How many times have you been surrounded by Daleks looking to "terminate" and in need of a handy tool to save your skin? Okay, so maybe that's not a daily occurrence for you like it is the good Doctor, but chances are that you still dream of wielding your very own Sonic Screwdriver. Now, you can! This 10th Doctor Who Sonic Screwdriver comes straight from the hands of the Time Lord to you. Although it doesn't quite have the functionality of the one used by David Tennant in the series, it DOES help you write cryptic messages using it's secret ink. That way, you can leave notes for your future incarnations without anyone else reading them while you wait for your new form to regenerate!
