Nest of Wipers

As the annual brainstorming session at Gilette draws, yet again, to an inconclusively close. Some bright spark breaks the suffocating silence by once again piping up to say 'well we could always put another blade on it. Then market it by suggesting that if you use it you will be as cool as a fighter pilot whose girlfriend always sneaks up behind him whilst he's shaving for the sole purpose of caressing the end result.'
Smiles all round. The relief is palpable. Well if it works for razors why not for windscreen wipers. You could even have a second, harder blade that could be lowered for bug removal.
