I recently got yet another Zippo to add to my collection (bringing the grand total up to a whopping 2) but I also did a little modding to it as far as the case coloring went. It started life as a weird jester card style lighter, so I threw it on a bench grinder. I ended up roughing up the brass underneath the paint as I was taking the paint off but I like how it ended up. It sits well with my other Zippo that I think looks awesome. Seriously, my brass Zippo is the bee's knees.
that I don't carry either of these daily, the brass one has a regular Zippo insert but the silver and gold one has a 4GB USB drive in it (from a previous post).
