I have seen them, but just am not a fan of serrations. I always found them a pain to sharpen. One of these days I gotta get a spyderco sharpmaker, then maybe that will change. I use my sebenza for everything, from opening boxes, to whittling, and whittling with serrations just does not work. But they are a big hit as there are companies out there that primarily deal in serrated knives. I am sure if you want a serrated knife, CRK makes some of the best.
