I have not hunted with them, but I did do some testing with them in both the standard and Deep Six version. I decided not to use them, but some have had very good success on animals and some have not based on internet reports. They do fly well though. I liked the trocar tip and the fact that they use 7075 aluminum, which is almost as strong as steel. I don't like the fact that the tabs or fins of the blade that stick out prior to deployment, are actually blocking the cutting edge of the blade when deployed. It isn't much, but that bothered me. I also don't want a blade that "pivots" around bone. Also, the blade edge was not as sharp as I prefer. My favorite mech is the original Steelhead 125. I just picked up two more dozen from the original Rocket owner. Those things are almost indestructable and always work great. Good luck.
