Knife sharpener uses

The Chef’s Choice 1520 is one of the most advanced sharpeners on the market with the ability to handle serrated blades, traditional Japanese cutlery and even Santuko knives. This is alongside the European and American settings that can be set and monitored from the easy controls.

Because of the precision sharpening power of the Chef’s Choice 1520, you can actually use it as a tool to shave down your knives for sharper edges. It can handle cheap knives or branded, expensive knives just the same.

Fine grinding capabilities that come from the diamond abrasives give you the ability to completely provide a finish for your knives even if you sharpen them with another tool. You can also use the precision of the 1520 to change the angle on a knife – for instance, changing a 20 degree knife to a 15 degree micro bevel.

The Chef’s Choice 1520 can be used to bring back knives from the dead. The cutting wheels are especially aggressive on dull blades, and many reports have been made of the 1520 completely restoring old sets of knives that had not been used for years.

Care and maintenance

In order to ensure the longest life and best performance of the Chef’s Choice 1520 knife sharpener, the following care and maintenance tips should be followed.

  • Follow the manual directions closely for the different types of knife blades that you will be sharpening. The details are a bit different depending on the type of knife that you are trying to sharpen. These are the only directions that should teach you how to sharpen a knife using the 1520.
  • Pay special attention to Granton type blades and knives that contain Damascus steel.
  • Never take the 1520 to a third party repair shop. Make sure that you take advantage of the factory technicians that EdgeCraft maintains if you have a problem with your unit.
  • Take special note of the number of pulls that your knife will need for optimal sharpening. Do not oversharpen.
  • The polishing disks of the 1520 can be easily cleaned through the actuation of the rear lever of the unit. Use this built in cleaning unit by turning the unit on, holding the lever for 3-4 seconds to the right, then to the left. Use this technique only if the white disks within the unit are noticeably darkened.
  • Sharpen knives at the recommended speed, and keep a constant rate throughout the process.
  • Do not ever stop the blade motion when the knife is touching abrasive disks.
  • The knife blade edge should always be touching the abrasive disks as you withdraw the knife from the 1520 guiding slot.
  • Learn how to visually locate burrs in the edges of your knives to determine when a knife has been sufficiently sharpened.
  • Do not put more pressure than necessary to let the knife touch the abrasive disks. Excessive pressure can shorten the life of the unit and create possible safety hazards.
  • Modify the way that you sharpen over time to maintain the life of the polishing disks.
  • Clean the 1520 only with a damp cloth.
  • Remove metal dust from the unit once every year by taking out the cleanout cover from the bottom of the sharpener.

Safety Tips

In order to ensure the safety of the Chef’s Choice 1520 knife sharpener unit and people around it, the following tips should be followed.

  • Do not use the unit outside.
  • Do not use third party attachments with the unit.
  • Do not operate the unit if it has been damaged in any way or if the cord is serrated.
  • Make sure that the knife blade is fully cleaned before it is inserted into the 1520.

  • Do not come into physical contact with any moving parts on the 1520.
  • Always make sure that the 1520 is used on a stable surface.
