Those with a coarse beard need to learn how to hone their own razors. That is the only way to produce edges that are optimized for your beard. Even that can be hit or miss. I have produced edges that seemed to be "shave ready" based on the usual predictive tests, but yet they failed the all-important shave test. In that case, they go back to the stones or the pasted strops based on what the edge seems to need. Because razors vary is type of steel, tempering process, and grind, not every razor responds the same way on the hones and strops. That is why I have a collection of stones and strops.
