How it's used
Refers to a large, long-bladed knife that is often associated with street violence in Hong Kong crime films. While it is technically a kitchen tool for cutting large melons, the term carries a strong connotation of danger and triad activity. Using it in casual conversation can sound quite dramatic or aggressive.

Common mistake
Do not use this term to describe a standard kitchen knife, as it specifically refers to a very long and intimidating blade. Using it for a small paring knife will sound confusing or unintentionally funny.
