Safe to use old lighter?

[stearns]

Hey,

I was at the flee market last weekend and found a really cool little lighter, picked it up for a euro hoping it would work. filled it up with vector and it lit like a champ (soft flame), and not only that but it lights every time i spark it, quite the novel idea.

on to my question. i have filled it, burned through the tank then re-filled it. at this point would the lighter be imparting any flavor on a cigar? it burns perfect, and would love to keep this little guy as a backup, or to use if i ever feel like using a soft flame. here are some pics for fun, i could only imagine what its seen




thanks for the help, happy smoking
