Sharpening advice

[Webs]

Need some advice on sharpeners. Just got a BM 551S, my first combo serrated/plain edged knife. The place that sold me the knife carries Spyderco sharpening system(s)-I can't remember if it's the 204(?) system that I think I've come across in some of the posts. Ideally, looking for a sharpening sytem that will really take care of the serrated edge as well as work well for a variety of steels, including D2 and 10V. Any experience/insight is appreciated.

The 204 is an excellent system, even comes with a video to teach you how to use it. It is specifically designed to sharpen serrations, and would work fine on your Benchmade. I would recommend supplementing it with a diamond benchstone or two for reprofiling. The 204 is great at touch-ups and polishing, but practically useless for removing lots of metal. That's where diamonds really shine.
