The new MK2 from Work Sharp is the best belt sharpener I've used. Easy to change belts and adjust the angles for your field knives and kitchen knives. The new blade guide is great no more switching things around to get the angle you need just flip a switch. If your sharpening an ax or blade on some hedge tripper go ahead and put your Work Sharp on the second speed and really take the edge off. I used this and touched up all by blades for the upcoming year and it worked fantastic now when I'm out in the field I can use my diamond sharpener to touch them up or swap out knives and just bring them back to the trailer and sharpen them on the Work Sharp.
So far I don't have any dislikes with the product but as I use it I'm sure I'll find something.
