I have a friend who is always complaining how tough it is too shave. He is part grizzly bear. His beard is very heavy. He has tried a Gillette Fat Boy and said he was not impressed, not sure how much effort he really put into it either. From my very limited knowledge I though he needed an open comb style. He complained the fat boy clogged up very quickly and he had to use extreamly short strokes. I also thought a Merkur slant might work for him, but he is not an experienced DE shaver. Any suggestions other then lazer hair removal.
