As one of the most desired "holy grail" materials in the EDC world, Titanium is worth its weight and is a fantastic metal to add to your EDC collection. Titanium weighs almost the same as aluminum but is stronger than steel. Its high density and hard oxide layer makes it highly resistant to corrosion even in sea water, aqua regia and chlorine. It is non-toxic, non-allergenic and perfectly compatible with the human body. It is even more durable than gold and has become a popular choice for designer jewelry.
