The Numyth fire piston: http://goinggear.com/numyth-vulcan-fire-piston.html I picked this up at a great price from the website linked above. Right out of the package I could tell this thing was built to last a nuclear freaking explosion. It's very similar to a mini-Mag Light, if you've ever held one you will know what I mean. It's very light, made from aluminum, and weighs in at less than 2 oz. The top end opens to reveal a hidden chamber, complete with a rubber 'O' ring to seal it tight, and can hold an ample amount of char material or extra rubber rings. The Numyth fire piston comes with extra rubber rings, and is very well made. A small, plastic container with lube is also provided for the compression rings, and it all comes in a handy plastic bag which seals for expedient use. It only took me the first try to get a glowing ember with this piston, too. You can open the opposite end to replace the piston for storage, and to clean if necessary. Yeah, it has quickly become my favorite tool. For the price ($40), it's a very solid buy. The price has gone up $5 already. Compare this to the highly priced, wooden type fire pistons, and it's a "no-brainer". Very high quality fire piston, folks.
