Responding to Customer Requests
-
Listening Beyond the Blade
At KIREAJI, every customer request is more than an inquiry — it is the beginning of a conversation.
We work closely with the skilled artisans of Sakai City to bring exceptional Japanese knives to customers around the world. Each request, whether simple or rare, reflects a personal story, a culinary ambition, or a deep respect for craftsmanship.
Rather than offering standardized solutions, we listen carefully and respond thoughtfully — sometimes developing entirely new projects to honor a single voice.
Below are selected examples of how we have responded to our customers’ aspirations and transformed their requests into meaningful outcomes.
-
1. Upgrading to a Custom Handle – Elevating craftsmanship with premium materials –
-
-
Customer Request
Ginsan Damascus Yanagiba (Sakimaru) 400mmA customer from the USA, Mr. J, wished to enhance his Ginsan Damascus Yanagiba (Sakimaru) 400mm by upgrading the standard Ebony handle to the more distinctive and luxurious Snakewood.
-
KIREAJI’s Response
We consulted closely with Shiroyama Knife Workshop in Sakai City to evaluate the balance, grain pattern, and durability of Snakewood for this exceptional blade.
Snakewood is admired for its striking natural pattern and density, offering not only visual richness but also a refined tactile experience in hand.
By carefully matching the handle to the blade’s character, we created a custom piece that elevated both performance and presence — transforming the knife into something deeply personal to its owner.
2. Developing a Left-Handed Knife – Bridging tradition and innovation –
-
-
Customer Request
Mr. John from the USA shared his strong desire to own a left-handed Japanese knife crafted in Sakai City — a request that reflects both passion and patience, as left-handed traditional knives are extremely rare.
-
KIREAJI’s Response
Recognizing the technical complexity involved, we began developing a rare Super Steel (Honyaki) Yanagiba (Sakimaru) 300mm – Left-handed model.
Creating a left-handed Honyaki blade requires rebuilding the geometry from the ground up. It is not a simple mirror adjustment, but a full reconsideration of balance, grind, and heat treatment — all executed by skilled Sakai artisans.
The project is currently in development, entirely handcrafted, with an estimated completion time of approximately two months.
Beyond fulfilling one customer’s request, we also decided to expand our left-handed collection, so that passionate left-handed users around the world are no longer overlooked.

4. From Uncertainty to Confidence: Finding the Right Japanese Knife
-
Customer Request
We regularly receive inquiries from around the world from individuals seeking a knife that truly fits their cooking style.
One customer from the USA asked for “a knife suited to everyday cooking” and expressed a wish to build a cohesive set with matching handles — combining function with visual harmony. -
KIREAJI’s Response
In-Depth Personal Consultation
Rather than recommending a single popular model, we began by understanding how the customer cooks — the ingredients most frequently used, cutting techniques, kitchen environment, and long-term goals.
Carefully Curated Recommendations
Based on this dialogue, we presented several thoughtfully selected options, clearly explaining the balance, steel characteristics, maintenance considerations, and aesthetic details of each knife.
To honor the request for unity, we ensured that the handles aligned in material and tone, creating a set that feels intentional and refined.At KIREAJI, selecting a knife is not a transaction — it is a process of discovery.
We believe the right knife should not only perform beautifully, but also inspire confidence and rhythm in your daily cooking.If you are searching for a knife that truly belongs in your kitchen, we invite you to connect with us through our “Contact Us” page.
5. Looking for Traditional Japanese Knives Crafted by Master Artisans?
-
Customer Request
A customer from the United States reached out in search of a 300mm Ginsan Yanagiba forged by master artisan Shogo Yamatsuka — a blade not currently listed on the KIREAJI website.
The request reflected a deep appreciation for craftsmanship and a clear understanding of the artisan behind the steel.
-
KIREAJI’s Response
Rather than limiting the selection to what is displayed online, we directly contacted Shiroyama Knife Workshop in Sakai City to inquire about the availability of this specific blade.
After confirming stock and production details, we provided the customer with comprehensive information regarding availability, specifications, and purchasing options.
At KIREAJI, our role extends beyond what appears on our website.
We strive to serve as a trusted bridge between discerning customers and the master artisans of Sakai — ensuring that even rare and unlisted pieces can find their rightful owner.
6. Looking for a Japanese Knife Blade Only?
-
Customer Request
“I want to attach my own custom handle.”
“I prefer to refine the sharpening myself, so I only need the blade.”We often hear from passionate cooks, sharpeners, and craftsmen who seek not a finished product, but a starting point — a traditional Japanese blade ready to be shaped into something uniquely their own.
-
KIREAJI’s Response
To support this level of dedication, KIREAJI collaborates directly with Shiroyama Knife Workshop in Sakai City to confirm the availability of the requested blade.
Once stock and production details are verified, we provide a detailed quotation. Upon agreement, we arrange the sale of the blade only, carefully prepared for international delivery.
-
Important Notes
– This option includes the blade only. A wooden sheath (saya) and final sharpening (honbazuke) are not included.
– As each knife is handcrafted, availability is limited and lead times may vary depending on production conditions.
