Bests & Worsts Reviews from Amazon

This is one of the best fire starters you can carry. Another reviewer indicated it wasn't much good unless you have a sharp knife. Not only is a sharp knife not required, it's a very bad idea to use one. Shaving the magnesium then scraping the metal match insert with your knife will certainly work, but it will also dull your knife in short order. It is a much better idea to attach a piece of a hacksaw blade to it for this purpose. It works as well and lets you save your knife for its intended purpose - cutting. Even if you have no or hacksaw blade (or knife), a sharp piece of broken glass will let you shower sparks from the insert. That alone will get your fire started (though if your tinder is damp it's easier when you can also use magnesium scrapings). A cotton ball smeared with petroleum jelly makes excellent tinder to use with this device. A dry cotton ball also works; it just doesn't burn as long. Put several into an old film container then drop in it your pack with the magnesium fire starter. The bottom line is this tool is small, light weight, inexpensive, reliable and easy to use. These attributes make it an excellent tool and an outstanding value.
