In my opinion, the best way to sharpen a knife is to buy a good set of bench stones (Norton, Spyderco, Arkansas etc..) and take the time to learn to use them well. I also use a piece of 3" x 18" leather to finish strop the blade.
The best info on the web about sharpening a knife can be found on Don Foggs excellent website. www.dfoggknives.com
You will have to get there and search for the area about sharpening, but it will be worth the search!!
