Be The Jam

Creates a spark that with a small amount of practice can be used to create a flame.

Absolutely brilliant, not just because it is hugely rewarding to light a fire without the use of lighter / matches / metal objects and a microwave but also because it is very very useful. It works in all conditions; wet, dry, windy, still, snow, hail, fog whatever. Far more reliable than any lighter could ever be.

Absolutely essential bit of kit

Good for impressing your mates with in the pub when someone asks for a light.

Never go anywhere without it
