i have a shaved head but i normally dont bic it.... i just use clippers with no attatchments so its super close.
this looks like a pretty cool tool for it. the type of razor makes a big difference when shaving your head...if you use a cheap one, for example, you will cut yourself a lot....which doesnt feel or look too cool
i might actually look into getting one of these bad boys
it says its only 15 bucks at walgreens or rite aid...not much more than my mach 3 turbo that i use now.
