Japanese AUS-8 High Carbon Steel

Spectre SERIES

Japanese AUS-8 steel blades meet the standard of a tough, rust-resistant knife with a significantly long lasting razor-sharp edge. Carbon and Molybdenum explains its rigidity and high wear resistance, Chromium and Nickel increases mechanical strength and edge retention, and Manganese helps increase hardness, reduce structural wear, and makes for easy sharpening.

What Makes It Special

Why This Knife is Great

Every detail engineered for peak performance
Japanese AUS-8 High Carbon Stainless Steel
Provides a balanced approach to blade sharpness and edge retention, while providing a high order of rust resistance.
14-Degree Razor Sharp Cutting Edge
Each blade is hand sharpened to a perfect 14-degree angle per side, facilitating clean, precise cuts.
Mirror-Polished Durable Pakkawood
Used for military applications due to its incredible strength and exceptional density, Pakkawood has high water-resisting capabilities, won't crack or split, and is easy to clean and maintain.
Full Tang Strength
A knife with a full tang is one where the steel of the blade extends all the way through the handle. The extended blade improves balance and strength, which makes for a durable instrument that is built to last.
58 HRC on the Rockwell Scale
AUS-8 Japanese steel has a Rockwell Hardness (HRC) of 58 for maximum strength, flexibility, and blade edge durability.
Kessaku Spectre Series Knives are made with AUS-8 high carbon steel.

Japanese AUS-8 High Carbon Steel

BLADE FEATURE

Hand sharpened to a perfect 14-degree angle per side for clean, precise cuts and amazing edge-retention, the vacuum heat treated and nitrogen-cooled blades are crafted from high carbon Japanese AUS-8 stainless steel for enhanced corrosion resistance. They have a Rockwell Hardness (HRC) of 58, providing maximum strength, flexibility, & blade edge durability. AUS-8 steel also incorporates vanadium, which further improves the blade’s durability and edge retention.

Spectre Series knives are equipped with mirror polished pakkawood D-shaped handles

Mirror-Polished Durable Pakkawood

HANDLE FEATURE

Spectre Series handles have a contoured bolster which provides a comfortable pinch grip for enhanced knife control, and a stainless-steel laser etched end cap counterbalance. Pakkawood is used for both military and kitchen applications due to its incredible strength and exceptional density. It is nearly impervious to heat, cold, and moisture. The handle has full tang strength, which means the blade extends all the way through the entire handle, for lifelong durability and safety. Its seamless build ensures that no dirt or food debris can ever infiltrate its body, keeping the handle safe and hygienic in busy kitchens.

Questions?

WE HAVE ANSWERS

With proper care, your KESSAKU Professional Knives and Utensils can be your culinary companions for life. So, follow this guide to ensure continual optimal performance from all your knives and cooking instruments.

(These general rules should pretty much apply to all professional knives and cooking utensils by all manufacturers).

  a. Treat your professional knives and cooking instruments with respect and care. Our blades are extremely sharp so, exercise general caution, and of course, keep them out of the reach of small children. We include custom blade guards with all our knives for added safety as well as beautiful magnetic gift boxes which can be used for their storage.

b. The highly recommended method of cleaning professional knives is – quickly washing them by hand with a little detergent, followed by drying them with an absorbent towel. (*This is the standard operating procedure used by almost all professional chefs to keep their knives in optimal condition). We highly do not recommend putting these knives in a dishwasher.

c. Our knives use steels known for greatly enhanced corrosion and rust resistance. However, as with all professional knives, you never want to leave your knife soaking in soapy water. Over time, moisture and water will cause micro-corrosion in minute levels, which weakens steel. So, after use, clean your blades, dry your blades, and always keep your blades dry and stored properly.

d. In general, when washing cutlery, try to avoid soaps with bleach or heavy citrus extracts as they naturally promote corrosion.

e. Use proper and sane cutting surfaces. Wood, plastic, bamboo, and similar cutting boards are great! Glass, marble, ceramic, and granite surfaces can be damaged by knives (and cause the release of small particles of glass/ceramic/marble which is not really great to get in your food…), and these hard, counter-top type surfaces will also dull your knives.

Other IMPORTANT & HELPFUL TIPS!

As a practice, it’s always best to periodically hone and sharpen your knives while they’re still relatively sharp. Waiting for your knives to dull will make them take significantly longer to sharpen and hone. Quickly honing your blades after use retains a blade’s sharpness significantly longer, which means you’ll need to sharpen less often. Use the correct tool for the correct job. Our blades are astonishingly durable. However, for your own safety, the rule for using any knife from any brand is that you never want to force a cut by twisting the blade or prying. For example, you wouldn’t want to use a small paring knife to hack away at something extremely hard like a coconut or something deeply frozen. Instead, you should use a blade-type that’s suitable for such tasks, like a nice, heavy, cleaver.

HONING

When viewing a knife’s blade under a very strong microscope, its edge will look like a series of tiny points. Over time and frequent use, these points can get pushed down and bent out of shape.

Honing realigns and straightens that edge, removing an edge’s “burr” (the steel folding over itself) for smoother, safer, cuts. Regular honing will result in a less frequent need to sharpen.

SHARPENING

So, honing is for realigning a blade’s edge, by correcting misalignment. This differs from SHARPENING, which actually removes traces of steel from a blade’s edge to form a new edge.

Whetstones are considered the very best method of sharpening, as they’re more likely to ensure that your blade’s edge is restored to its original correct and proper geometry, allowing for maximum sharpness.

Thank you so much for your purchase and for joining the Kessaku family! As a member of
our family, you’re entitled to our worry-free lifetime warranty. It’s
automatically activated upon receipt of any Kessaku knife. Rest assured that we’ve got you covered.

You can use our Contact Us form, or email us at Help@KessakuUSA.com with any issue or concern so that we can immediately do our absolute best to make it right!

Please note that this warranty applies to manufacturing defects (which we’re very proud to define as “rare”) and, of course, does not include regular routine maintenance, like sharpening and honing, general wear and tear, or issues incurred through improper or unintended use.

With regular honing (every few uses), you'll only need to sharpen your Dynasty knife a few times per year depending on usage. The high-quality steel holds its edge exceptionally well.

Each Kessaku knife comes with a premium gift box with magnetic closure, felt-lined knife sheath, polishing cloth, care instruction booklet, and our warranty & support documentation.
