i have a little "gismo" called an accusharp i found it in a local tackle shop and its just one of them you drag over the blade and it has 2 pieces of carbon or something inside shapped like a V and it does great for me it puts on an awesome edge but ive about wore it out all my friends have bought them to since i showed them mine it was only like $10 or so but its great if you cant use a stone ive destroyed more knives then i care to mention with a stone and im just really bad with them but that accusharp thing works really good and i was impressed with the edge it put on my knives and i have bald spots on my arm and cuts on my fingers to prove the edge it`ll put on a knife
