I just bought a pack of the 200gr. screw-in model Terminators from Bill at Zipper bows. Out of the pack they had a decent edge but not what I would consider hunting sharp. I am horrible at sharpening anything but it was very easy to get these to pop hair with just a few strokes on a flat stone. They are dead silent in flight and they fly just like my field points, oh and they are built like a tank. I'm no expert on big game animals but I would not hesitate to shoot anything with fur or feathers with this head. It's not a professional review, just my opinion, but I know I'll be buying more VPA heads in the future.
