Yes, amadou as Tone has noted. With regrets, I am not very familiar with the woodland flora of the UK, however experimentation is half the fun. On this side of the pond I have used the piston to iginite the following; True tinder fungus ( Innonotus Obliquus ). False tinder fungus (Fomes Fomentarius ), Milkweed pod, Pith of the Mullein stalk and plain, old rotten wood punk. Punk may require two or three hits to ignite - but what tinder is more plentiful in a woodland environment...
