not quite sure, I think it is its own company. go to google and type in "slick trick broadheads" The fist hit that comes up is a review from huntinfo.com. The third hit is slicktrick.net, thats where you can order them. The days of tuning in broadheads and getting flyers are OVER! you screw them on and go. Let me know if you need anything else. Bill Bell Thunderhead is also a good head, but they do require tuning for sure.
