I was playing with this in the early nineties, don't try to create a light from one single strike. Your better bet is to slowly grind filings of the flint from the lighter so they fall in your tinder (time consuming) and then give it a decent grind to ignite the filings from the flint.
Whichever tinder you use make sure it is reasonably fine, lite, dry and you will be able to get it to go, I have managed to get 000 grade wirewool to light from it in Cyprus, but it will take a lot of work to get there.
