Im sensing that the Croatian made Katana is probably one of the rarest mods known to the vaping world. So of course I set out on a path to locate one of these, knowing the final outcome!! What I am understanding from the maker is, he only made 30 of these units and no more. Im sure they were gone before they ever even started. There is a youtube video of the maker known as peaceoffcake, and these mods are to die for. So I thought hey what the heck i want one. Yea right!! Can anyone who does own one of these give me a little info on how they are built and how they vape I would love to know. Thanks, Flynn
