DESCRIPTION
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.

FAQs
You've got four main series. What's the actual difference?
Supreme (The Workhorse): Your durable, reliable first great knife.
Retro (The Upgrade): A big step up. Stays seriously sharp, for longer.
Mo (The Stunner): All the sharpness of the Upgrade, in a beautiful Damascus finish.
LAN (The Pro): Our absolute best. Elite steel for an edge that just doesn't quit.
Is the wavy 'Damascus' pattern on the Mo and LAN series real?
Oh, 100%. That’s not a cheap laser-etch you’ll see on knock-offs.
It’s the real, beautiful result of folding 67+ layers of steel over that high-performance core. It looks incredible, and it even helps food slide right off the blade. This is the real deal.
So... can I put my knife in the dishwasher?
That's the one hard "no." A dishwasher's high heat and harsh soap are brutal on a sharp blade and a beautiful handle.
The simple fix: Just give it a 10-second hand wash with warm, soapy water right after use. Done.
Aren't these just 'Made in China' knives?
Yep. They’re made in Yangjiang, the "Capital of Knives."
Here’s a fun fact: Yangjiang has been mastering this craft for over 1,400 years. That’s centuries before the famous hubs in Germany and Japan even got started.
So we take world-class steel, send it to the city with the longest history of making world-class blades, and skip the legacy-brand markups. It’s not just a good knife; it's a smart one.
What's the warranty? What if I don't like it?
Easy. If it's not love at first slice, send it back within 30 days for a full refund.
You're also covered by a lifetime warranty against manufacturing defects. And as a 100% Aussie company, you’re always protected by Australian Consumer Law. We’ve got your back.
