The 4 Finest Deba Knives of 2023, Examined & Reviewed

Straight to the Level

When selecting a Deba knife, expertise degree and fish dimension are essential elements. With this in thoughts, we advocate the Kai Seki Magoroku Kinju ST Japanese Deba Knife 150mm as a flexible choose for inexperienced persons (and execs) alike, because of its hefty, sharp stainless-steel blade.

Like breaking down a hen, filleting an entire fish enables you to see the place that clear piece of meat comes from. And whereas it’s a messy enterprise—guts, gills, and scales galore—it’s additionally typically extra economical—plus, you should use the bones and head for dashi and different dishes. 

Whereas some people favor to make use of a flexible boning knife to swipe a filet off of a fish, once I was a prep prepare dinner at a restaurant, butchering complete fish was carried out with Deba knives. This stocky, Japanese knife may be very totally different from a boning knife with its thick backbone and single-beveled edge. However as Masaaki Saito, proprietor of Saito Knives in Brisbane, Australia, explains, that is what makes the Deba a really multi-purpose knife.

“The largest benefit of Deba knives over different European-style filleting knives is that every thing will be carried out with one knife,” he says. “It’s troublesome to chop bones or fins with a thin, versatile, filleting knife, as you will have a cleaver or scissors to work on any bony elements, whereas the sharp a part of Deba knife can simply trim the flesh off the bones and the thick heel can halve the top, lower the bones into items, and take away fins.” That mentioned, selecting and utilizing a Deba knife requires some analysis—and perhaps watching a number of YouTube movies on the best way to use them.

To assist get you began, we examined 10 knives by filleting fish huge and small, spoke to specialists, and even introduced our favorites to an area fishmonger to check out. In any case this testing, we discovered 4 choices for knowledgeable fish butchers and newbies alike. 

The Winners, at a Look

The largest, heaviest knife in our lineup, the Tojiro was additionally tremendous sharp because of its carbon metal blade. Its heft (it weighs a whopping 10.3 ounces) additionally helped it easily glide between the fillet and bones, making certain a fast, clear lower. It was additionally surprisingly well-balanced. 

The Assessments

  • Usability Assessments: All through testing, we famous how straightforward the blades had been to deal with, preserve, and clear. 

What We Discovered

Deba Knives Are Totally different Than Versatile Fillet Knives 

Severe Eats / Grace Kelly / Ashlee Redger


As Masaaki Saito, proprietor of Saito Knives, defined, not like boning or filet knives, Deba knives should not solely used to filet but in addition to chop by way of bone and clip off fins so the prepare dinner can use all elements of the fish. “Deba knives are designed for breaking down complete fish,” he says. “In Japanese delicacies, most elements of the fish are used to create totally different dishes. You may discover dishes like grilled snapper head, butterflied complete Alfonsino, or Grouper hot pot (with diced head, wings, and bones) served at top-end eating institutions. So cooks wanted heavy-duty knives to chop by way of laborious fish bones simply with out damaging the sting.” And heavy-duty they’re! Practically all the knives we examined had spines that had been fairly thick and heavy, with the Tojiro successful the prize for the thickest, heaviest knife with a 7-millimeter backbone and 10.3-ounce weight. This heft and bulk is intentional and, as Saito famous, helps break by way of bone and ensures fast, clear cuts.

Easy methods to Use a Deba Knife 

Severe Eats/Grace Kelly


Chopping fish with a Deba knife is barely totally different than doing it with a filleting knife. Whereas some filleting methods begin by merely making a slit close to the gills, the Deba methodology does this on both sides, however then additionally removes all the head. As soon as the top is eliminated, you possibly can run the knife from the again of the abdomen ahead to open it and clear out the heart (if this hasn’t already been carried out).

As soon as that’s carried out, use the knife to softly lower alongside the inside of the backbone and wipe it out. Then, begin filleting by operating the blade down from the stomach in the direction of the tail, flip the fish over, and run the blade (barely angled) alongside the highest of the fish from the tail to the top. Now, swipe the knife gently between the backbone bones and the flesh—it is best to hear a scraping sound the place the blade is slicing the fish away from the bones. Do the identical on the underside of the identical aspect, then separate the filet by slicing by way of the flesh close to the tail. Repeat on the opposite aspect. 