At KIREAJI, we respect those who wish to complete the final chapter themselves.
Our role is to serve as a bridge between Sakai’s traditional craftsmanship and individuals who seek deeper involvement in the making of their knife.If you are searching for a specific blade, we invite you to contact us.
7. Looking for Traditional Japanese Knives and Authentic Accessories?
-
Customer Request
Beyond inquiries about traditional Japanese knives, many customers from around the world have asked whether KIREAJI could offer the natural whetstones used by Sakai artisans to achieve their finest edge.
Some also expressed interest in traditional accessories such as Moribashi plating chopsticks and knife bags — seeking not only tools, but a deeper connection to Japanese culinary culture.
-
KIREAJI’s Response
Introducing the Ōhira Natural Finishing Whetstone
In response, KIREAJI has carefully introduced a Japanese natural finishing whetstone — selected for its authenticity, refinement, and ability to reveal the true character of a blade.Unlike synthetic stones, a natural finishing stone such as Ōhira interacts uniquely with each blade, enhancing both sharpness and surface beauty in a way that reflects centuries of sharpening tradition.
-
Authentic Accessories to Complement the Experience
We also offer select traditional accessories, including Moribashi plating chopsticks and knife bags, available when ordered together with a knife. These pieces are chosen to complement the spirit of craftsmanship rather than merely add function.
At KIREAJI, our mission extends beyond providing knives.
We aim to share the full ecosystem of Sakai craftsmanship — from forging, to sharpening, to presentation — one thoughtful request at a time.
8. Looking for Rare Honyaki Knives by Legendary Japanese Craftsmen?
-
Customer Request
A customer from the United States asked whether KIREAJI carries Honyaki Mizuyaki knives forged by Genkai Masakuni, a rare master who inherited the techniques of the legendary Masakuni Okishiba.
They also inquired about blades sharpened by Gen Hakuho, widely regarded as one of the greatest edge finishers in modern Japanese history.
-
KIREAJI’s Response
Yes — KIREAJI is honored to offer a carefully curated selection of Honyaki Mizuyaki knives by Genkai Masakuni, available only in extremely limited quantities.
Honyaki Mizuyaki represents one of the most demanding techniques in Japanese bladesmithing. Forged from a single piece of high-carbon steel and hardened through precise water quenching, each blade carries both extraordinary sharpness and significant risk during production. Only a handful of craftsmen in Japan possess the skill and confidence to execute this method successfully.
-
About Genkai Masakuni
Genkai Masakuni (Yoneo Muko) is a legendary bladesmith known for mastering Mizuyaki Honyaki through decades of dedication and independent study. Though often associated with Masakuni Okishiba — widely known as “Heianjo Okishiba” — his techniques were developed through his own pursuit of perfection.
Today, Genkai Masakuni produces exceptionally rare blades that embody discipline, restraint, and uncompromising craftsmanship.
For collectors and professionals seeking the pinnacle of Japanese knife artistry, these knives are not merely tools — they are living expressions of a historic tradition.

Voices from Our Customers

Every knife carries a different purpose.
Every conversation begins with a different story.
Over time, customers from around the world have shared their experiences with KIREAJI — not only about the knives themselves, but also about the dialogue, customization process, and craftsmanship behind each piece.
Some speak about the sharpness and balance of the blade.
Others reflect on the patience, care, and communication that shaped their experience from beginning to end.
These are not scripted testimonials or marketing messages.
They are quiet reflections from individuals who chose to walk this journey with us.
As one customer kindly shared:
“Product is great as well as customer service.”

A Cycle of Listening, Refining, and Evolving
-
-
Every request we receive is more than a question about a product. It is a moment to listen—with sincerity and attention—to the voice behind it.
We believe that by continuing this cycle of listening, refining, and evolving, our service does not simply improve—it becomes more honest. And through that honesty, it continues to grow.
Each refinement we make is shared back with our customers. With every step, we move a little closer to what our service is meant to be.
Through this ongoing process, we believe something greater begins to take shape. The circle of appreciation for Japanese knives quietly expands—one conversation, one improvement at a time.
The road ahead will not always be easy. There will be challenges, uncertainties, and moments that test us. But we remain committed to facing each one with sincerity and care.
Our hope is to carry this tradition of Japanese knives into the future, step by step, through the work we do today.
If our efforts can contribute, even in a small way, to that future—there is no greater fulfillment for us. -
Why We Listen — and Why It Changes Everything
-
There is a version of customer service that is really just complaint management. Someone has a problem. You fix it, or you don't. The interaction ends. Nothing changes.
That is not what we are trying to do.
At KIREAJI, every message we receive from a customer is treated as something more than a request to be processed. It is a window — into how people around the world are encountering Japanese knives, what they are hoping for, what the current limits of our service actually are, and where the next meaningful step might be. We listen not simply to respond, but to understand.
-
What Listening Has Actually Produced
We want to be specific about this, because "we value your feedback" is one of the most hollow phrases in the language of business. So instead, let us tell you what listening has actually led to.
