You can get them here but it is a trip right. You can't just get one from Wellcome! I had mine sent from the UK and didn't see one in HK for over a year until I saw one in a little boutique in Sai Kung. As I said to the OP, he'll have enough on his plate without faffinf about looking for things like that!
When in doubt, try Ikea, they have pretty much most things in the way of kitchen utensils.
They didn't have one when I was looking, nor did Park N' Shop or Taste, same goes for bread knives. You guys would have laughed, my wife thought I was going nuts, I even looked potato mashers up on Alibaba, contacted a supplier in Hong Kong and toyed with the idea of buying the minimum order of 500 before I snapped out of it and had one sent over from England![]()
