HPE is built upon the design principle of multifunctionality. Knives and blades have traditionally been one-trick-ponies when it comes to outdoor sports, and thus have been relegated to a paper-thin blades on multi-tools, or not carried at all.
I believe that a tough, re-sharpenable, full handled knife is essential for both emergency use and for quality of life in the backcountry.
All HPE knives will serve you not only as a blade, but will also incorporate useful and creative solutions for outdoor tasks. Never again will you curse the grams you allocated for a knife that lives its life tucked away in the brain of your pack.
