When I assemble my Hill single bevel broadheads, I need to hammer in the rivet. I drop about one out of three. Over the years I have dropped about 20 of the little buggers and have yet to find one back. I am pretty sure that they are all in rivet heaven. When I shoot a Schulz Hunter's Head tipped arrow, whether I hit or miss, that arrow goes to first time shot arrow heaven. The one that really bites my butt is the first shot I made last year with a judo tipped tapered cedar in a disced bean field, about 30 yards, and gone in broad daylight. However, when I was tracking my wifes deer I found three arrows shot a long time back by other hunters on my way to the deer. Go figure, I can find other peoples arrows by accident, but mine completely disappear.
