This one either makes perfect sense or is a bit over the top for you. For us, we view it as we're often times out on the trail, perhaps chasing that snowstorm for photography and filmmaking, and or out and about day-to-day. It's a small tool that can come in handy during an emergency situation.
So how does it work, easy:
The bottom side is a razor cutter for the seatbelt
The top is a hammer to smash your window open should you be trapped
Not a necessity, but certainly an emergency item that could come in handy in a precarious situation. Not to be an alarmist, but just a suggestion.
With spring almost here, we're excited to be outside in warmer weather. We hope you are too. Happy hiking (and adventuring)!
