The Shibata san Koutetsu R2 Ko-Bunka is a surgical tool that's made for the kitchen. With its incredible light weight and amazing edge retention, nothing quite feels the same.
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.

"Very happy. Feel, sharpness, edge retention, handle quality, blade finish. Genuinely a 10/10 additional to my professional kit, being used almost daily for fine cuts and gentle work."
"Excellent! Light, nimble, factory razor sharp, precise tip, hollow grind, quality experience."
"Incredibly sharp, beautiful finish, comfortable to use for long periods. Very happy with purchase."
"Don’t be fooled by its size. This little knife is a beast! By far the best for fine brunoise and other techniques that require accuracy on small ingredients. I’ve tried many different styles and makers and this line of knives is one of the best performing of them all, I highly recommend!"
"I was looking for something to handle lots of small jobs in the kitchen. I have a really nice Petty that is just about the same length, but found myself wanting a taller blade, but still a similar length. I did some digging around and figured this ko-bunka was what I was missing. It's been great so far! Love the weight and feel (which is rather light and nimble)."
"Very sharp, light weight and nimble. Fit and finish are top of the line."
"This is my first Shibata knife and won't be the last. The size is great when I need to cut protein on the dining table. Love it's sharpness and thin profile."
"The knife is thin! And awesome."
"Got this as a gift for my husband's birthday a couple weeks ago, and he's used it every day since. Great size, handles well, very sharp, and very versatile."
"Beautiful, simple and nimble blade. It came extremely sharp. Even though small, I bet I can do just about anything with this little knife."
