Zwilling Four Star 6.5-Inch Bunka Knife

A precision prep knife designed for fast, controlled cutting with exceptional tip accuracy.

The Zwilling Four Star 6.5" Bunka is a hybrid prep knife that combines a Japanese-inspired profile with Zwilling’s German-forged durability. It’s designed to handle everyday cutting tasks with speed on the board and precision where it matters most.

The defining feature of the bunka is its angled “K-tip” (also called a clipped point). This sharply defined tip gives you far greater control for detailed work like scoring proteins, making horizontal cuts in onions, trimming, and handling fine garnishes.

At the same time, the flatter edge profile allows more of the blade to stay in contact with the board during each cut. This makes it highly efficient for chopping and slicing, especially when working with vegetables or performing repetitive prep tasks.

Unlike knives with rounded or squared-off tips, this combination of a flat cutting edge and a precision tip gives you the ability to handle both high-speed prep and intricate work with a single knife.

The taller blade provides knuckle clearance for comfortable board work and a wide surface for transferring ingredients directly from board to pan.

The 6.5" length keeps the knife compact and easy to control, making it well-suited for everyday prep, smaller cutting boards, and tighter workspaces where a larger chef’s knife may feel oversized.

Forged in Solingen, Germany using the SIGMAFORGE® process, the blade is crafted from a single piece of Zwilling’s proprietary 1.4116 (X50CrMoV15) stainless steel. The FRIODUR® ice-hardening process (57 HRC) improves edge retention and durability, helping the knife maintain sharpness through repeated use.

The full bolster provides balance and control, while the seamless Four Star handle is molded directly to the tang for comfort and hygiene. The result is a knife that feels stable, responsive, and easy to use across a wide range of prep tasks.
