You CAN get a knife arm hair shaving sharp with a 325 grit diamond stone easily. It depends on the technique. Fact. Flower the pressure in the end and use alternate strokes.
PS: do not be afraid to use "coarse" stones, they are way more important than finer stones because with them you create the clean geometry. Refinement takes much less time. Once you achieve a clean new bevel geometry you can use touch ups, but don't over do it.
