I had a rather enlightening moment this weekend when out camping. I used a marlinspike hitch and a tent peg to hang my daughters hammock. It's one of the Parrot Bay hammocks. I left the little S hook on the loop, and ran it over the marlinspike hitch. The tent peg was a el cheapo spike style as you can see in the picture. I am just explaining this so that you can understand what you are seeing in the picture.
Here's the warning. Be careful when using this as a suspension as you could easily lose an eye. I was wandering around the campsite, and while I didn't lose or poke anything, came dangerously close one time to finding my eyeball impaled on the end of this spike. It was one of those "Holy Cow" moments when I realized I had just missed disaster. If you are going to use a stick or tent peg, or any kind of spike to hold your marlinspike hitch, be very careful. Would hate to see someone or someone's child lose an eye.
