Hammer would be Scumble, from Discworld (He actually carries a severely distilled deadly kind of Applejack in a flask with him, that is pretty much this!)
Quote:From Mort
"A lot of stories are told about scumble, and how it is made out on the damp marshes, according to ancient recipes passed down rather unsteadily from father to son. It's not true about the rats, or the snakes' heads, or the lead shot. The one about the dead sheep is a complete fabrication. We can lay to rest all the variants of the one about the trouser button. But the one about not letting it come into contact with metal is absolutely true..."
