The Light My Fire Spork Titanium is made of titanium, one of the toughest alloys on the planet. Titanium is widely used in aircraft construction because of its lightness and extreme strength, yet it is also used in surgical and dental implants. Its high biocompatibility means that it is very non-toxic and is not rejected by the body. Great for your next outing, no matter where it is. Same design as the Spork original.
