+1 for the Lansky 5 stone kit. I sharpened a knife for my roommate sunday to shave your arm sharp in about 10-15 minutes and only got down to the 4th stone did not use the 5th one. Takes a little bit to figure it out but once you do it is an awesome kit. I am usually happy with the sharpness I get out of it just going to the 4th stone, but a friend of mine was jacking around with his knife and used the 15 degree edge and went all the way to the 5th stone and it was scary sharp when he was done. Highly recommend the Lansky.
