Check out the chefs choice electric sharpener. I have 2 friends who use them and both sharpen my hunting knives and they come back really sharp. Plus it only takes about 5 minutes. There model has 3 slot. The first one is not necessary if your knife is maintained. Just the last two (I think the last one is s strop). Either way it is easy to use and does a good job. The last time I read the reviews after a google search there were several web sites that said it was one of the best home use electric sharpeners.
