This electric internet lark is really the dog's wedding

tackle

I have half a dozen sets of Allen keys which are neither use nor ornament because the only one I ever use is the 5mm key and I have lost all of them and if I buy another set the weight will cause the old homestead to slide into the street. And if I did go to the local hardware store the bloke behind the counter would say nah mate, we don't sell them, there is one missing and promptly piddle himself laughing.
