I've been thinking about this and wondering what the real reason is behind these two blade styles. We've had several polls here and flat grind rules. Correct me please, but both slice, push and pull cut, and chop. It's on small knives, Dragonfly I believe, and on big ones, Manix. I think the hollow ground is a better platform for a Spyder Edge serrated blade but what is the main reason and function differences between the two? I don't think in a poll, we,ve had less tham 3% touting the hollow ground virtues. Hmmm.
