I got all of this together, there is the fire piston itself plus a lot of other bits. These are
A small tin containing some charcotton wool (I think), 2 types of suitable fungus, a couple of spare "o" rings, lubricating grease, and a small brasss rod to freee thw ember once burning.
A tinder box, and some instructions.
I had real problems getting my first ember, to the point that I emailed the maker and asked if she had tested it before sending it to me. She had and it worked fine, there is just a knack to it
. I found it best to place the piston part on a solid surface and then align the other half and sharply smack it down on to the piston. It took a few days before I managed it though.
Let me know what you think.
Cheers
