The very light weight corrugated white cardboard that is used to surround light bulbs, as liners for cookies etc. burns very hot...Shredded light cardboard is far better then plain paper...Being more porous there is larger air pockets between the fibres causing a far more intense heat.
I always carry a couple small pieces of fat wood in my fire sack but only use a small piece of it to get a wet fire going...There is a small bag of it in the trunk of all the family's vehicles.
There is a toothpaste styled tube, called "Fire Ribbon" that when squeezed onto a log and ignited burns intensely and is nice since it's sticky you can put it directly on the bottom side on a log.
I carry upon my person and within my pack: a Blast Match, a Strike Force (both by Gerber) with the Wet-Fire tinder packs, flint and steel with char cloth stuffed in a brass case with a magnifying glass in the lid, a magnesium fire starter, wind/water proof matches, Strike Any-Where matches, a Zippo lighter (and fuel),
a high tech piezo super duper [refillable] butane lighter and a few disposable, piezo and/or regular, butane lighters as well.
There is fat wood, shredded cardboard, dryer lint, Vaseline cotton balls, tube of Vaseline, shaved fuzz sticks, fire ribbon, char cloth and frayed sisal rope in freezer bags for storage...They are ONLY used to start fires during inclement weather...Regular day, shore lunch is some birch bark, some twigs and some larger stuff started with a lighter--save the high prep stuff for high stress fire making...Know how to use the stuff but save it for when you need it.
Ultimate Survival -- who made the sparkers for Gerber -- also came out with a new device called "The Sparkie"...2.3" x 2" x .05" long, weighs 0.08 oz., in sand or orange and has a lanyard hole so you can carry it on your keychain (which I do)...$11.00 on sale, regular street price about $14.00...They work!
There is also some chemical starters...The one I had consisted of two squeeze bottles each with a different, volatile, ingredient within...You "spritzed" some of bottle A on the tinder and then some from bottle B and voila, it exploded into flame...You also had to do it in A then B or it didn't work...The instructions said you had to store then apart--duh, obviously but what they didn't tell you is that the liquids are somewhat corrosive, eat through plastic bread wrappers quite easily (and quickly) and the chemical company never replaced the Kelty Framed backpack that exploded into flame, whilst I was wearing it mind you...I was able to remove the pack but the contents (five days of food and clothing etc. of a seven day backpack trip) were totally destroyed--the metal frame--in a few spots, even melted into a puddle of aluminium "nothingness" due to the fire's intensity...I'd really like to find that type of accelerant again but since that
"dweeboid" got some onto the aeroplane you can't find it anywhere (places that I'm looking in) and the "NEW" stuff is supposed to be more stable and you actually have to mix then together before applying the paste that, after agitation, it turns into.
