Not sure if this was mentioned on here before, but I bought one tonight at Dick's sports and it's a pretty neat pocket sharpener.



Only cost $12 and has a carbide and ceramic pull through sharpeners with a diamond stick type sharpener. It isn't perfect, but it's cheap and it works fine on both plain and serrated blades. It's pretty small too, only 3 1/4" x 1" x 3/8". I would check it out if you're looking for a cheap sharpener thats small and easy to use.
