While credit-card sized multi-tools are commonplace to the point of often relegating themselves to dollar bins or As-Seen-On-TV promotions today, decades ago Snow Peak's Survival Tools offered high quality functionality in a relatively new package.
A pair of sharp blades combined with a multitude of functions allowed for the patenting of this piece, firmly establishing it as a unique part of a camp kit. The larger of two models, the rectangular shape still fit in to a pants pocket or attached to a belt using the included sheath.
Snow Peak continues to offer multi-function pieces to this day.
