The Bunka (文化) is a versatile general-purpose Japanese knife and a common variation of the widely popular Santoku knife. It is adept at cutting, chopping, slicing, dicing and mincing foods such as meat, fish, vegetables and herbs.

A Bunka knife has a reverse Tanto angled tip, also known as a K-tip, that allows for more precision and accuracy when needed. Depending on the culture, the term Bunka is sometimes used interchangeably with Santoku.
