Nobody hands you a rulebook when you start in a professional Japanese kitchen. The etiquette around knives is not written down anywhere. It is observed, absorbed, and expected — and breaking it marks you immediately as someone who does not understand what they are working with.
One of the first things an experienced chef told me when I started was this: own your own knives. Do not rely on the restaurant, do not borrow from the kitchen, do not expect your employer to provide what you need to do your job properly. Your knives are yours. They are your tools, your responsibility, your professional identity.
That single lesson contains the entire philosophy of Japanese knife etiquette. Here are the unwritten rules that follow from it.
The Rules — What Every Professional Knows
Rule 01
Own Your Own Knives
A professional chef carries their own knives. Not the restaurant's knives, not borrowed knives — their own. This is non-negotiable in serious kitchens. Your knife roll is your professional kit. It goes with you when you start a new job, it reflects how seriously you take your work, and it is maintained to your standard. A chef who relies on house knives is telling everyone around them something about how they approach their craft.
Rule 02
Never Touch Another Chef's Knife Without Permission
This is perhaps the most fundamental rule and the most universally observed. A chef's knife is personal in a way that very few objects are. It has been sharpened to a specific angle, balanced to a specific feel, and maintained to a specific standard. Picking up someone else's knife without asking — even just to look at it — is a serious breach. In some kitchens it is the kind of thing that creates lasting tension. Always ask. Always.
Rule 03
Keep It Sharp — Always
A dull knife in a professional kitchen is not just inefficient — it is unprofessional. The expectation is that every chef arrives with their knives in working condition. Sharpening is not something you do when you notice the knife struggling. It is something you do consistently, before the knife needs it. Sharpen little and often — never wait until the edge has visibly deteriorated. A chef who works with a dull knife is working below their capability and below the standard of the kitchen.
Rule 04
Care for It Like It Matters
Hand wash after every use. Dry immediately. Store properly with a cover or sheath. Never in a shared drawer, never left wet, never thrown loosely into a bag. The care routine is not optional and it is not something you do when you have time. It is done every single time without exception. A knife that is treated carelessly will show it — and so will the chef who owns it.
Rule 05
Pass a Knife Correctly
When passing a knife to another chef — always pass handle first, blade pointing away, laid flat on the counter if possible rather than handed directly. Never pass a knife blade first. Never place a knife near the edge of a counter where it could fall. These are safety rules that have become etiquette precisely because they are so consistently observed that breaking them is immediately noticeable.
Rule 06
Announce Your Movement
In a busy kitchen, when moving with a knife — say "sharp" or "knife" clearly. This is standard professional kitchen practice worldwide, not specific to Japanese kitchens. But in the context of Japanese knives it matters more — these blades are significantly sharper than Western knives and an accidental contact causes real damage. The announcement is not optional. It is basic kitchen safety that every professional internalises immediately.
Rule 07
Respect the Knife for What It Is
In Japanese culinary tradition a knife is not just a tool. It is the primary instrument of the craft. Japanese knife-makers spend years mastering their skill. The knives they produce are the result of centuries of refined technique. Using one carelessly — on the wrong surface, for the wrong task, without proper maintenance — is a form of disrespect not just to the object but to the tradition it represents. This is not sentimentality. It is the professional attitude that produces better work.
Why You Must Own Your Own Knives
The advice I received early in my career — own your own knives, do not rely on your employer — is worth expanding on because it goes deeper than just professionalism.
When you own your own knives you sharpen them to your angle. You maintain them to your standard. You know exactly what they feel like when they are at their best and when they need attention. You develop a relationship with the tool that genuinely affects your work. A chef who uses house knives is always working with an unknown variable — a blade sharpened by someone else to an angle they chose, maintained to a standard they set.
Beyond the practical — owning your own knives is a commitment. It is a statement that you take this seriously enough to invest in the right tools. In a professional kitchen that statement is visible and it matters.
Chef's Note
Your knife roll is the first thing people notice when you start in a new kitchen. Not the knives themselves necessarily — but whether you have them, how you carry them, and how you handle them in the first service. It tells experienced chefs everything they need to know about where you are in your development.
For Home Cooks — What This Means Practically
The professional etiquette translates directly to home use. You may not be in a kitchen where other chefs are watching — but the principles are the same because the reasons behind them are the same.
- Invest in your own knife — one good Japanese knife that is yours, maintained to your standard. Not a house knife, not borrowed, not shared with someone who will use it on the wrong surface.
- Learn to sharpen it properly — a whetstone is the correct tool. The skill takes an afternoon to learn and a lifetime to refine. Start now.
- Store it correctly — sheath, magnetic strip, or knife block with wide enough slots. Never loose in a drawer.
- Use it on the right surface — wood or rubber only. Glass and hard surfaces chip the edge immediately.
The etiquette exists for practical reasons. Follow it and the knife performs better and lasts longer. It is that simple. If you are ready to invest in your first proper Japanese knife — start here: the honest guide to Japanese knives under £100.
