Spyderco TriAngle Sharpmaker, Sharpening Kit w/DVD, C204MF
[C204MF]

Great system for keeping sharp knives sharp, diamond rods are a must for anything but light maintenance as metal removal is very slow on the ceramics. Longer knives and tougher steels are this systems downside Imo. (odd tip, you can elastic a lansky diamond stone or something similar to one of the rods to match the angles if you need to get past some deep chips or reprofile a bit before moving down through spydercos rods)
