Sharpening Technology
All 3 sharpening slots have spring-loaded knife guides that are preset to a 40° angle (20° on each side) to help users maintain the correct sharpening angle.
It uses Edlund's Easy-Track Guidance System, which is designed to quickly sharpen blades at exactly an 11° angle (steeper than domestic knife sharpeners). The motor has 1 ½ amps of power and runs at 1550 rpms, but it will shut off automatically when too much pressure is applied to the guidance system in order to protect the knife from excessive wear.
Description of Stages
The 1st stage is electric and has the most abrasive disk to raise a burr and create the 1st bevel edge. The 2nd stage is manual and has a small butcher's steel to steel the edge and create micro sharp serrations in it. The 3rd Stage is electric and has a flexible stropping disk to polish/straighten the blade and create the 2nd bevel. The 3rd stage can also be used to sharpen serrated knives.
The 1st and only stage is electric and quickly sharpens the edge to an 11° angle.

It has a simple rectangular design with an all stainless steel housing and contains no magnets. The knife guidance module is removable, so it is easy to clean, and both the knife guidance module and the grinding wheel assembly are replaceable.
Safety Features
There is a plastic cover over each of the rotating disks to protect your hands during operation.
It is NSF certified, the width of the knife opening is only 3/16", and there is also a lighted on/off switch to indicate when the motor is running. Additionally, an interlock switch won't allow the machine to operate until the guidance system is properly in place.
