The most manly shave I could think of is being shaved with a pink Bic disposable wielded by Raquel Welch when she was around 30 years old. :D
Otherwise I'd just step off my motorcycle while traveling at aprox. 160 mph and let the asphalt grind my beard off... only trick is to find a good aftershave that can calm down any potential razor burn.
