hello,
I thought this maybe of interest to NBCUK forum members. I received through a rep from http://www.thatcompanycalledif.com some plastic credit card sized "Magnif-i" lens (4 pack) which may have a possible use for fire lighting. I've been informed rrp. £1.99p. I've been successful in the past *pending the Scottish weather, creating a fire using a magnifying glass along with a similar plastic credit card sized sheet I picked up at the optician's for free. These "Magnif-i" cards measure 85mm x 54mm made from solid rigid 'fresnel' lens come in a PVC sleeve. The cards themselves have a built in clip along the top used as a page mark or could be useful to affix a lanyard? ideal item the "Magnif-i" if proven to work as a method of fire starting for the EDC kit or FSK tin/pouch. A number of Bushcrafters State side have used similar with effect, after all they have the glorious sunshine unlike here in the UK. *Image 2 similar sized same spec credit card sized fresnel lens.
