Foodblogger Cha Xiu Bao has great photo set of the noodle-making process at a Hong Kong noodle shop. Complete with a knife that would make Crocodile Dundee proud.
The cleaver held by master Shiu weighs in at 2 catties and 12 taels (1.6kg in plain English). Each day, he hand-cuts each one of the hair-thin gold noodles with this massive blade of his. The broth for the noodles is made of chicken and Yunnan ham, and is double-boiled for over 12 hours. Believe it or not, the noodles sell sinfully cheap at just HK$28 [US$3.60] a bowl.
1.6 kilograms in plain "American" is roughly 3.5 pounds!
