JCK Natures

JCK Natures Blue Clouds Basic Series BCA-7 Chopper 170mm (6.6 Inch)

Availability: Normally ships the same day

 Our "JCK Natures" house brand knives have proven to be some of our most popular knives. Each one of them has a unique appearance, fine characteristics and offers great value for money. Our JCK Natures knives are a fusion of the craftsman’s special artistic techniques and the magnificent scenery of almighty nature.

 The "Blue Clouds" knives each feature a simple design, this time, we are introducing a heavy-duty “Chopper” with a practical High Carbon Stainless Steel blade, which has good rust resistance and durability.

 The main focus of this Chopper Knife was practicality, so we chose a Simple Brown Pakka Wood Handle, which is durable and resists both water and shrinkage. Please note that the fit & finish of the handle and tang is a little rough and the Pakka Wood scales are usually slightly oversize, so they might not fit evenly with the tang. The manufacturer's craftsmen intend to provide a practical, secure grip for this heavy duty “Chopper” knife and they also wanted to produce this special purpose knife for a reasonable price, consequently, they deliberately decided to make these fit & finish compromises.

In Western-style cooking, people often need to cut hard foods and meat, such as chicken or fish, which might contains bones. Unfortunately, most Japanese knife manufacturers have stopped producing this type of special purpose knife due to low customer demand and a widespread decrease in the number of skilled craftsmen. Thankfully, the craftsman team in Seki City has continued to make these practical Choppers, which are perfect for heavy duty use or heavy-handed users.

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 fine craftsmanship and sharp edge with your new knife. With proper cares, every Japanese knife should be your special cooking partner for long times.



This is the Stainless steel blade kitchen knife that has a good rust resistance for easy maintenance. However, it may get rust, if kept in wet condition.

  • Please do not put the knife in the dishwasher machine for cleaning.
  • Please do not leave the knife in water or wet condition for long time.
  • After using, please hand wash the blade, bolster and handle thoroughly, and wipe it clean and dry with soft clothes, and keep it in 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.
