The keychain grenade is awesome. Great for camping,fishing,or just plain ole survival. You can never be sure these days,so I highly recommend this item.
It is very cool. I have it on my backpack in case i need to catch a fish in an emergency situation.
The perfect back up equipment for fishing if I don't bring my rod with me, when I go hiking in the mountains near a river, or walking along lakes. Clips on to anything, small size, and is very light weight, that is a plus for me since my backpack is usually full.
