This utility ring is made from aerospace grade titanium and will make sure you’re prepared in every situation. It has five different tools including a bottle opener, a straight blade, a serrated blade, a saw, and even a comb. Okay, it’s a teeny tiny comb but it does the job (on mustaches maybe). It measures 9mm wide and is custom made to your size for a perfect fit. Just think how handy this little ring could be during the zombie apocalypse.
