Butchers Danger Wank 

The act of self pleasure where one (usually a butcher) takes a freshly sharpened knife and places it underneath his scrotum whilst masturbating. Knowing that any slip or excessive movements will cause severe damage adds to his depraved sense of excitement.

Mum warned me not to use her good steak knives if I was to have a cheeky Butchers Danger Wank.
