8.5" Bunka Knife - Zhen Series (PM8M)

The Bunka is the ultimate fusion of agility and aggression. With its distinctive "K-Tip" (reverse tanto) profile, the Zhen Series 8.5" Bunka is designed for chefs who demand laser-like precision. It functions like a chef's knife for slicing but offers the intricate tip control of a much smaller blade.

Legendary Japanese Aogami #2 Steel

This is not an ordinary stainless knife; this is pure cutting performance. The core is forged from Japanese Blue Steel No. 2 (Aogami #2), a high-carbon steel revered by sushi masters for its ability to take a frighteningly sharp edge. Heat-treated to an ultra-hard 62–64 HRC using vacuum heating and deep freeze technology, this blade offers edge retention that standard kitchen knives simply cannot match. It is clad in softer stainless layers (San Mai construction) to protect the core, leaving only the cutting edge exposed.

Traditional Elegance

The handle is a work of art, crafted from blonde Maple Wood paired with a genuine White Buffalo Horn bolster. This traditional Japanese Wa-style handle is lightweight, balancing the knife perfectly forward to let the sharp edge do the work for you.

⚠ IMPORTANT: High Carbon Steel Care

This is a high-performance tool, not a low-maintenance one. The cutting core is non-stainless high-carbon steel.

• Rust Risk: It WILL rust if left wet, even for a few minutes. You must wipe it dry immediately after use.
• Patina: Over time, the edge will develop a blue/grey patina. This is natural and protects the steel.
• Acid Sensitivity: Reacts quickly to lemons, onions, and tomatoes.
• Purchase Warning: If you are not prepared to wash and dry this knife immediately after every use, please choose one of our stainless steel series instead.
