About the Shape -The Ko Bunka is a smaller version of a Bunka. Any guesses on what “Ko” means in Japanese? You nailed it! It translates to “small.” This little knife is awesome because it still gives you knuckle clearance on the cutting board. Making sure you can mince garlic and comfortably chop veggies. A badass love child of the Bunka and Petty knife, it works for smaller jobs in the hand or as an all-purpose blade.

About Masashi Shiroshu - Masashi-san makes a beautifully polished and crazy sharp blade, working entirely by himself hand-forging, sharpening, and putting on the handles. He’s also a bit of a risk taker, forging knives in his flip-flops and lighting cigarettes off white-hot knife steel. Bad. Ass. This shiny, sexy damascus blade combines extreme good-looks with ruggedness and ease of maintenance. SLD stainless steel gets razor sharp, but doesn't rust like carbon steel.
