Query: Good until broke

With a little practice you can very quickly start a fire with less hassle then plain fire steel. You don't actually need a giant pile of shavings to start a fire if you have gathered the correct kind of tinder. Enough shavings to cover a dime would be sufficient to get a moderately dry tinder ball to start going.There are cons to this product though. I have owned 3 of these, and of those three 2 had the fire steel come lose from the magnesium brick (the other was lost in a lake). Yes you can just glue it back on, or keep it lose, but that's not the type of reliability that I'm looking for in this type of tool (obviously this is for survival situations, or you would have matches or a lighter). I much prefer just a plain old fire steel with striker for reliability sake.A side note is that the fire steel will burn the finish of your knife, so I suggest getting one with a striker for practicing.
