A Western boning knife and a Japanese honesuki do the same job, taking meat off the bone, and they go about it in opposite ways. One bends and the other does not. I read how two knife shops in Sakai describe the honesuki to Japanese customers, compared that with the published specifications of a German boning knife, and then checked how the honesuki sold on an export site are ground, because that last point decides whether a left-handed cook can use one.
If you only want my pick: the Sakai Takayuki INOX PRO honesuki 150mm, $113.99 and in stock when I checked on 20 October 2026. It is one of the few listed as double-edged for either hand. The reasons are below.
What Japanese shops say the honesuki is
Sakai Ichimonji Mitsuhide describes the honesuki as a knife used mainly to cut meat such as beef away from the bone. It says the blade is thick and is often sharpened on one side, so the edge does not chip easily when it touches bone. It adds that the knife is lighter and handier than a deba, so some people use it to break down fish.
Jikko, another Sakai shop, says nearly the same thing: a knife for cutting meat off the bone, thicker than a gyuto and made so that it resists chipping, and also handy for fish.
Two things stand out if you have read about this knife in English. The first is that neither shop presents it as a chicken knife. Ichimonji names beef. The knife it connects with chicken is the garasuki, which it describes as the knife for cutting through the cartilage and joints of poultry. Jikko describes the garasuki simply as the same shape in a larger size, and I put the two side by side in honesuki vs garasuki. Plenty of people do use a honesuki on chicken, and it suits the job, but the Japanese descriptions are broader than that.
The second is the grind. Ichimonji groups the honesuki with Western-style knives, the family that includes the gyuto and the petty, and then notes that the honesuki and the garasuki are exceptions inside that family because they have a single-edged shape.
What a Western boning knife is
For comparison I used the Zwilling Pro 5.5 inch flexible boning knife, because Zwilling publishes its numbers. Zwilling describes it as a long, thin, flexible blade for precise trimming when separating meat from bones and joints. The listed blade thickness is 0.04 inches, which is about 1mm, the hardness is 55 to 58 HRC, the weight is 0.33 pounds, about 150g, and the price on the United States site was $129.99 on 5 October 2026.
The idea is that the blade bends to follow the bone. You keep the edge against the bone and let the steel flex around the curve.
How the two differ in use
The honesuki does not bend. It has a straight edge, a stiff triangular blade and a sharp point. The point goes into a joint, and the stiff blade can be pushed along the bone without wandering. Because the blade is thick, the edge survives contact with bone that would roll or chip a thin knife.
That does not mean it chops bone. Both Sakai shops say it resists chipping, and neither says it is for cutting through bone. Ichimonji describes the deba as the heavy knife whose weight is used to chop through fish bones and heads, and I compared the two in honesuki vs deba. I listed the causes of chips that Japanese makers warn about in my Japanese knife chipped.
Going by those descriptions, a flexible boning knife is easier on curved bones and for taking skin or silverskin off in a thin layer. A honesuki is quicker on joints, and its stiffness makes it more predictable for someone who is used to Japanese knives. The honesuki also works as a sturdy small knife on a board, which a narrow flexible blade does not do well.
The grind, and why it matters if you are left-handed
On 5 October 2026 I went through the honesuki listed on Hocho-Knife. There were 54 single-knife listings and 46 were in stock. Of the 22 listings that state the edge in their product details, 16 are single-edged, and two of those 16 are left-handed versions. Three more are double-edged with an uneven grind that the shop says suits right-handed cooks better. Only three are described as double-edged for both left and right hands.
So the usual honesuki is a right-handed knife. If you are left-handed and buy one without checking, the blade will steer the wrong way against the bone. The left-handed versions I found were in one carbon steel line and were out of stock that day. The practical answer is one of the three double-edged ones. I explained how a single-edged blade behaves in single bevel vs double bevel.
A single-edged honesuki is also sharpened differently, mostly on one face.
Square or round
You will see two shapes. Jikko calls the one with a heel the square or eastern type, and the one with no heel, where the edge runs in a curve into the handle, the round or western type. Listings in English call the second one sakimaru honesuki or honesuki maru. Jikko mentions fish only for the square type. I have not found a Japanese source that says one is better for chicken than the other, so I would choose on whether you want a heel to work with.
Which one to buy
Buy a Western flexible boning knife if you mostly trim large cuts, take skin off fish, or follow long curved bones, and you like the feel of a blade that gives.
Buy a honesuki if you break down whole chickens, take apart joints, or want one stiff small knife that can touch bone without damage. Check the grind before you pay.
If you already own a petty knife of 150mm, be aware that a honesuki is a different thing. A petty is thin and will chip on a joint. I compared the petty with the Western paring knife in petty knife vs paring knife.
Three honesuki, checked on 5 October 2026
For most people, and for left-handed cooks: the Sakai Takayuki INOX PRO honesuki 150mm at $113.99. AUS8A stainless with a stainless handle, 133g, listed as double-edged for both hands, in stock.
The least expensive stainless one I would consider: the Sabun MV stainless honesuki 135mm at $87.99. 150g, single-edged, so for the right hand, in stock.
The classic pattern: the Misono MV stainless honesuki 145mm at $132.99, the price on 21 October 2026. 180g with a pakkawood handle, single-edged, in stock. The round version of the same knife is 170g.
All three are stainless. Raw meat and a knife that gets rinsed often are a poor match for carbon steel unless you dry it every time, which I covered in patina or rust.
If you are left-handed, or want to see every honesuki the shop lists side by side, I counted them in best honesuki knife. Most are single-edged for a right hand.
Disclosure
I have four approved affiliate partnerships: two with knife retailers, Hocho-Knife and SharpEdge, and two with Japanese language-learning companies unrelated to knives. This page carries three tracked links, all to Hocho-Knife: two knives, and a second link to the INOX PRO honesuki near the top. At about 10 percent, that is roughly 11 dollars for the INOX PRO and 9 dollars for the Sabun. The Misono link is a plain one. Hocho-Knife leaves Misono out of its commission program, so I earn nothing if you buy that knife. I earn nothing from Zwilling, and this page does not link to it. My full affiliate disclosure is here.
