I have quit a few Benchmades and the warrenty's all say that Benchmade won't sharpen the serrated part of the blade in their lifesharp service. I don't see why, because plenty of other knife companys like Spyderco cover their serrations. I have a hard time sharpening serrated blades and would probably only use the lifesharp service for this purpose. I just think that for the price they charge for their knives they could at least have a reasonable lifesharp service.
