JCK Natures Gekko Kiwami Series GEK-2 Santoku 180mm (7 inch)

Availability: Normally ships the same day

This high-grade version of the popular Gekko Damascus knife is truly worthy of the name “Gekko Kiwami” (Premium).

 After listening to the craftsman’s explanation about how these new Damascus knives are made, we recognized that their quality exceeds that of the original Gekko knife, due to the extra care and attention taken during their making process.

 Gekko Kiwami knife undergoes a special heat treatment process that uses a bath of molten salt, this allows very accurate temperature control and is a reliable way to create blades with a specific Rockwell hardness. It is often used for the production of small batches of blades, especially high quality knives and expensive custom knives.

 Gekko Kiwami knife has a natural-looking style, and that the polished layers of the beautiful unique & beautiful Tsuchime (“Hammered pattern”) textured Damascus blade. They feature a hand sharpened and hand honed VG-10 Nickel Damascus stainless steel blade (HRc. 60-61.).

 The handle is made of black pakkawood and the knife has a stainless steel bolster, which provides improved durability and good blade balance. The handle and bolster have a nice rounded shape that allows the knife to be held comfortably and securely.

 You can select the knife (with the Wooden Saya) or (Without Wooden Saya) at your preference. The matching wooden Saya (Sheath) with a decorative black lacquer finish, which nicely complements the Gekko Kiwami's black pakkawood handle and also the aesthetics of the Damascus blade.

 The tall blade and rounded nose / tip of the Santoku make it a versatile knife that is well suited to cutting meat, fish, or vegetables; Hence it’s name, which literally means “Three-purpose”. The Santoku is often recommended as a multi-purpose kitchen knife.

This knife has double bevel edge 70/30 which is suitable for right hand use.

For your information, many of the Japanese Kitchen knives come originally with double bevel edge sharpened 70/30 (face side/back side) for Western style knives. This geometry came from Japanese Traditional knives with single bevel edge and Shinogi blade construction. This is one of the special features and reasons why Japanese knives have an excellent cutting performance.

However, this 70/30 edge geometry is designed for right hand use, so we have a service to modify it to 30/70 for left handed users with re-sharpening process by skilled craftsman.

We believe quality and performance of Japanese knives are best in the world and hope you enjoy fine craftsmanship and spirits from your new knife. With proper cares, every Japanese knives can be your special cooking partner for long time.



This is the Stainless steel blade kitchen knife which has good rust resistance for easy maintenance. However even stainless steel blade kitchen knife has rust situation if you leave it with wet condition.

  • Before starting to use the knife, please wash it with water for cleaning up.

  • After using, please hand wash it and wipe it clean and dry with soft clothes. (Includes bolster and handle part)
  • This is an extremely sharp knife. Please use special cares in using and storing it.
  • Unlike German made knives, Japanese knife blades are ground to thin cutting edge for sharper cutting and easier re-sharpening. Please protect the edge from hitting hard materials to avoid chipping or cracking.
  • Please do not use it to cut bone or frozen foods, hard foods such as lobster and crab which have hard surface.
  • We recommend re-sharpening the knife using Japanese whetstones, when it gets dull.

    Awesome Christmas Gift

    I received the JCK Natures Gekko Kiwami Series GEK-2 Santoku 180mm (7 inch) knife for a Christmas gift. Not only is it beautiful, but it is very sharp and cuts wonderfully. It went through the Christmas Prime Rib like butter. Delivery was amazingly quick, also. I couldn’t be more pleased and am looking forward to my next purchase.

    JCK Natures Gekko Kiwami Series GEK-2 Satoku

    I have used edged tools since I was a child. I regularly use axes in my work. I use Gransfors Bruk axes, Randall Made knives, Case knives, and others. I am an expert knife sharpener. From Japanese Chef Knife I have purchased a Garasuki, a Nakiri, and several Santokus. The Santoku is the blade style I use most. A 6”or 6-1/2” blade is okay. I like the 7”. VG-10 is an excellent metal for all around use. It takes and holds an edge well. It is very resistant to corrosion. You can use it on acidic foods, leave it wet and have no problems. This knife has a 70/30 bevel. I am ambidextrous and prefer a 50/50 bevel. The 70/30 bevel presents no great dilemma. You may keep this bevel or eventually shape it to a 50/50 as you hone it over time. My favorite handle scale material is micarta. Pakka wood however, has proven its durability. At $117.00 this knife is a fantastic bargain. Most people will buy a $20.00 or perhaps a $50.00 knife that cannot take a keen edge and won’t hold an edge and ain’t worth throwing down the hill. This knife will take a good edge and hold it. It is a thousand times more valuable than a cheap knife for not much more cost. It must be honed and used properly in order to not destroy the edge.

    Very happy

    I bought this knife as a birthday gift for my boyfriend because he always cooks in our household and he’s also passionate about food. I am honestly very pleased with my purchase. I also had the handle engraved to make it more personalized. Highly Recommend to everyone that’s doubting it ;)
