We always took flashlights, and made sure the batteries were good, and probably had extra along, just in case. Usually, we didn't have to use it a lot at night, but it was good to have it when we did need one. It was one of those big spotlight ones that would shine quite a ways, so we could shine it out into the woods if we heard an animal moving around out there, or just needed to walk out into the woods to go to the bathroom. I now have one of those radios that work on either batteries or a hand crank, and if I went camping , I would certainly take that along. Also, my iPhone has a flashlight accessory, so when I just needed a little light for something, then that would work fine.
As was mentioned, the crank radio/flashlights need a lot of cranking for not much playing time; so having good batteries in them is definitely the best plan, and use the crank when necessary.
We didn't have any of the fancy knives with all of the blades; but my dad and grandpa always had their pocket knives along, and they were kept sharp. We also had a good hatchet, hand saw, or even the axe along in case we had a big tree limb across the road, and had to cut it in order to get through and out to the lake.
