Another of my favorites is the nanoSTRIKER XL also made by Exotac Inc. Ferrocerium's main weakness is salt from sweat or salt water. The nanoSTRIKERs are a sealed unit that store the rod in the handle and have their own striker. On these the rod is threaded and replaceable so when you wear it down you just replace the rod not the whole unit. I have a few of them, and a smaller Ti model that has been on my key ring for nearly four years that I am never without.
