A cutting comb should be used just as you would use a straight razor to do a razor cut.
Never just run the cutting comb through the hair. Use the comb as if you were using scissors, only on the ends of the hair where you want the hair length to be. They are used to give the ends of the hair a more feathery look instead of a blunt cut look.
Suggest you get some one who has experience in cutting comb and razor cuts to show you the proper way to use the comb. It is very difficult to explain how to use them. Better to be shown proper use.
