I got a Spyderco Sharpmaker for Christmas, and I REALLY like it. I used a Lansky turnbox ceramic kit for years, and it works well... but the Sharpmaker takes it to another level. The standard Sharpmaker comes with medium and fine ceramic rods. Add diamond rods and ultrafine ceramic rods, and you're set.
Messing around with my Benchmade 903 over the weekend, I was able to produce an edge that was splitting arm hair (a 10x jewelers loupe helps).
