I remember those quivers, and I have the scare to prove it! Suicide quiver is an apt name.
When I was about 15, my first "hunting weight" recurve was a Bear '76er, ugly, red, white and blue, 50#. I wanted it to look more like a "real hunting bow" so I added camo socks, a "suicide" quiver, brush buttons... you get the picture.
I had the bow on a bow rack on the wall above my bed. I came in one day and "flopped" on my bed on my back, the bed hit the wall, and you guessed it , the bow, with quiver and bear razorheads came down, right on my left hand.
The broadhead cut my left thumb most of the way around and down to the bone.
I'm lucky the bow didn't fall on my neck or chest.
Yep, I was young and dumb, just never thought of the risk of having that bow above the bed, but in my defence, my room was a converted porch, one whole wall was windows, and the other sliding glass doors into the house, if I remember correctly, that was the only full wall I had in my room.
I am careful now sliding a broadhead tipped arrow into any bow or side quiver, I have a fear of the head coming through the hood!
