JCK Natures Black Moon Series BM-7 Nakiri 165mm (6.4 inch)

Availability: Normally ships the same day

 These distinctive knives are the sister series to our popular JCK Natures “Blue Moon" knives and they are expertly handcrafted by the same team of craftsmen. The knives have a traditional hammer forged blade and a dark Kurouchi (“Black forged”) finish that reminded us of the cratered surface of the moon, which inspired us to name them “Black Moon”, which is 黒月 Kokugetsu in Japanese.

 The knives have a blade core of Hitachi White No.2 Japanese high carbon steel, which is sandwiched between two layers of soft iron. We think the transition between the inky-black Kurouchi finish, the silver-gray soft iron and the brilliant White No.2 steel is particularly attractive. "Black Moon" Kurouchi knives have a very good overall level of fit and finish — just like the "Blue Moon" series — and each one is hand ground and sharpened. 

 The oval-shaped Charred Chestnut wood handle (Black resin ferrule) is suitable for both right-handed and left-handed users and it beautifully matches the style of the black and silver-gray blade. Charred chestnut wood handles have been used in Japan for centuries because they offer a secure grip, even when your hands are wet.

 The Nakiri is a double bevel edged knife that is rectangular in profile and has a tall, thin blade. It is popular throughout Japan and is often used by home cooks for quickly and efficiently chopping, slicing or mincing vegetables and fruit. It is becoming increasingly popular with vegetarians.

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 the quality and cutting performance of Japanese knives are the best in the world, and hope you enjoy the fine craftsmanship and its sharp edge of your new knife. With proper cares, every Japanese knife should be your special cooking partner for a long time.



This is the Carbon steel blade kitchen knife that can get rust and discolor easily, and requires extra cares and attentions to prevent rust.

  • Please do not put the knife in the dishwasher machine for cleaning.
  • Please do not leave the knife in water or wet condition for a long time.
  • After using, please hand wash the blade, bolster and handle thoroughly, and wipe it clean and dry with soft clothes. Please apply Tsubaki oil on the blade and keep it in a dry place.
  • 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, any hard shell foods such as lobster and crab.
  • We recommend using Japanese whetstones to re-sharpen the knife, when it gets dull.

I thought the blade had a little too much heft and was too thick but after prolonged use I grew to enjoy using it, great edge can be had and great value.

Great value

This knife truely looks stunning. Only the handle could've been ground better so that the gap between wood and resin isn't there but that's only a really small gap anyway. The wood and the texture look amazing and it've become one of my most used knives, especially for cutting vegetables. It stays sharp quite long and is easy to sharpen, all in all I'd reccomend it to anyone looking for a really good budget knife for mainly vegetables.

Outstandng knife

The Blue Moon Nakiri knife has been a wonderful knife for both value and beauty. A rustic knife that has stayed sharp and has become the favorite knife of everyone that I have gifted one to. These make wonderful gifts for home cooks. A vegetable knife that is a pleasure to work with. Don't hesitate to purchase when these come back in stock. The carbon edge can rust if not properly cared for. Well worth maintaining.

Great knife great price.

The knife is gorgeous and sharp. Chops herbs in a flash. I let the blade sit with water on it for a little to long and the blade started to oxidize a little bit. Looks even sweeter now.
