I have used the Lansky System for amost 25 tears. The best way to get a precisely angled edge on a blade. I do my kitchen knives at the smallest angle, my pocket and belt knives at the medium angle, and my bayonets at the steepest angle (I think that's 25 degrees, I don't have my Lansky in front of me).
For my el-cheapo chinese pocket knives I just use one of those pocket sized pull thru two sided deals that have a carbide angle on one side and ceramic on the other - Smiths makes them and Gander, Ace Hardware, etc sells them for less than 5 bucks.
