My dad is extremely difficult to buy presents for, you spend hours trekking round shops wracking your brains, and even when he gets them tends to be inscrutable and so you're never quite sure whether he really likes what you've bought or not. In general, therefore birthday present buying is approached with some trepidation. This year I bought him this swiss army knife, knowing that he had a much more basic one and found it useful. I was not disappointed, he actually appeared very pleased, and spent a lot of time investigating the uses of all the attachments (which there appear to be a couple of hundred of). I can highly recommend it for any man who loves a gadget, and as it comes inside a box, it's even easy to wrap up!
