Kouhei-Shinmatsu ZDP-189 Petty Black 135mm (5.3") comes as the culmination of a decade’s worth of expertise gained through selling and working with knives on our part, and the knowledge and mastery of Japanese knife forging, passed on through generations within the Suncraft smithy.
Due to our continued and successful collaboration with Suncraft, we decided to honor the founders of the smithy by naming this line of knives after them: Kouhei (耕平) Kawashima, who started Suncraft more than 70 years ago, and his father, Shinmatsu (新松).
A petty knife is an essential piece of any knife collection, filling in when bigger, longer knives can be a bit awkward to use. This particular petty is a bit on the thicker side, so it will complement the thin Kouhei-Shinmatsu ZDP-189 Bunka very nicely. Aside from excelling at usual tasks, such as peeling, paring and other in-hand cutting, you can use it for some heavier work as well. Light butchering, poultry deboning and fish filleting are completely within its reach (🚨 Just keep in mind that it's still an extremely hard knife, so cutting through bones and joints is out of the question!). The pronounced “K-tip” proves very useful with fine, decorative work with vegetables and fruit, as well as with trimming and skinning, as it’s great for piercing through the skin.
ZDP-189 steel has stood the test of time as the ultimate kitchen knife steel and remains a favorite among professional chefs, as well as aspiring home cooks. Therefore, we felt it was appropriate that a hardcore duo—such as this Petty and Bunka—was forged out of the most hard-core (literally) steel! Coming in at 65-66 HRC on the Rockwell scale, these knives are easily one of the hardest knives we offer, so edge retention will be second to none.
Put this in an equation together with a black kuro-uchi finish, treated with subtle hammer dents, and a beautiful octagon rosewood handle, and you got yourself a winner!
This petty knife is basically a smaller version of the Kouhei-Shinmatsu ZDP-189 Bunka. Petty knives are intended for all those smaller tasks where larger knives are deemed unwieldy, on and off the cutting board. A must-have knife in every kitchen, it can be used for peeling, mincing, paring and decorating food.
This knife was forged out of ZDP-189 steel, which falls into the powder steel category. The ZDP-189 steel has gained a reputation as one of the most technologically advanced steels in Japanese knife making, due to its unique characteristics. The carbon (C) content is around 3%, meaning it can be treated to extreme hardness (65-66 HRC), which results in extended sharpness retention. ZDP-189 steel is also highly corrosion resistant due to its high chromium (Cr) content of 20%. Because of its composition, though, it can be hard to treat and forge, so it can only be trusted to the most experienced blacksmiths.

The technique used to laminate this blade is called san-mai. The core of the blade, which is made of harder (and subsequently more fragile) steel, is sandwiched between two layers of softer steel. This results in a blade that is more flexible, and therefore less prone to breakage and other outside factors.

It has a double bevel (symmetrical) blade.
→ Read more on Blade construction: Geometry.
The upper part of the blade has a kuro-uchi finish, which was treated with hammer blows, resulting in a dark and textured tsuchime look. The lower half is polished down to the hairline, which is the curvy line marking the border between the laminated part of the blade (jigane) and its core (hagane). The kanji on the blade reads “Kouhei-Shinmatsu” 耕平新松, paying homage to the founders of the Suncraft smithy.

Still doubting which type of Japanese knife should best fit your needs? We created a quick, 5-steps quiz to help you find the perfect knife based on your cooking skills and the type of food you prepare.
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
Ciao, ho acquistato questo coltello per tagliare la pasta che faccio in casa. Premetto che sono mancino per cui gran parte dei coltelli giapponesi faccio fatica a trovarli. Il coltello è piacevole ma non propriamente da mancini. Un saluto
Very special handle,nice!
I just received my Yoshida Hamono ZDP189 santoku and I am over the moon with it. It was a hefty purchase, but well worth it. I’m currently restoring my knife collection since my previous one was stolen. This is a wonderful addition to my new collection.
Nice wrapped and really safe, amazing knife as a Santoku I had bought and really comfortable to use for whole day prep in the professional kitchen.
I purchased a knife from this website, unfortunately the knife was not of my liking, they provided a return label for me, then Fedex lost the package and it was a mess, lots of calls and emails but sharpedgeshop was always professional and gave me a full refund, they always responded to my emails quick and were very professional.
During the Purchasing process and a year later when I wanted to have something repaired, the service has been outstanding. Prompt responses and working with me to find the right solution.
Beautiful blade and handle. Thanks Sharp Edge!
Will be buying from here again due to the fact that the customer service made me feel like no matter what I'd have everything I needed and be getting my money's worth. They care about your experience and also have brilliant products
Knife was bought as a gift and the receiver loves it. They were responsive when emailed a question and the knife arrived fairly quickly.
It was a pleasure to shop here, so much information and good advice to help you find what you are looking for, pair that with exceptional service and communication and you have a shop who is dedicated and passionate about what they do. Highly rated and thank you
I ordered a knife for a friend with custom engraving and the customer support went above and beyond to help make sure I received the product I asked for. They were quick, friendly, and considerate, and shipped the knife extremely quickly. When a part of the Saya was damaged during delivery I received a replacement (several just in case) the next day!
The knife itself looks great, is nice and sharp, and is exactly what I had hoped to order. Will definitely order again for myself.
I'm really satisfied with the quality of the knife. A great product. And the customer service was great. I have a very small thing to share and it’s not a complaint at all. The knife was a gift and overall the packing is okay. But the knife box was a little bit low quality and i hope that would be okay with lots of customers and if there is an option to buy a little bit higher quality box, it would be very nice. Thank you.
Prompt and reliable team at “Sharp Edge”. I received my item promptly and was well packaged. I had a query about the handle before I purchased this knife. The team at Sharp Edge actually went to the trouble of doing a test and gave me an answer in four days.(I asked them about the suitability of composite handles for sanitising in hot water). All Is good!
