JCK Natures Uzushio Series UD-2 Santoku 170mm (6.6 inch)

Availability: Normally ships the same day

Since my first glance, I knew that these beautiful Damascus knives should be called "Uzushio" (渦潮), which means "Whirling Tides" in Japanese. The beautiful and unique Vortex Damascus pattern of the "Uzushio" knife reminded me of tidal waves, which each have a unique shape that is constantly changing.

Each knife has a unique and beautiful Vortex Damascus blade. They feature a hand sharpened, hand honed VG-10 stainless steel blade core that is clad 
on both sides with 33 layers of nickel-stainless Damascus steel (HRc. 60-61. Double bevel blade with 50/50 symmetrical grind).

The knives feature a full-tang construction, Black Pakka Wood handles scales, a stainless steel bolster and stainless steel handle rivets/pins.

Whether you are looking to buy your first Japanese knife, or looking for a
 beautiful Damascus knife, our moderately priced range of high quality "Uzushio" knives are highly recommended.

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.

  • 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.

  • We recommend re-sharpening the knife using Japanese whetstones, when it gets dull.

    Review of JCK Natures Uzushio Series UD-2 Santoku 170mm (6.6 inch)

    This knife has been a pleasure to use and is extremely nice to look at it. It has completely changed my cutting game. The case is also really useful, but the lock for the case can be a Little annoying to use. Overall great knife.

    Excellent Quality and Service

    I bought this for a family member as a gift. He is very pleased with the product. He says it cuts better than any knife he's used, and he also likes the sheath that came with it to keep it (and his hands) safe. Shipping was fast and easy to track. I would recommend this site and these knives to others.

    Excellent knife

    I have many japanese knifes, including misono. And this knife is really really good. Nothing really to complain about. Handle is awesomw, fit and finish is great. VG10 is a hard steel, definitely harder than molybdenum. That is why it holds edge very well. By the way it is also assymtrically ground, that is why so many ppl find it so sharp ;) Damascus is also nice, but because it has etched structure it seems like it was rather engraved with laser or some sort rather than anything natural.
