This multi-tool could save your life.
If you ever get lost and need to build a survival structure, you'll want this tool ($50) in your backpack. The nearly foot-long stainless steel blade is engineered to cut, carve, hack, and scrape available materials into a viable refuge. Paracord on the handle can also be used to lash the Jack onto a stick, turning it into an axe.
