(4 out of 5 stars) Good!

Every good cook has heard the phrase, “a sharp knife is a safe knife.” Dull knives have a much higher chance of slipping. A knife that cuts precisely, cleanly and with fewer passes has a lower chance of causing accidents. There are a lot of options ou there for sharpening your knives. Traditional sharpening stones, steel honing rods and an endless array of sharpening systems exist to get the job done.

Having a lot of options is good, but it can also make it difficult for you to make the right choice. The Chef’s Choice 316 Diamond Sharpener (See Lowest Price) is an electric sharpener specifically for knives with a 15° edge. It was designed to put factory-sharp edges back on your Asian-style knives, Chinese-style cleavers and single-bevel Japanese blades. Here are a few of the strengths and weaknesses of this sharpener:

>> See Lowest Price <<


  • Good value for the money
  • Can sharpen serrated blades
  • Makes sharpening fast and easy
  • Takes the guesswork out of getting a perfect, 15° edge


  • Only sharpens to a 15° edge
  • Only has two sharpening stages
  • The safety guard may prevent sharpening the full blade length on a few knives


The Chef’s Choice 316 has two stages to sharpen your knives to a 15° edge. Both stages use a fine diamond abrasive. Diamond is the hardest substance in the world and makes for a great sharpening surface that won’t quickly wear out. The first stage hones the edge, while the second uses an ultra-fine surface to polish the edge. This works well for most culinary blades, but a three-stage system may be necessary for older and extremely dull knives.


This sharpener uses high-precision elastomeric-angle guides. The guides remove any guesswork and potential for user error. This allows you to always get an exact 15° edge on your blades. You can make them just as sharp as they were from the factory again. The sharpener is fast and easy-to-use. Your dull, well-used kitchen knives can be sharp within a couple of minutes. Re-sharpening a knife can be done in as little as 15-30 seconds.

The Chef’s Choice 316 Diamond Sharpener can be used for single-sided, double-bevel or even serrated blades. On double-beveled knives, the sides are sharpened separately. This works well for Japanese knives, Chinese cleavers and some modern European knives. Single-bevel, Japanese knives can also be sharpened just on the front side of the blade.

The Chef’s Choice 316 Diamond Sharpener is fine for use on chef’s knives, Santoku knives, bread knives, hunting blades, fillet knives and pocket knives. The great thing about an electric sharpener is that there is very little skill involved. Sharpening a knife the old-fashioned way is an art form. With the model 316, you just let the machine do all of the work. The sharpener can handle straight edge and fine-edge knives.

This electric sharpener measures 8 1/2″ X 5″ X 4″. The weight is right around 4 pounds. The sharpener is well constructed and has a quality feel to it. It’s an attractive unit that will look great in any kitchen without taking up much space. The light weight makes it easy to move around. The unit is available in either black or red to better match your kitchen’s decorum. The Chef’s Choice 316 Diamond Sharpener comes with an instruction manual and has a one-year limited warranty.

Final Thoughts

The Chef’s Choice 316 Diamond Sharpener offers good value for your money. The cost is very reasonable. The construction of the unit seems very solid and built to last. The diamond-abrasive material should last for years of use. The Chef’s Choice brand is a well-trusted, reliable brand. This model certainly lives up to that reputation. This is an excellent choice for a sharpener, but may not meet every chef’s needs.

This Chef’s Choice 316 Diamond Sharpener is meant for honing and keeping your blades maintained. It is not as good for bringing a really old or extremely dull knife back to life. Those require the removal of more material to bring back the edge. This model has only two stages that are best for keeping those knives sharp before they become too dull in the first place.

The Chef’s Choice Model 316 is a great choice for the culinary artist who prefers Asian-style blades. If you use a mix of Asian, European and German blades without a 15° edge, then you may need to purchase a second sharpener or find a choice that handles more blade angles. It can be used on any knife if you wish to change the factory edge angle to 15°. If that’s your preferred edge type, then it should serve you well.
