Set of Piece Japanese Knife Set - Yellow Sea Series: The Excellence of 67-Layer Damascus

Expert Summary at a Glance

  • Steel: 10CR15CoMoV core (60 HRC), San Mai construction with 67 Damascus layers
  • Performance: Long-lasting razor edge thanks to the cobalt-enriched alloy
  • Design: Amber yellow epoxy resin and stabilized wood handles — a sun-inspired aesthetic with perfect ergonomics
  • Value: Up to 48% savings compared to buying each knife individually

Technical Precision in Every Gesture: 10CR15CoMoV Steel

The Power of Cobalt and Carbon

The Yellow Sea Series represents the high-performance segment of Kaitsuko. The blade core is forged from 10CR15CoMoV steel, a premium alloy reaching a hardness of 60 HRC. The addition of cobalt maintains an extreme edge (15° angle) twice as long as standard steel. The 67 Damascus layers protect this hard core while providing the mechanical flexibility the blade needs.

Hammering and Unique Patterns

Every blade is a unique piece of craftsmanship. The folding and forging process creates natural wave patterns on the steel, while precision hammering reduces the contact surface with food — creating a natural non-stick effect during cutting.

Balance and Surface Science

A 60 HRC blade is a surgical precision instrument, but its rigidity makes it vulnerable on unsuitable surfaces.

  • The danger of plastic: Hard polymer or glass boards are technical enemies. They cause micro-rebounds that instantly dull the edge.
  • The end-grain advantage: We recommend using an end-grain cutting board. As highlighted by studies from the University of Wisconsin, wood possesses hygroscopic properties that trap and neutralize bacteria, while offering a "soft" surface that receives your Damascus knife's edge without breaking it.

The 7-Piece Set Breakdown: Absolute Versatility

This set has been rigorously composed to provide a technical solution for every culinary challenge:

Large Chef's Knife (234g): The powerhouse for large cuts of meat and voluminous vegetables.

Chef's Knife (191g): More maneuverable, it's the pivot of your kitchen for slicing and prepping everyday proteins.

Nakiri Knife (279g): Its rectangular blade is the Japanese standard for slicing vegetables without crushing them, preserving all their flavors.

Santoku Knife (244g): The master of delicate ingredients. Its geometry limits sticking for clean cuts on fish and tender vegetables.

Bread Knife (175g): A serration specifically designed to cut through the hardest crusts without tearing the crumb.

Boning Knife (125g): A rigid, precise blade for separating meat from bone with minimal loss. Note: designed to work around bone, not through it.

Utility Knife (217g): The ideal complement for all precision cuts requiring maximum agility.

Design and Ergonomics: The Yellow Sea Fusion

The handle is the essential point of contact between cook and tool. In this series, we use a blend of stabilized wood and epoxy resin:

  • Dimensional stability: Stabilized wood does not warp with moisture, guaranteeing lifetime durability.
  • Perfect balance: The balance point is engineered to reduce wrist fatigue during extended use.
  • Natural grip: The ergonomic shape ensures total control of every motion, even on the most complex cuts.

The Rigor of Selection

While the design draws inspiration from Japanese solar aesthetics, performance rests on the thermal mastery of 10CR15CoMoV steel. We selected this alloy for its molecular stability, delivering 60 HRC hardness (equivalent to Seki standards) with an optimized performance-to-price ratio.

We enforce strict end-of-production quality control: the final polish must reveal all 67 layers without a single imperfection — ensuring the Damascus pattern is not merely decorative, but the true mark of a successful multi-layer forge.

Care Guide for a Lasting Investment

A 60 HRC steel is a precision instrument requiring special attention:

  • Washing: Hand wash only with soapy water. Dishwashers are strictly forbidden (risk of micro-cracks in high-hardness steel).
  • Drying: Wipe immediately with a soft cloth. Thorough drying protects the resin handle's finish.
  • Cutting surface: Always use a wooden cutting board. Glass or marble surfaces would instantly dull your Damascus edge.
  • Technique: Never push food with the edge — always use the spine of the blade.

The 10CR15CoMoV steel of the Yellow Sea Series is harder than the majority of honing steels sold in stores.

  • What to avoid: Using a standard honing steel risks scratching your blade or causing chipping (micro-fractures) rather than realigning the edge.
  • Expert recommendation: For this alloy, maintenance is done exclusively on a Japanese water stone. Periodic passes on 3000 grit (maintenance) followed by 8000 grit (mirror polish) are essential to maintain the 15° angle and the original glide sensation.

The Kaitsuko Expert Verdict

The Yellow Sea Series is for those who have already mastered softer steels. It's an uncompromising instrument: 60 HRC hardness leaves no room for approximation - it demands precise technique to deliver incomparable cutting performance.

This 7-piece knife set is a long-term investment, backed by a blade guarantee. By choosing this set (individual retail value €900), you save €350 - an unmatched price-to-quality ratio for this level of forging craftsmanship.

Really amazing suit that looks like a million bucks!
Size: Large, Color: Black
This is the second suit we bought by Lupurty. The first was dark navy and fit so well and looked so good that we got one in black for our son’s wedding!

Disgusted!
Size: Small, Color: Black
I’m disgusted! I ordered this for my boyfriend to wear to prom. I ordered him a small and the jacket and the vest were not smalls, they look like they were a large. All three pieces had dog or cat hair on them and the jacket had dirt stains on the inside. They were all used! And some of the stitching was coming out! I’m so glad I received it the same day I bought it, because if received it closer to prom I would have been so screwed!!! Do not buy this or buy from this brand! Terrible product!!

Dress to Impress: Sharp, Tailored Fit, Quality Material, and Sizing Tips
Size: X-Small, Color: Navy Blue, Size: X-Small, Color: Navy Blue
This review is for the LUPURTY Men's Suits Slim Fit, 3 Piece Suits for Men, 2 Buttons Solid Jacket Vest Pants, Tuxedo Set (XS navy blue and black sets). I bought the XS knowing my son's measurements were actually below the size guide for that size, but I'm glad I did because it still worked out. The suit was a bit big—especially in the pants, which were quite long, and slightly roomy in the shoulders and arms—but it still looked sharp and well put-together. The overall fit has a clean, tailored appearance despite the extra room. The material feels high-quality and the color is true to what’s shown online. I do wish the black suit came with a black or gray tie instead of blue, which didn’t quite match. The suit in the photos is the navy blue set that my son wore to his 8th grade graduation, which matched their school colors perfectly. I also included my son’s measurements to help others with sizing: Weight 114 lbs Height 5'3" Chest 30.5" Waist 29" Hip 35" Sleeve length 21.5" Shoulder 17" Inseam 29" Back length 18.5"
