i just picked up this one...

I have one, and it is extremely finiky... ive spent over an hour once trieng to get it to light

My piston is all modern, made of aluminum and with o-rings. Like Schwert, I use chaga tinder fungus. I'm planning on going camping end of February and will bring it to play with if I remember. I might bring the Himalayan Imports Sirupati that was given me too. Same guy that gave me the fire piston gave me two kuk's. Can you believe it? And all I did was help him out a tiny little bit.

i just got my piston in the mail and it lit up within 3 minutes of working. its fired up 8 or 9 times in the last 15 minutes, trying to get a decent picture.

i used char from jute twine. it even went up once on the first try. im so happy!...FIRE!

Now I am going to have to build one just to try it out.
