Just yesterday I bought Smith's 3-in-1 sharpener. Very, very good. I was having trouble getting my variety of knives shaving sharp. This system has a diamond stone, a carbide shaper, and ceramic rods that all fit in a tidy little case. I was AMAZED how well it works. I bought it from our local Sportsman's Warehouse for $19.95 and figured I'd try it and return it. I mean, how good could it be?

It's so good, I'm buying another one or two. Check the reviews at sites like Cabelas.
