I've been trying to find a brass one...
I bought one of these last year and it is one of the most useless things I have ever spent cash on. On a good day it took 30+ attempts to get a flame. Most of the time it wouldn't produce a flame no matter how many attempts you made. I changed the flint in the hope that would help but it was the same. Ended up in the bin. Best avoided in my experience.true utility do one, available off amazon. Whether it is the best or not I dunno. Not really recommended in a high wind, but unlike a zippo, which needs constant refilling because of evaporation, the O ring does mean that it will fire up reliably even if it has not been filled in a while, that makes it useful to keep on a key ring.
