If you should be out camping, you might want to start a little fire at some point to make a meal, or just use it for light. It’s always nice to have a campfire to warm yourself by at the end of a long day, but starting a fire in the middle of the wilderness can be a bit difficult if you aren’t well-equipped. Not many people prefer to be in the dark when outside at night, but without the necessary tools, there’s not much you can do.

The nanoSTRIKER has just about everything you’ll need to start up a fire, and is disguised as a keychain. It weighs only 0.6 ounces, and is less than four inches long. Unscrewing it at the halfway point, you can remove the Magnesium rod and screw it onto the handle. The other portion of this little tool is a ferrocium rod, which will spark and ignite once struck against the other rod. This whole package is yours for about $24, and may just be of use should you be out in the wilds.
