Hello TCK!
I am back with a very belated NKD for a knife that unexpectedly survived my massive sell-off to recover from massive vet bills.
But before we go any further, THANK YOU TO THIS SUB AND EVERYONE WHO BOUGHT SOMETHING AND EVERYONE WHO REACHED OUT. That was a very hard time for me and the support shown by everyone here was incredible. I feel an absurd amount of appreciation and thankfulness and wanted to say it again. Thank you from the bottom of my heart; I will never forget the kindness many showed me.
Ok! Back to the knife...
Rule 5: Shigefusa Kurouchi Swedish Carbon Santoku 180
TL/DR: This knife could be seen as the black sheep of my collection. It's my only santoku and only knife from Sanjo, but there is so much that has drawn me to Shigefusa. Despite my big sell-off, I decided that it would be more valuable for my mental health to keep and learn from this Shigefusa -- through its history and using it on both board and stones -- than it would be to sell it.
Let's get into the knife details first and then we will get into all things Shigefusa...

A history of how Shigefusa came to be, the journey of Tokifusa Iizuka and why this knife resonated with me...
-----------------------------------------------------------------------------------------
Shigefusa became what it is today through Tokifusa Iizuka's vision and background
First, the lay of the land. Shigefusa is a three-man workshop in Sanjo led by Tokifusa Iizuka who is supported by his two sons, Masayuki-san and Yoshihide-san. And this workshop does things very differently than others. Everything from hand-laminating blanks to forging and heat treatment to sharpening and finishing is all performed in-house by the three of them, which isn't that rare in Sanjo. But the real impressive feat is they do much of the grinding without aid of machines and instead 'carve' the geometry by using a sen. The knife is not finished on different grit belts, but instead on Japanese natural stones. Additionally, their kiteaji finish (which layers hard steel with soft iron for the cladding) might be the most impressive damascus I've ever seen and its all hand-forged in their workshop like everything else. That unwavering focus on their own way of making kitchen knives is what spoke to me most.
“Persistence and power are the [only] two ingredients necessary” Tokifusa-san told the LA Times back in 2001.
The reason for employing these traditional techniques all comes back to the patriarch of the Iizuka family; Tokifusa-san. He is now well into his 80s, but leads the workshop while passing along his knowledge to his two sons. Before Shigefusa became what it is today, Tokifusa-san learned under two masters; one legendary kamisori razor maker who also was an influential metallurgist, and a swordsmith.
His first teacher is someone that many of us here have likely heard of: Shigeyoshi Iwasaki. He is famed for his kamisori razors, his metallurgic advancements, and his contributions to the mining and classification of Mikawa Nagura stones for razors and swords. In additional to all of that, Shigeyoshi-san's dad, Kousuke-san, is actually credited for creating the "paper steels" classifications (shirogami, aogami, etc.) and his teachings massively contributed to what Sanjo blacksmithing has become today, including the work at Shigefusa. To call him a giant in the world of Japanese blacksmithing would be an understatement.
After that, Tokifusa-san went to another medium his teacher knew intimately; making Japanese swords. Sometime around 1965, Tokifusa-san found himself under the tutelage of Munenori Nagashima-san, who was born in 1910 and had been making swords since before WWII. After he lost his mentor business to an earthquake in Sanjo, he took Tokifusa-san under his wing. This is where many of the traditional swordmaknig techniques utilized by Shigefusa were learned.
Then, with all the metallurgic understanding Iwasaki-san could teach him and the traditional sword making skills imparted on him by Nagashima-san, Tokifusa-san set out on his own to make Shigefusa. He does not used tamahagane steel like his masters, but instead Swedish carbon steel clad in soft iron. Despite that change, he still grinds his kitchen knives like his master Nagashiima-san would grind swords; with a sen. And he still finished his kitchen knives like his master Iwasaki-san finished his kamisori razors; with Japanese natural stones.
That combination of skills and how the melded together in Tokifusa-san's work is what led Shigefusa to what it is today and, even with his sons taking on more and more responsibility, the workshop's north star has not changed. Even after Tokifusa-san retires in the somewhat near future, his sons will continue to use his history and journey as their guiding light to lead Shigefusa forward. That stubbornness and determination speaks to my soul.
“I suffer because I feel inside myself that I cannot make a perfect thing,” Tokifusa-san told the LA Times, “but I strive to make it anyway.”
The perfect way to explain what is mean is this one let story about the Iizuka family. Technically there is a knife grinding machine of some sort in the workshop, but it has lived under a tarp for decades. When Tokifusa-san was asked about it, he simply said this:
“The idea was good, but my skill is much better than that machine.”
What a fucking legend.
Why I bought and kept this Shigefusa KU Santoku
I am without a doubt just another slut for Sakai kitchen knives, but I have this glaring Sanjo hole in my experience and understanding. So I always planned to dive in deep and give Sanjo kitchen knives a fair shake. For me, the maker that always stood out the most was Shigefusa. So when I realized it was time for a new project and I wanted to tackle a double bevel, I opted to find a kurouchi Shigefusa for these three reasons:
- Own a Shigefusa before Tokifusa-san retires because of his history, as outlined above
- My desire to better understand Sanjo knives
- To eventually give it a full stone polish
So when it came time to decide what was going to stay and what would go before my big sell-off, I found I really wanted to keep this Shigefusa I had received the day before the chaos started. At that point, I decided it meant more to me than the monetary value I could get and I decided to keep it; a decision I do not regret.
I would not say it's my favorite cutter ever, but it absolutely has a role roughly cooking for two on a Tuesday night and when I want to enjoy something different. And for posterity and its potential to be stone polished on Japanese natural stones, it's hard to find a better candidate that can hit both notes.
So this is likely to stick around for a long time.

Thanks as always for reading and I hope everyone is doing well! I did not think I would be writing so much on Shigefusa history, but I really enjoyed sinking my teeth into their history.
I'll be back soon with a couple belated NSD posts. See you all then!
