I just want to start by saying this is my first experience with any kind of electric knife sharpener. That said, one of the most impressive traits about the Work Sharp MK.2 is just how user friendly it is. Work Sharp made life especially easy with the online instructional videos, and I highly recommend watching them if this is your first time with this type of sharpener.
Starting off, a couple of the features on this sharpener that I like the most are the front edge guide and the dual angle guide. The angle guide allows you to change the degree angle between 20 and 25 degrees, depending on the type of knife you're using, with just the flip of a switch. Outside of guiding hunts, I also own a restaurant, so I was able to try out the 20 degree angle on my kitchen knives. The front edge guide takes the guesswork out, easily allowing the user to follow the blade angle and maintain evenness while sharpening. Another nice feature on the angle guides is the leather lining on the sides. I have a lot of outdoor knives that are heavily used that I don't mind being scratched up, but I also have some that I want to keep in great aesthetic condition, and the leather lining works great to protect from scratches.
The belt system allows the user to sharpen a wide variety of blade types, including pocket knives, kitchen knives, serrated blades, axes and tools, and more. The design also allows for very fast band changes, which includes 3 different band types ranging from grinding to precise sharpening. The MK2 also has 2 speed settings, one for sharpening and one for heavier grinding.
Throw in a 3 year warranty and a price around $100, and it's very hard for any outdoorsman to find a reason not to own one!
