Making magic items to show as not identified.

Hi I'm probably missing something bloody obvious, however...

I want to create a magic item for my campaign, and make it unidentified. However, when I look at tutorials it shows there's a function for that, but I cannot seem to locate it. The tutorials used 4E while I'm using PFRPG, not sure if that might be the issue, but any help would be appreciated.

I believe there's an option you have to turn on, and then mark it as unidentified. Although if you have crafty players they can figure out what it is based on the to hit and damage rolls.

Options -> Identification -> ON.

Thank you both :D
