Imagine a situation...when you are just about to light your boss's ciggeret and suddenly you realize that there's no gas and he's waiting with the ciggie between your lips and you ticking off with that empty thing. What an embarrassment!

To save you from that, here is a unique lighter design that uses no fuel no gas but the good old concept of rubbing flint and file to produce fire.
With this interesting design, you just have to turn that flintlock and there goes that spark...with no more embarrassments.
