Overview of the Features

The ​​Yoshihiro Shiroko Deba Japanese Knife is possibly one of the best Deba knives on the market, so it’s safe to say that there is a lot that this knife has to offer.

Below, we will shed some light on what this knife has that others don’t.

  • High-Carbon Steel Blade

The blade is what this knife is all about.

It is made out of high-carbon steel, and there is an extra amount of carbon used to make the blade harder and last longer.

The blade has an impressive score on the Rockwell Hardness scale at 62 – 63.

This is a really high score compared to most Deba knives on the market.

Plus, it is a white steel blade with a mist-pattern design on the edge called Kasumi, which translates to mist.

This pattern makes the blade more aesthetically pleasing.

Lastly, the blade is ground on one side, making it a single-bevel knife.

  • Premium Handle and Saya

This is quite a heavy knife, close to two pounds.

The handle boasts a traditional Japanese-style handcrafted Magnolia wood that has a rounded shape.

It is affixed to the blade with a Water Buffalo horn bolster and comes with a protective wooden sheath called a Saya.

The Saya does an excellent job of protecting the knife when not in use.

The heft of the blade and handle allows this knife to cut through the bones and heads of fish effortlessly.

Also, you’ll like that the pointed tip will allow you to clean fillet pieces.

  • Maintenance

This Deba knife comes with a limited lifetime warranty.

As such, you should learn how to properly maintain it so that it can last for a very long time.

Using the blade normally on fish will not cause it too much harm.

However, incorrectly sharpening, washing, and storing can do significant and even irreversible damages to the knife.

Make sure you are only handwashing the blade and drying it immediately so that it doesn’t rust or corrode.

You might also want to invest in a good Japanese knife maintenance oil to make the blade last longer.

When it comes to sharpening, always use a whetstone, and once you are done using it, store the knife in its protective sheath.
