Raspy, flint was the very reason I went to electronic lighters. I have had, over the years, several flint lighters where the flint degraded so badly that it actually turned to powder. I guess there are good and bad in all butanes. Just a matter of finding the right combination. But, based on all past experiences, from now on I am going with electronic Crickets. I have not had one to fail yet. Only thing I don't like about Crickets is that some of them do not have a flame adjustment lever on them.
