When you're camping, there are often times when you need an axe. But axes are bulky and don't always justify the extra weight in the pack.
The Klax Multi-tool is a nifty 7-in-1 tool that can transform into an axe if you need one. It's a handle-less axe (or tomahawk or hammer) that can quickly be strapped to a branch or separate handle to quickly transform into an axe.
The Klax is made by Klecker Knives, who make some high-quality and interesting survival equipment.
