All 3 sharpeners are based on the original design of Wicked Edge. They all must be secured to either our Aluminum or Granite Base, or can be secured directly to a workstation. They all come with a pair of our 100/200 Grit Diamond Stones and 400/600 Grit Diamond Stones.  The WE100 is ideal for anyone new to knife sharpening and wants the ability to upgrade the system as desired. It utilizes the Standard Vise, has an angle range of 15 - 30 degrees per side, and the angle adjustment is in 1-degree increments. The WE120 is our most versatile sharpener, perfect for those who have a wide range of blades in their collection. It also has the Standard Vise but includes a riser block that extends the angle range to 13 - 35 degrees. It also includes the micro-adjusts that allow you to adjust the angles in 0.05-degree increments.  The WE130 is designed for those who sharpen regularly and want the versatility of the widest angle range with the quick operation of the Cam-Lock Vise. It offers the same angle range and adjustability as the WE120, but it includes our Cam-Lock Vise which is operated with a lever, making it quicker to operate. This vise was designed to keep your knives centered and provide a more secure grip on fully-flat ground blades.
