Zan shin(残心)- Kaz's original knife brand

"Zanshin" translates as to keep ones mind. It is a mindset that we should retain our tension after completing a single action and be prepared for the next. For example, in a kendo match, even if you win, those who care Zanshin mindset do not show their joy, meaning that even if you defeat your opponent in front of you, he may still be attacking you again, or there may be a second opponent behind him. So, it is important to always remain focused and keep your mind calm.

In kitchen knives too, we chose this name in the hope that people will not be distracted when cooking, sharpening knives, or in any other situation, and that they will safely prepare delicious food and keep their knives sharp.

The VG10 Zanshin knives represent the pinnacle of culinary craftsmanship, meticulously fashioned by Sumikama Cutlery, a venerable entity situated in Seki, Japan, with a legacy tracing back to its foundation in 1916. Inheriting the esteemed tradition of swordsmithing that spans nearly eight centuries, Sumikama has seamlessly transitioned this rich heritage into the realm of kitchen cutlery, exemplified by their globally renowned "Kasumi series" of premium kitchen knives.

 

Introduction of the new Zanshin Sora series

Introducing our lightweight and thin blade designed to effortlessly glide through food ingredients, reducing friction for a seamless cutting experience.

The meticulous craftsmanship includes a large Kireha (edge line) and an intricately hammered pattern for an elegant touch. Compared to the Zan Shin Ao series, the Sora series boasts a thinner blade, enhancing sharpness while requiring gentle handling to prevent chipping. However, its notable advantage lies in easy restoration and resharpening using mid-grain whetstones.

Available in various sizes tailored to different culinary needs, our 16.5cm Bunka or Santoku knife is ideal for beginners, while the 15cm Bunka or 12cm petty knife serves as a versatile second option.

Crafted with a walnut handle featuring a double-sided chestnut shape, our design ensures comfort and functionality for both right and left-handed users.

 

Hammered finish and hazy sky pattern

The blade of the Zan Shin Sora series exhibits a striking contrast, featuring an image reminiscent of rocky terrain juxtaposed against a hazy sky, evoking a sense of mystique.

Kaz's Knife "No worries, Minor-Issue Warranty"

Having been used for a while, even good knives can get chipped and rusty as seen in the above video, but don't worry! 

Most of the minor issues can be fixed by sharpening on a #400-#1000 whetstone. We have tutorial videos for you to learn how to use whetstone. However, it might seem a bit hard work to get it done by yourself.

Kaz's knife is offering "Minor-issue warranty" which covers small chips and rust on the knives you purchased from us. You can always contact us when you feel your knife became dull, chipped, rusty, etc. We fix those minor issues and send the sharpened knife back to you, mostly for free of charge! (depending on how much work is required, also you bear the postage for sending the knife to us)

(*) Please be advised, we do not warrant major issues caused by misuses such as dropped, cutting bones or frozen food, putting too much force into hard materials, etc.
