Like I said, I brought one home from my first trip to China too. They actually make those in the same dimensions but different weights. Thin ones for slicing meat and heavy ones for chopping through bones. You can't tell the difference without picking them up and looking at the spine thickness.Ha! Err... yes... I mostly bought it cos it looks cool.
Having said that - whenever I buy a new cleaver my wife's response goes along the lines of: 'Can I use it to go through bones? If not then it's not a real cleaver is it.' So hopefully it'll keep her happy. And her father is a cattle farmer and we often have cows (or parts thereof) in the freezer, so it might get to see some real work too.
(Not that I'd have the faintest idea about how to butcher a cow!)
