I bought a 6 pack, and tried them this season. I had a hard time at first, I ruined the first one. I decided to stick them in the kme knife sharpener, and after some work, they are the scariest sharp heads I have used. I finished them on a green strop from the knife company, and they went over the top sharp. I could easily shave with them. The one I sent through my buck this year just got stropped and is back in the quiver. I`m pretty impressed, been shooting snuffers and stingers for a long time, I`ll be using the grizzz for a while.
