Morado Petty Kuro-uchi 150mm (5.9")
Best To Use
(click on icons for more knives)
Morado Petty Kuro-uchi 150mm (5.9") is basically a smaller version of a gyuto knife (Chef's knife). Petty knives are intended for all those smaller tasks where larger knives are deemed unwieldy, both on and off the cutting board. A must-have knife in every kitchen, it can be used for peeling, mincing, paring and decorating food.
The core of this knife is Hitachi's Super Blue Steel (Aogami Super), which is the very top quality of traditional Japanese steels. The Kuro-uchi (black) patina on the upper part of the knife gives it a unique and rustic appearance. This knife was heat-treated to around 63 HRC. It is a very hard steel, meaning that it will retain a super-fine sharpness for a long time. In addition, due to the high carbon content (1.4-1.5%), the knife is very easy to sharpen. Among the high carbon steels, Aogami Super is also the least sensitive to rust. It also contains 0.4% vanadium as an admixture for micronized metal grains, which gives the steel more toughness. Aogami Super is rated as the most advanced carbon steel. The outer layers are of softer, stainless steel, giving the knife extra rust protection.
Kuro-uchi finish, the unprocessed (black) part on the top side of the blade has already developed a dark patina, which protects the blade and gives it a traditional Japanese look. The knife bears visible impressions of the hand-forging process (round hammer dents on the blade), which gives it a beautiful finish and also prevents food from sticking to the blade.
The handle (traditional Japanese Wa) is oval and smooth, with no discernible transition between the rosewood
and maple wood. It’s suitable for both left- and right-handed users.
In Japanese the word Harukaze means "a windy spring". This smithy is famous for the best quality traditional steel used for the core of the blade, coupled with stainless outer layers and elegant wooden handles.

Great customer service, very helpful and eager to fulfil your needs, along with their great passion and love for what they do.
Amazing quality knives, with a great delivery service.
5 Stars in every aspects!!!
I am located in the US. I bought a Yoshida Hamono HAP 40 wide gyuto. The knife performs extremely well. The transaction went smoothly. It was a pleasure to do business with this company.
The knife arrived damaged through the post . I contacted Sharp Edge and Urban was very helpful and sent me a new knife , without any complications. I can't recommend them enough .
very fast delivery
As with all new shops I buy from I like to be careful! Check them out and just be careful even more so when buying something expensive.
So I did my research but decided to side with caution and pay via paypal, I should not have worried !!!
Bought and paid for my knife on Friday morning and it was delivered to the UK on the Monday, how good is that.
The knife is very nice and also one I had been looking for for a while si I am very happy, next time I will pay by bank transfer as I have a Euro balance which helps.
Very nice to deal with and I have been through Slovenia on many occasions so nice to hear they are going Global.
At last i find my knife… yeah. Great product and work already with it. Worth every Cent. 🤩
Very good sorted Shop with beautyful things and gifts. What ever you need for your japanese
knife expirience…. they have it. 😎
Also the delivery was professional, correct and safe. And on time (3 days to Germany). Always
getting delivering status and informations. Perfect!
Great Job and thank you so much. Domo arigato gozaimasu!
Thanks for what you are doing, one of a few e-shops in EU with japanese knives.
Fast delivery (on third day it was in Prague/Czech republic)
High level product, delibera on time, very nice and funny packaging!! 😆 Thank you so much!
Un cuchillo precioso, me encanta el diseño y su agarre. No le doy 5 estrellas por que lo tuve que afilar nada más recibirlo, al afilado de fábrica le daría tan solo un 5/10. creo que un cuchillo como este debería llegar afilado al cliente al máximo de su capacidad.
From the knives that I’ve purchase to the ones I’m currently waiting for are phenomenal. My current daily driver is a Hokiyama 240 wa gyuto with your King 1000 Big Mama stone. Sat there laughing at the description. Currently sold my Sous Chef to get the current knife I’m using, thanks to Urban for helping me out. Looking forward to doing more business with SharpEdge.
I bought HAP-40 santoku Black tokyo night for my husband birthday 🥳!
Was absolutely successful 🙏🏻

Great service, delivered internationally as arranged. Would definitely do business with Sharp Edge again!
Yesterday I cooked a Chinese meal for a couple of friends: a main mie dish and verious side dishes. Preparing all the vegetables and meat with this Santoku was a joy: effiortless and precise cutting. Probably this inspired me to be as precise in the cooking itself, because we all agreed that it was the best version of this recipe I ever made.
This is the second knife I purchased from SharpEdges. The first one - a Yoshida kiritsuke 135 mm black HAP-40 is also very good. I like the (almost) minimalistic simple but (almost) perfect finish of these Yoshida blades and handle.
All in all I regret that I did not discover your shop earlier. I already have a nice collection of other Japanese knives with different steels and shapes. No need on the short term for replacements or filling some gap. But who knows?
Delivery by DHL Express from Ljubljana to the Netherlands is okay but not perfect. Oh well. Who cares?
Thanks guys for the good service, the European sense of humour and the - especially that - great products.
Well received and everything in great condition, great knife bag and the blade covers fits perfectly... Thanks
