I've seen these, and I think that Dave Cantaberry sells these on his website. They are supposed to be smokeless and odorless and quick and reliable. Mainly for military folks to be unnoticed with smoke/smell. Would be good on camping trips I would assume if thats what your wanting to use it for.
the only prob is thats not really cost effective for 1 or maybe a few fires, I know something light, simple to use, reliable. a magnifying glass of course it will only work on a sunny day but any type of fire stater will run out. this will work for years and 90% of the time this works all the time you can also look into transport fire in a box basically low burning wood charcol its a SAS special forces trick. the rest or the time I guess a woodbow we all need to learn that one regardless takes time but will work sunshine or not
Steel wool and a battery. Just loosen up the steel wool and rub the positive post of a battery over it. You have a nice fire starter.
Dried tree sap works good too. It is like starting a fire with gasoline.
I have always been a big fan of cotton balls soaked in vasoline. They just kind of work. I have also been impressed by igniter packets for wood stoves and also 'fire ribbon' which can start wet wood on fire easily, it contains thermite and even takes a spark.
