 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”.

    Quick and light

    This is my first time buying a good knife and japanese, so I didn’t know how good it was going to be. The cut is amazing, the knife is so light and so sharpened that you don’t feel the movement of your hand!

    JCK Natures Raiun Series RD-2 Wa Santoku 170mm (6.6 inch)

    From searching the site for just the perfect knife for my wife to use, to ordering, and after we received the knife, dealing with Mr. Iwahara’s “JapaneseChefsKnife.com” was an excellent experience! We received the knife in a very reasonable amount of time after the order. Actually, we were quite impressed that it got to as fast as it did given that it came form Japan! The knife itself is absolutely spectacular in appearance, function, and quality. It handles incredibly well, is very versatile, and is far and away the sharpest knife we have. It’s price made it a serious bargain. We have many high quality kitchen knives. I am a hunter and fisherman and have always bought and used the highest quality knives for those purposes so I know a great a great knife made from a great steel when I use one. This Santoku is definitely a great knife the few times my wife has let me try it. She uses it almost exclusively these days! Thanks so much, Mr. Iwakara and Japanese Chef’s Knife!

    Superb Knife

    The knife is beautiful to look at and hold. The handle would suit either left or right hand and it is very light but with all the weight in the blade where you want it on one of these. It is razor sharp straight out of the box and superb value. It also arrived in 3 days. I would recommend this knife to anyone.
