Over their 100+ year history, the Hinoura family of forge-smiths have developed a great deal of experience and expertise in the knife forging arts. 

The concept behind the collaborative knives that we have produced with Master Hinoura was simple: We both wanted to to produce superbly sharp, highly practical and aesthetically attractive high-carbon steel knives that would satisfy the needs and desires of knife enthusiasts who love high-carbon steel knives.

We requested that Hinoura uses White Steel No.1 for the core blade steel. It is sandwiched with outer layers of soft stainless steel. The laminated construction means that only the high-carbon steel blade core is likely to discolor or rust, since the outer layers of soft stainless steel are corrosion-resistant and easy to maintain. The layers of soft stainless steel also improve the blade’s resistance to impact and bending forces. White Steel No.1 is made by further refining White Steel No.2 and adding more Carbon. The extra Carbon allows it to achieve a slightly higher HRc. than White Steel No.2. It can be sharpened to an exceedingly fine edge, has very good edge retention and is easy to re-sharpen.

One of the Major Japanese Steel company Hitachi Steel Company’s capacity for producing the high grade cutlery steels including the White Steel No.1 is becoming very much limited. Under such circumstances, JCK is trying best to preserve the very purity and high cutting ability of White Steel No.1 Carbon steel knives with Master Hinoura.

This is the Custom Limited Edition Special Knife Collection. Beautifully polished and finished, Hinoura’s natural gradation color and taste of the modern & traditional Kurouchi Wa Santoku Knife is fitted a with a Innovative  Octagonal Soft Pink Turquoise Composite Stone Handle. Please feel the harmony of the traditional historical art and modern, high-sense design, quality.

The tall blade and rounded nose / tip of the Santoku make it a versatile knife that is well suited to cutting meat, fish, or vegetables; Hence it’s name, which literally means “Three-purpose”. The Santoku is often recommended as a multi-purpose kitchen knife.

More Information: Unlike many traditionally forged knives, Master Hinoura's knives have a relatively thick spine at the point where the tang enters the handle (The ‘neck'). In part, this because he forges these laminated knives using a piece of high carbon steel that is much thicker than that commonly used by other forge-smiths. The thick spine and neck makes the knife very strong, very comfortable to hold in a ‘pinch-grip’ and also results in excellent blade balance.

Although some people consider Master Honoura’s knives to be thick and heavy, their geometry is the result of carefully considering every aspect of their function. Contrary to what you might expect, the process of forging a thick blade 'to shape’ actually requires a lot of time and skill. Master Honoura’s knives are nicely tapered from their heel to the tip and from their spine down to the cutting edge, which is ground very thin behind the edge. We are confident that these knives will provide the high cutting performance that is demanded by Carbon steel lovers!

Knife Model: Custom Limited Edition, Hinoura White Steel No.1 Kurouchi Series HS1-4SP15 Wa Santoku 165mm (6.4 Inch)

Blade Material: White Steel No.1

Rockwell Hardness (HRc):  62 to 63

Blade Grind and Edge Shape: Double Bevel Edge 50/50

Handle Material:  Octagonal Soft Pink Turquoise Composite Stone Handle

Saya Included: No.

This knife comes with 50/50 double bevel edge geometry for both right and left handed use.

For your information, Japanese Kitchen knives are generally designed for right hand use with a slightly thicker and rounded grinding on the right side blade and a less rounded (almost straight flat) grinding on the left side blade. However, both right and left hander can use the knives that have double bevel edge sharpened 50/50 without problems. 

We believe the quality and cutting performance of Japanese knives are the best in the world, and hope you enjoy the fine craftsmanship and its sharp edge of your new knife. With proper cares, every Japanese knife should be your special cooking partner for a long times.

Important

This is the Carbon steel blade kitchen knife that can get rust and discolor easily, and requires extra cares and attentions to prevent rust.

• Please do not put the knife in the dishwasher machine for cleaning.
• Please do not leave the knife in water or wet condition for a long time.
• After using, please hand wash the blade, bolster and handle thoroughly, and wipe it clean and dry with soft clothes. Please apply Tsubaki oil on the blade and keep it in a dry place.
• This is an extremely sharp knife. Please use special cares in using and storing it.
• Unlike German made knives, Japanese knife blades are ground to thin cutting edge for sharper cutting and easier re-sharpening. Please protect the edge from hitting hard materials to avoid chipping or cracking.
• Please do not use it to cut bone or frozen foods, any hard shell foods such as lobster and crab.
• We recommend using Japanese whetstones to re-sharpen the knife, when it gets dull.
