We're planning a trip to Hunan province in China next year, and I was wondering about getting a hone and a couple of razors.

When I was there previously, I'd noticed barbers shaving people on the street. I thought I might buy two new razors if possible, one for the barber to shave me with right then and there and another to take home and play with. Anything I should know about buying razors in China? What should I look for? What should I avoid?

The other thing I'm considering is a hone. I've heard about the stones from Guangxi province. How do I go about choosing a good one for finishing? Again, what should I look for and what should I avoid?

Thanks.
