This knife is the result of an exclusive collaboration between JCK and the Takeshi Saji Team — a prestigious forge-smith and blade-making family spanning five generations, now led by third-generation master Takeshi Saji, fourth-generation Kazuo Nomura, and fifth-generation Naoya Saji, Kenta Nomura and several of Takeshi Saji’s passionate apprentices.

With many decades of experience forging custom handmade hunting knives with traditional forged blades, the Takeshi Saji team has developed exceptional skills in custom handle-making and the ability to craft knives tailored to each customer's specific needs. These techniques, honed through generations of knife-making, now define the characteristics and quality of Takeshi Saji's custom kitchen knives.

Together with JCK, we created something you won't find anywhere else: a Bunka with an innovative upswept blade profile that works beautifully with any grip style, while being especially optimized for pinch grip users who will appreciate how naturally and effortlessly it cuts.

Designed for How You Cook

Every detail serves a purpose. The upswept blade creates forward motion. The slanted bolster improves balance. The contoured Forging Red Color Linen Micarta handle fits your hand perfectly. This isn't just beautiful — it's a tool built to work as hard as you do.

We chose R-2 Powdered High Speed Tool Steel for its exceptional edge retention and performance in professional kitchens. Master Saji's unique "Diamond Damascus" forging creates a sparkling pattern that catches the light — beauty that inspires even in the busiest kitchen.

The Bunka is a general-purpose kitchen knife that used to be just as popular as the Santoku, but has become less commonplace in recent years. With its tall blade, the Bunka knife is particularly suitable for cutting vegetables or fruit and the triangular tip area is particularly useful for detailed work and cutting fish or meat.

This knife comes with 50/50 double bevel edge geometry for both right and left handed use.

For your information, Japanese Kitchen knives are generally designed for right hand use with a slightly thicker and rounded grinding on the right side blade and a less rounded (almost straight flat) grinding on the left side blade. However, both right and left hander can use the knives that have double bevel edge sharpened 50/50 without problems. 

We believe the quality and cutting performance of Japanese knives are the best in the world, and hope you enjoy fine craftsmanship and sharp edge with your new knife. With proper cares, every Japanese knife should be your special cooking partner for long times.
