Like all Moritaka Supreme knives, this kurouchi-finished santoku sports a core of very hard Aogami Super steel which can take an incredibly acute and refined edge. This steel is also slightly less reactive than other carbon steels due to the high alloy content.

Moritaka Hamono is one of the oldest knife manufacturers we carry on our site and centuries of crafting hand forged blades have culminated in these wonderful knives. 50/50 convex grinds provide great ingredient separation and the high level of fit and finish on these knives belies the extremely aggressive pricing for such a premium product. We are thrilled to be the only US distributor of these knives which are truly a piece of Japanese blade making history and an exceptional value. The video on the page is not current.

      Pleasant surprise, November 23, 2019
    Posted By: Kirk S. - verified customer

    In use for the past 2 weeks. I'm extremely happy with the purchase. Surprisingly light compared to my other knives made from VG10. Fantasticly sharp edge with good retension. I strop my knives every week on 8k grit and use a ceramic rod during use. No complaints here. Also note the factory edge needs more time on a polishing stone to finish the edge. The only thing I wish was different was the possibility of getting the moritka custom handle. But at the time of purchase there was no santoku's. I would say the price is definitely worth the knife. I also highly reccomend getting the CKTG saya. Something about having an edge guard on a japanese knife just doesn't jive with me.

    I purchased this knife from CKTG after a long window shopping experience and many questions on the CKTG Forums. This knife is truly a diamond-in-the-rough!When it arrived it needed a little attention with a small file and some sandpaper to relieve/round the spine and choil. Ten minutes of fine tuning and you'll have an exceptional knife.Handle:Great fit and finish on the handle.Tang to handle is fit well and sealed completely (appears to be Water Putty).No gaps or steps between the buffalo horn ferrule and the Ho wood portion of the handle. Blade:When the knife arrived I didn't care for the laquer that was applied to the KU finish, so I set out to remove it with acetone. The acetone removed a portion of the KU finish... so I removed the rest of it. The AS steel in this blade is extremely hard @ 64/65 HRC.It will take a very acute angle - current;y at 10*Performance:I haven't met an item yet that this blade didn't perform well with.I have cut just about every veg available at my local market, and several types of meat. It isn't laser thin behind the edge, but it glides right through product.*If you have ever used a ceramic knife to cut produce with... it gives that type of feedback, or lack of; from being so scary sharp!This was my first JK and obviously my first Moritaka, BUT... it won't be my last!I am extremely pleased with the performance of the knife in general, and from the customer service at CKTG!

    This is my third moritaka, probably won't ever buy anything else but moritaka ever again. Great craftsmanship, reasonably sharp out of the box, but holds a nasty edge with s little work. Super light and easy to use. Definitely highly recommend this line of knives.

    received this knife about 2 weeks ago and really love it, the edge has stayed sharp with lots of use in a professional kitchen. Amazingly light weight and comfortable my first Aogami Super Steel knife. Only complaint is that the appearance of the knife(Kurouchi finish) comes off after wiping it off and cleaning consistently.

    this is by far the nicest santoku i have seen but i am partial to agomi super steel. i like the fact that a stainless tang was forged to the blade to prevent rusting up in the handle. the kurouchi finish does not bother me in the least. the right handed handle has a slight ridge in the D. very nice overall.

    This is an excellent deal on a fantastic knife. The kurouchi finish is rough, but delightfully so, if its your taste. The rosewood handle is attractive, lightweight and still well balanced. The blade itself is razor sharp out of the box, and should stay so, as is the nature of Aogami Super steel. I have yet to sharpen, however each knife comes with one free sharpening through moritaka, or should sharpen up easily on your own stones. Overall, this knife is a workhorse with lots of character and a purchase that will not be regretted.

    This is a great deal on a hand made aogami super knife. The coating on mine was a bit sloppy, but aogami super is very appropriately named. I work in a sushi bar 5-6 days a week and was starting to get a bit of soreness/stiffness in the top knuckle of the thumb of my knife hand. I was using a fancy, heavy, modern damascus santoku for my veggie and roll cutting duties and after switching to the Moritaka my thumb is thanking me. This think is astoundingly light! It's also scary sharp, and like all straight carbon steel it's (in my opinion) easier to sharpen than soligen, molybdenum, or VG10 steel. The handle is great too. Similar to Shuns D shaped, but with a more pronounced bump. A feather weight lightsaber.

    This knife is a very light weight knife. I think that even MAC knives seem to feel heftier. It's wicked sharp though and the images online don't do the knife justice. Well worth the money if you want a feather with a razor's edge.
