For the 2026 Holiday Shopping Season, JCK has prepared special knife sets for your own kitchen or as a thoughtful gift for someone who enjoys cooking.

JCK Natures Black Thunder Damascus 4Pcs Knife Set

RAIUN Series: RD-1 Wa Petty 130mm, RD-2 Wa Santoku 170mm, RD-4 Nakiri 165mm, and RD-3 Wa Gyuto 210mm. Each knife comes with a black lacquered wooden Saya.

Flowing Damascus. Deep-toned wooden handles. Black Sayas to complete the mood.

RAIUN (雷雲) means “thundercloud” in Japanese. The vivid layers of Damascus steel and the dark tones of the wooden handles give these knives a dynamic presence, recalling the shifting patterns of clouds before a storm. For this Black Thunder set, we paired four Raiun knives with matching black lacquered wooden Sayas, giving the collection a distinctive character whether the blades are in use or covered.

We enjoy the contrast between the patterned steel, the natural grain of the dark wood, and the black lacquered finish of the Sayas. The oval-shaped Red-Sandalwood handles, finished with black Pakka Wood ferrules, bring warmth and a comfortable grip to the elegant Damascus blades. The black Sayas complement the handles without hiding the individuality of the wood.

Behind that appearance is a practical everyday knife: VG-10 stainless Damascus steel, hardened to HRc 60–61, with a 50/50 double-bevel edge sharpened and honed by hand. Good rust resistance makes these knives easy to welcome into daily cooking, while the fine edges reward careful preparation and regular whetstone sharpening.

We selected four useful blade shapes for this set. The Petty takes care of small, precise tasks, the Nakiri is dedicated to vegetables, and the Santoku and 210mm Gyuto give you two versatile choices for everyday preparation. Choose the blade that suits the ingredients and the way you like to cook.

The Black Thunder name describes the mood of this set, not a black coating on the blades. Its character comes from the combination of Damascus steel, dark wooden handles, and four black lacquered wooden Sayas. A set with a strong presence, made to be enjoyed at the cutting board rather than simply admired.

RD-1 Wa Petty 130mm (5.1 Inch) US$140: A compact, nimble knife for peeling, trimming, and slicing fruit and vegetables, chopping herbs, and making garnishes. Its narrow blade offers control for detailed preparation.

RD-2 Wa Santoku 170mm (6.6 Inch) US$191: A versatile everyday knife for vegetables, meat, and boneless fish. Its tall blade and rounded tip offer a practical all-purpose shape in a manageable size. Please note: The RD-2 Wa Santoku has a wider blade than a standard Santoku, so a standard Santoku Saya will not fit. In this set, it comes with a black lacquered wooden Saya designed for a Nakiri to accommodate its wider blade.

RD-4 Nakiri 165mm (6.4 Inch) US$191: A dedicated vegetable knife with a tall, rectangular blade for chopping, slicing, and mincing vegetables and fruit.

RD-3 Wa Gyuto 210mm (8.2 Inch) US$215: An all-purpose chef’s knife for vegetables, fruit, meat, and boneless fish. Its length provides reach for larger ingredients, while the pointed tip handles finer preparation. This set includes the oval-handled RD-3 model.

Dimensions & Weight

All four knives have 50/50 double-bevel edges and oval-shaped handles suitable for both right- and left-handed cooks.

These stainless steel knives offer good rust resistance, but should still be washed and dried promptly. Stainless steel can rust if left wet for prolonged periods.

• Wash before first use. Hand-wash only; do not use a dishwasher or leave the knives soaking in water.
• After use, wash the blade, ferrule, and handle carefully, then dry thoroughly with a soft cloth.
• Make sure each blade is clean and completely dry before placing it in its wooden Saya. Store in a dry place.
• Wipe the black lacquered Sayas gently with a soft cloth. Avoid abrasive cleaners that could scratch the finish.
• Protect the fine cutting edges from impacts and twisting. Do not cut bones, frozen foods, or hard shells such as lobster and crab.
• Use Japanese whetstones to re-sharpen when needed.
• Handle and store the sharp knives carefully, out of reach of children.
