How do you make fire in the woods? Without matches or nifty little gas powered wands?

I'll have to take/post some pics, but I have a Swedish Fire Steel that a Swedish friend actually made and sent. The handle is a cool piece of antler. Striker is the universal: hacksaw blade. Have another ferro rod that a knifemaking friend made. One thing that interests me are fire pistons. Anyone else have any firemaking goods? What do you use?
