I have never used the ceramics although a lot of people I know use them...  I have a good Arkansas Stone and a good steel, which took some learning to use effectively.  
I always sharpen my knives before I go into the wilderness, and do not carry a sharpening device with me.  I have never had a problem with a dull knife while camping or cleaning fish.  
My old wooden handled Rapala is a 9" I believe and is still easy to sharpen...  it cleaned a nice bunch of crappie last week as a matter of fact ;D
