'Bifaced', perhaps? Certainly, 'biface', meaning an ancient flint tool flaked into shape on two sides, is listed in The Oxford English Dictionary. So, such an implement, anything created by it or indeed anything else with two faces - such as a street clock, say - might be described as 'bifaced'.
you can tell there is at least 2 women in here (WeeKaz and Louisecheese) in 'aloof' and in 'cab' I dont see every letter from A-F in it - explain your answers LADIES!!??
I know there's an extra "o" but I reckoned that the word "atof" would be too obtuse. If you want an explanation go to http://www.mkssoftware.com/docs/man3/atof.3.asp
and be bamboozled. Mind you I always wondered where that word came from
