JCK Natures ”Gekko Blue” Petty 135mm (5.3 inch)

Availability: Normally ships the same day

From my first glance of this beautiful knife, I knew it should be called "Gekko”, or 月光, which means "Moonlight" in Japanese. From every angle, the Gekko knife reminded me of the way that the shape and light of the Moon changes each night.

Beautifully mirror polished VG-10 stainless steel blade core that is clad on both sides by a 33 layer Damascus stainless steel (HRc. 60-61. 50/50 symmetrically ground double beveled edge). 

We specially requested the Craftsmen to make extra attention and care for making precise and detailed edge by hand-sharpening process.

Stylish “Blue Pakka Wood Handle” matches well with beautiful mirror polished Tsuchime Damascus blade.

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

A mainstay of professional Western kitchens, the Petty knife is a small general-purpose knife used for peeling, shaping, and slicing fruits and vegetables, chopping herbs, and making garnishes. The compact size and relatively narrow blade of the Petty knife mean that it is very nimble and controllable, thus it is ideal for making precise cuts.

This knife comes with 50/50 double bevel edge geometry for both right and left handed use.

For your information, Japanese Kitchen knives are generally designed for right hand use with a slightly thicker and rounded grinding on the right side blade and a less rounded (almost straight flat) grinding on the left side blade. However, both right and left hander can use the knives that have double bevel edge sharpened 50/50 without problems.  

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 knife can be your special cooking partner for long time.

  • 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.

    JCK Natures “Gekko blue” 135mm petty, and case.

    Sharp, stays sharp. But it is also beautiful, and a practical knife for camping holidays on the boat. Bought as a present for my wife. Many a brownie points earned. No even expensive for such a lovely thing.

    Beautiful .

    Just what I was looking for aesthetically and size wise. Very beautiful and seems well made. It could have been a little sharper on arrival but was decently sharp. Shipping was surprisingly fast.

    Favorite knife of my wife and mother-in-law

    I bought it for my wife as it is super pretty and she likes smaller knives. It's become her favorite knife now. And when my mother-in-law comes to visit, this is the knife she always grabs when she wants to do something in the kitchen. Looks like I need to buy a second one as a gift. I also borrow it sometimes. The knife is very stiff and rigid and has some mass to it. It is perfect for cutting broccoli and cauliflower and breaking down chickens. Handle is super comfortable, but I did want to round out the spine and the chin. They were quite sharp. Edge was very sharp out of the box. It could shave hairs of my forearm. It was not a clean shave, but it cut. Since it's made out of VG10, I know it will be very easy to sharpen, but so far I did not need to. It's been over a year, and it's still plenty sharp.

    Beautifully crafted

    I bought this as a gift for my husband and he absolutely loves it - the look, the blade and just how well crafted it is all round. This is our second purchase and would highly recommend both!
