Simple and to the point.. I lost my paper that came with the heads and I'm wondering how to change the blades? thanks.

I threw mine away also but I did read the instructions and changed blades last year. I'm working from memory here. I took a small block of wood like a 2x4 and drilled a 1/4 inch hole in it. With the O ring in place ( blades closed) place the point of the broadhead in the hole and apply downward pressure and they should slide back and expose the keeper ring and slide off. Replace the old blades with the new ones and reassemble. Hope this helps. If not you could always go to Wal-Mart and read the instructions on a new package...lol.......Happy Huntin.........
