is a a great unit. But this flexibility comes at a price since it is essentially a 2 stage sharpener.

Here’s a quick video demonstration of the unit.

Our Chef’s Choice 1520 Angle Select Review

Let’s take a quick look at the pros and cons of this electric sharpener.


  • The unit performed quickly and reliably.  The spring guides allow you to quickly pass the blade through the wheels while maintaining a consistent angle.
  • The diamond abrasives of the first stage quickly remove any damage to the blade.
  • Operation of the unit is very simple.
  • Can sharpen a wide variety of knives.
  • The honing stage works very well for regular maintenance.


  • As with many sharpeners the 1520 requires you to reprofile all your blades at one angle.  In this case it’s 20 degrees for Western and 15 degrees for Japanese.  This often results in the removal of a good amount of blade material during the first sharpening.
  • Care must be taken not to run a one sided knives through the correct slots so as not to ruin the bevel.
  • If you’re only using Western knives lacks some of the capabilities of other models

Final Verdict:

For those with a wide variety of knives in their kitchen arsenal the Angle Select offers good flexibility.  It doesn’t offer the benefits of a traditional 3 stage sharpener, but it eliminates having to buy 2 different models for different styles of knife.

The guide system allows for little room for error, so once you’re accustomed to it, you can move fairly quickly through a number of knives.

There is some maintenance required, but nothing difficult. There is a magnet inside that catches the little metal shavings, and it does need to be cleaned periodically.

Overall we were fairly impressed with the 1520.  While it won’t take down the Smith’s adjustable from the top spot, it’s still a great little sharpener for those that need something that works quickly and efficiently.

1520 Angle Select Specifications

The measurements on this electric knife sharpener are 10”x 4.25 ”x 4.25”. It weighs approximately 4.15 lbs. A patented 3-Stage Angle-Select system and DiamondHone technology allows it to restore and recreate both 20-degree edges for American and European style knives, as well 15-degree edges for Asian style knives.

This product sharpens using a 3-stage technology. Asian style knives that require a 15-degree angle are sharpened using Stage 1 and Stage 3. To sharpen knives to a 20-degree angle, Stage 2 and Stage 3 are used.  The first two stages sharpen and hone the edges with 100% diamond abrasives, while Stage 3 uses a flexible polishing disk to microscopically polish the edge for a flawless, super-sharp finish.  It comes with a 3 year warranty.


Because you can damage your knives if used incorrectly, I would highly recommend reading the owner’s manual all the way through before trying it for the first time.

You should allow for 10-15 minutes to get a feel for how the sharpener works, what angles to use, and how much pressure to apply. Once you have an understanding of how it works, you can actually move fairly quickly.  The spring guided system eliminates any guesswork and allows for optimum control all the way down the length of the blade.

The guide system can even accommodate thicker knives and cleavers.

Sharpening is very quick and easy using the 1520.  Even with some particularly damaged knives we were able to proceed fairly quickly through the stages.  One knife in particular had some severe damage but was brought back to life in a little over 3 minutes.

Re-sharpening can be as quick as about ten seconds depending on if the knife needs to be sharpened or just honed.  The honing stage is impressive and put a lasting edge on our test blades.

I typically hone my knives quickly before using them and this unit is perfect for that although it’s a bit less convenient on the counter than a honing rod.  But for those not used to working with a honing rod this unit eliminates all worry.


Because this unit allows flexibility in the sharpening angle it can be used on a wide variety of knives including: chef’s knives, Santoku knives, bread knives, hunting knives, fillet knives, and pocket knives.

It is not recommended for ceramic knives, machetes, axes or scissors. It can sharpen ceramic knives, but the ceramic will wear down the diamond abrasive faster than a metal knife.

And because scissors have a 45-degree blade, grinding the blade to a 20-degree angle would take a lot of time and cause unnecessary wear to your new sharpener. Chef’s Choice does make scissor sharpeners, some of which can be found here.

It is capable of sharpening single and double bevel knives at 15 and 20 degrees.  It is also works on serrated edges. It cannot sharpen triple-bevel, criss-cross, or steeled edges.
