Striker only!

If you are happy to find your own flint & make your own char-cloth

You can grab yourself this superb quality striker for a steel (pun intended)

Many other minerals will also serve as your "flint". Agate, carnelian, jade, bloodstone, chalcedony, quartz, and chert all work well. Any hard stone, which fractures to a sharp edge, will do the job.
