On your hawk from Crazy Crow, I would only put a few tacks on it if you are going to try thowing it, otherwise you will "unbalance" it, if you add much more. If you are going to just use it for chopping, you can add tacks, rawhide on the handle, and maybe a "drop" like I put on mine. The Pipehawk you can put whatever you want on it cause it is more for looking at, than for using.
