I like them, never had entrance holes like this before. I had to slightly straighten one blade,then sharpen all 3 and I was good to go. Use the search function and you will find tons of info on them.
I have never had one open in flight...just when something brushes against them. Hovever, because of that I would not want to shoot one through some leaves or grass at an animal...If they are opening that easy do they open in flight or have you not had this problem?
You do know you caould have sold or maybe even returned them to the store???i shot the 3 blade for the first time last week and it opened almost as soon as the arrow left the string. i threw the all three of them away if it came open in flight once i dont want to take anychances of it happening when im shooting at an animal
