People who see a deba for the first time often take it for a small cleaver, because it is thick, heavy for its length, and made to go through fish bones. Tojiro, a knife maker in Niigata, seems to agree with them. In its Japanese guide to specialty knives it describes the Western cleaver as a knife close to the Japanese deba. I wanted to know how close, so I compared the listed weights of both at one shop, and then looked at where the Chinese cleaver fits, since that is a third knife sharing the name.
If you only want my pick: for fish, the Sakai Takayuki Kasumitogi white steel deba 150mm, $114.99 and in stock when I checked on 8 October 2026. If the job is chopping through chicken and pork bones, a deba is the wrong knife and the cleaver further down is the right one.
What Tojiro says about each
Tojiro lists the cleaver among specialty knives. It calls it a knife close to the Japanese deba, a hatchet-like tool made for cutting meat together with the bone. The blade is very thick and heavy, and the wide face is used for pounding bones to break them and for flattening meat. Tojiro adds that it does not sell one in its own online shop.
Its guide to fish knives describes the deba as the basic knife for breaking down fish, with a thick and fairly heavy blade, and says it suits taking the head off and cutting bone. Sakai Ichimonji Mitsuhide, a knife shop in Sakai, gave the same reason when I read its deba page on 6 October: the blade is very thick so that the edge holds up against the hard bones and head of a fish.
So both knives are thick and both meet bone. The bone is different. Every Japanese description of the deba I have read names fish. The cleaver description names meat.
The weights at one shop
Hocho-Knife sells both, so I took the weights given in its listings on 8 October 2026.
The Sakai Takayuki Kasumitogi deba in white steel weighs 230g at 150mm, 320g at 180mm and 440g at 210mm. The prices were $114.99, $148.99 and $226.99.
The one knife the shop simply calls a cleaver is by Sugimoto, a Tokyo maker, in its all-steel carbon line. It has a 185mm blade and weighs 685g. The price was $251.99.
That is about three times the weight of the 150mm deba, and more than twice the 180mm deba, which has nearly the same blade length. Even the 210mm deba, a size Ichimonji suggests for large fish such as sea bream and yellowtail, is 245g lighter than the cleaver.
The edge is different too. The deba is sharpened on one side. The Sugimoto cleaver is listed as double-edged. A single-sided edge is good at running along a backbone and lifting a fillet, and that is work a cleaver is not built for.
The Chinese cleaver is a third knife
A lot of what is sold abroad as a cleaver is the Chinese kitchen knife, the wide rectangle that Chinese cooks use for nearly everything. Tojiro describes it separately. It says professional ones are classed by weight more than by length, and that the cook does almost all the work with this one knife, so it has to handle everything between bone-in meat and fine vegetable cutting.
Sugimoto sorts its Chinese knives by thickness. Its product index labels No. 1 as thin, No. 2 as medium thick and No. 3 as thick, and has a separate No. 22 marked extra thick, for cutting bone. Hocho-Knife carries the first three in white steel at one blade size, 220mm by 95mm, and the weights rise in step: 370g, 460g and 555g. The prices on 8 October were $304.99, $351.99 and $382.99.
So a thin Chinese knife is a slicing knife that happens to be tall. It is not a bone chopper, and at 370g it is still heavier than a 180mm deba.
The thick ones are more careful about bone than I expected. Ichimonji sells a thick Chinese knife of its own at 550g and describes it as a knife for vegetables, boneless meat and fish, heavy enough that simple bones can be cracked with the spine. It also says not to use it on frozen food. The bone work it describes is done with the back of the blade.
Which one to buy
For whole fish, buy the deba. It is the lightest of the three, it costs the least, and the single-sided edge is what makes filleting clean. At home, 150mm handles fish up to the size of a mackerel. I compared it with lighter fish knives in deba vs fillet knife.
For chopping through chicken backs, ribs and other meat bones, buy a heavy cleaver and keep the deba away. A 230g knife with a hard single-sided edge can chip when it is swung at bone it was not ground for. I should say that this last point is my reading of the weights and of what the makers say each knife is for. None of the sources states it as a rule.
If you only want to take a chicken apart at the joints, neither is needed, and the Japanese knife for that is in honesuki vs deba.
A thin Chinese knife is for someone who wants one tall blade for vegetables and boneless meat and likes the weight. It does not do the work of a deba or of a bone cleaver.
Left-handed buyers should check the deba before paying. The left-handed version of the same 150mm knife was $207.99 when I looked on 6 October, against $114.99 for the right-handed one. The cleaver and the Chinese knives are double-edged and work in either hand.
Three knives, checked on 8 October 2026
The deba: the Sakai Takayuki Kasumitogi white steel deba 150mm at $114.99. 230g, single-edged for the right hand, in stock. White steel is carbon steel and rusts if left wet.
The cleaver: the Sugimoto all-steel cleaver 185mm at $251.99. 685g, carbon steel, double-edged, in stock. The listing gives the weight and the steel and does not say what the knife is meant to cut, so the use I describe above rests on the weight and on what Tojiro says cleavers are for.
The thin Chinese knife: the Sugimoto white steel Chinese knife No. 1, 220mm by 95mm, at $304.99. 370g, double-edged, in stock. Also carbon steel.
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 four tracked links, all to Hocho-Knife: three knives, and a second link to the deba near the top. At about 10 percent, that is roughly 11 dollars for the deba, 25 dollars for the cleaver and 30 dollars for the Chinese knife. The knife I suggest for most readers is the one that pays me least. Tojiro is quoted here as a source, and this page does not link to any Tojiro product. My full affiliate disclosure is here.
