Pros: Effectiveness, Overall Quality, Ease of Use
Cons: Durability
SOG made, They Know Blades!
I bought this for my wife because I got tired of being called "in to service" every time her pocket knife or kitchen knives get dull. Simple, easy to use. Mounts well on our cutting board in the kitchen and after only a few strokes, she has a razor sharp knife! We're both happy. Cons(?): Over all body is plastic, would pay more for more metal but it doesn't feel cheap, just me wanting it metal.
