This is a silver metal lighter which is designed to work like a box of matches.

There are 2 parts to it:

1. The rectangular box part that you strike the match on and that contains the lighter fluid.
 
2. The match part is a metal strike device which creates a spark and ignites a wick on the end of the match.

The match part screws into the box part for easy storage and so that the wick is soaked with lighter fluid so it lights every time.

Its refillable with ordinary lighter fluid and can be lit over 15000 times.  You strike the match on the side of the box part. How clever is that!
