White steel, also known as: Shirogami/White paper/Shiroko steel
This traditional steel is not named after its colour, but named after the colour of its paper wrapping, in which it is stored in the Hitachi steel factory in Japan. There are 3 grades of Shirogami white steel: #1,#2 & #3. From these 3, #1 contains the highest amount of carbon and #3 the lowest. Generally we say at our knifeshop, grade #1 can be made extremely sharp, but will be a little more fragile as #3. While #3 is a little softer, also easier to resharpen, but has less edge retention. Grade #1 & #2 is most common in white steels. White steel is a refined steel with a low percentage of iron, loved by many, as it is relatively easy to maintain. In practice it can be maintained with a whetstone and in a short amount of time it will become very sharp. This does not mean that these knives never have to be resharpened by a professional, even all knives in Japan need to be refurbished at a certain moment. This Shirogami steel is embraced by sushi chefs who demand extreme sharpness of their knives. White steel oxidates relatively quick and therefore needs to be maintained more often, but on the other hand you will get all benefits of this beautiful steel characteristics.
Elwin de Veld about HADO
The young craftsmen of HADO produce knives in tradiotional shapes and sizes. Traditional Japanese knives with double bevel, extremely hard to make but, if done as well as HADO does, extremely sharp edges. HADO is for now available in 3 series : white #2 kurouchi series (SUMI ), Ginsan with stainless clad ( Ginsan ) and White #1 with stainless clad ( Junpaku ). Where this last series is a rare combination. First of all, white #1 is difficult to forge, even harder with a stainless clad. Tanaka san is the master bladesmith behind HADO knives and produces these rare blades: Comfort of a stainless blade in combination with the extremely sharp white #1 core.
As I followed these young craftsmen closely, while they in Sakai were building their workshop, we joined in from the beginning of the HADO project. HADO purpose is not only to create knives which have an incredible sharpened edge, but also esthetically impress customers and share pleasures with them while using HADO knives. Unfortunately, due to the pandemic, we have not visited their workshop yet, but we are already planning for our coming trip to Japan.
