I'd been looking for a waterproof fire starter. While I already had a butane lighter, but needed something while boating. The Blastmatch was attractive for a couple reasons. First, it contained the flint inside a plastic housing that was integrated with the striker. Second, you use a single hand to ignite your tinder. This is nice, because if you have to shield your tinder from the wind, or you need to hold a bear at bay while you light a signal fire...you know, your average outing.
While I didn't make the below video, it demostrates the product very well. I'd recommend it.
