These Hammock Anchors are the Titanium DIY version of completed Tarp Anchor. They have been cut from a sheet of titanium. However, they need the edges chamfored and deburred. You have the option to use a piece of scotch brite to polish if you like. No need for complicated tools as Titanium is not as hard to work with as most people think. A file some and some 240 grit sand paper will get the job done. If you have a dremel tool that will make quick work of the job aslo.
