Nothing is as good as those dang pros...they have me beat in most things as wellWhen available, I used deer antlers. Most of these I did with a piece of 1/2" copper tubing with the end hammered flat.
Nah, they are in a container in a cupboard and very rarely see the light of day. They are pretty poor quality when you see what the pros can create.

But they (your arrowheads) certainly seem pretty cool to the average amateur like me!
