As we learned, the word bunka means 'culture', and ko means 'small'. So you guessed it, the ko-bunka is basically just a smaller version of the bunka! It sports the recognizable reverse tanto tip, with a blade size that is scaled down a bit. Why not just call it a petty then? While the dimensions definitely put it in that ballpark, it has an extra dimension of functionality due to its blade height, as it keeps the proportions of a bunka. This means enough knuckle clearance for comfortably chopping herbs, mincing garlic, prepping veggies or even cutting meat. And it looks cool!
