You know I shot muzzy's and thunderheads for over 2 decades. I loved the price. They were always razor sharp. But I hated that out of a box of 6, I might get 4 that spun perfectly. Hated that the they were so easy to damage. last straw was the blades would come off easily after hitting bone, and I was butchering a deer and found one of those blades in my hand. I switched to slicktricks.