A customer in the United States wanted to upgrade the handle on his Ginsan Damascus Yanagiba — not to the standard option, but to snakewood, a material prized for its striking grain and density. This was not a catalogued option. It required us to work closely with Shiroyama Knife Workshop in Sakai to evaluate whether the wood's properties were a genuine match for the blade's character — its balance, its weight, its presence in the hand. The answer was yes. The knife was made. One person's specific vision became a real object.
Another customer, also from the United States, asked for something rarer still: a left-handed Honyaki Yanagiba. Left-handed traditional Japanese knives are not simply right-handed knives reflected in a mirror. The geometry must be reconsidered from the beginning — the grind, the balance, the heat treatment, all rebuilt for a different hand. This is complex work, and it is currently underway. But beyond fulfilling one customer's request, we made a decision: to build a left-handed collection, so that passionate left-handed cooks around the world are no longer treated as an afterthought.
A customer from the United Kingdom wanted knives that suited their everyday cooking — and wanted them to form a coherent set, with handles that matched in material and tone. This required a different kind of listening. Not to a specification, but to a way of cooking, a kitchen environment, a long-term aspiration. We asked questions. We learned how they cooked. We presented options that were not simply popular, but genuinely appropriate — and we made sure the handles aligned, because someone who cares about that detail deserves to have it honored.
A customer from China was looking for a 300mm Ginsan Yanagiba forged by master artisan Shogo Yamatsuka — a blade not listed on our website. Rather than apologizing for the gap, we contacted Shiroyama Knife Workshop directly, confirmed availability, and came back with a complete answer. The knife existed. The customer received it.
Customers who build their own handles, or who prefer to do their own final sharpening, asked whether they could purchase blades only. We now accommodate this — working with Shiroyama to confirm availability, preparing blades for international delivery, and respecting the fact that some people want to complete the final chapter of the knife themselves.
Customers planning visits to Japan asked whether they could visit Shiroyama Knife Workshop in person. We coordinate those visits — liaising with the workshop, confirming scheduling, making sure that what could have been a closed door becomes an open one.
A customer planning a long-term hotel stay in Japan asked whether their knife could be delivered to the hotel. We arrange this manually, managing every step of the coordination because our website is not configured for domestic Japan transactions and the alternative — simply saying no — was never acceptable to us.
Customers asked about the whetstones that Sakai artisans use. We introduced the Ōhira natural finishing whetstone. Customers asked about traditional accessories — moribashi plating chopsticks, knife bags. We made these available alongside knife orders.
A customer asked to be notified whenever new work emerged from Sakai. We added an email subscription to every page of the site.
These are not large gestures. They are small ones, made consistently, in response to real voices. And together, they have shaped what KIREAJI actually is — not what we planned it to be, but what our customers showed us it needed to become.
-
On Sincerity, and What It Demands
The Japanese word makoto — which we think of often — describes the alignment between what is true and what is presented. To act with makoto is to ensure that the outside matches the inside, that what you offer is genuinely what you say it is.
We think about this when we receive a customer's message.
It would be easy to respond to every inquiry with warmth and efficiency and still remain fundamentally unchanged. To answer the question, close the ticket, and move on. This is what most businesses do, and it is not dishonest, exactly. But it falls short of makoto. It treats the customer's voice as a problem to resolve rather than a signal to follow.
We believe that if someone takes the time to tell us what they need, we owe them more than a polite reply. We owe them a genuine attempt to understand why they need it, whether we can provide it, and if not — what would have to change for us to be able to.
Sometimes the answer is immediate. Sometimes it takes weeks of coordination with Shiroyama. Sometimes it leads to a decision that changes what we offer to everyone, not just the person who asked. But the direction is always the same: toward the customer's actual need, rather than toward the edges of our existing catalogue.
-
Why This Matters Beyond the Transaction
We are not simply trying to become a better retailer. We are trying to do something more specific: to be a genuine bridge between the craftspeople of Sakai and the people around the world who want to connect with what they make.
A bridge that only carries traffic in one direction isn't really a bridge. If we only deliver knives outward from Sakai and never carry understanding back — about what people want, what they are missing, what questions they are asking, what the real limits of our service are — then we are not doing the work that a bridge should do.
Every customer request that we receive is information flowing in the right direction. It tells us something about the gap between what Sakai's craft has to offer and what the world currently knows how to receive. Closing that gap, one request at a time, is the actual work.
The road ahead will not always be easy. There will be requests we cannot fulfill. There will be coordination that takes longer than it should. There will be moments when the complexity of what we are trying to do becomes genuinely difficult. We know this.
But we remain committed to facing each of those moments with the same disposition: listening first, responding with honesty, and using what we learn to move a little closer to what this service is meant to be.
Because when that happens — when a person who has been overlooked by the industry finds exactly the knife they were looking for, or when someone's specific vision becomes a real object in their hand, or when a visit to Sakai becomes possible for someone who thought it wasn't — something larger than a transaction takes place.
The circle of people who truly understand and love Japanese knives grows by one more person. And that, quietly, is how a tradition carries itself forward.