A Sturdy Grip Was a Should

Severe Eats/Grace Kelly


Filleting fish is a messy, slippery enterprise, so whereas a grippy deal with would possibly seem to be one thing of little significance, we discovered it extremely useful. A lot of the Deba knives we examined had tough wooden handles that made them simpler to grip. Nonetheless, the Kai Wasabi Deba Knife had a rounded, plastic deal with that received actually slippery throughout filleting, which isn’t ideally suited once you’re wielding a heavy-duty, sharp knife. Gattuso additionally discovered handles that narrowed barely in the direction of the bolster, like on the Sakai Takayuki Kasumitogi Deba 150mm, had been simpler to grip and management. 

Expertise Stage Mattered

In case you’re new to Deba knives, you may want a smaller, softer knife, which is much less more likely to chip and simpler to keep up and use. “For newbie customers, hybrid ones could also be simpler to keep up due to the straightforward upkeep and extra forgiving traits, whereas the white carbon metal ones can rust simply and chip simply, however have significantly better sharpness and edge retention when used correctly,” Saito says. He additionally suggests on the lookout for knives with shorter blades, 150 to 180 millimeters (round six to seven inches lengthy). In case you’re extra assured filleting fish, have used a Deba knife earlier than, and are used to Japanese-style blades, an extended, carbon steel blade could possibly be a sensible choice. 

Fish Dimension Was Additionally Vital

Severe Eats/Grace Kelly


In case you’re filleting sardines or different small fish, a giant, hefty Deba is likely to be tough to make use of with out mashing. Conversely, in the event you’re filleting a roughly 24-inch bluefish (like we did), a thicker, hefty blade could make fast work of eradicating the top, gutting, and filleting. Saito gave us a common thought of Deba to fish sizes: 

Fish Sort and Knife Size
Fish Sort Perfect Knife Size
Garfish, Blue Mackerel, Jack Mackerel, Herring  120mm or smaller
Small Snapper, Rainbow Trout, Flounder, Rock Cod, Alfonsino 150 to 180 millimeters 
Salmon, Ocean Trout, Massive Snapper, Mahi Mahi, Yellowtail Kingfish, Trevally, Sea Bass, Grouper  195 to 225 millimeters
Swordfish, small Tuna 240 millimeters and bigger

Our Favourite Knives Have been Balanced, Sharp, and Multipurpose

Severe Eats / Grace Kelly


Whereas many of the knives we examined had been extremely sharp out of the field and carried out properly, our favourite knives had been extra versatile by way of dimension and had a balanced blade and deal with. When it got here to the extra conventional fashion Deba with a carbon metal blade, we actually appreciated the Sakai Takayuki, which had a 150-millimeter-long blade (round six inches lengthy), a grippy wood deal with, and a balanced really feel. The hefty Tojiro was additionally nice, balancing weight with sharpness and agility. Each of those knives excelled at fileting fish huge and small. Whereas the white metal Okeya Deba was additionally fairly sharp, it was actually small and light-weight, with a five-inch-long blade and a mere 3.5-ounce weight—it’s most likely higher suited to filleting smaller fish and even mincing scallions or different tender greens. When it got here to hybrid knives, that’s, knives which can be made from stainless-steel and therefore softer, we additionally most popular mid-sized knives; amongst our favorites had been the kai Seki Magoroku Kinju ST Japanese Deba Knife and the Fujiwara Kanefusa FKM Series No.3 Deba, each of which had easy-to-grip handles, and balanced and sharp 6-inch blades; they tackled bigger fish as simply as they did small scup. 

The Standards: What to Search for in a Deba Knife 

Severe Eats / Grace Kelly


We advocate on the lookout for a flexible Deba knife with a blade that’s 150 to 180 millimeters (roughly six to seven inches) and has sufficient heft to chop by way of bone and shortly lower flesh away. It also needs to have a grippy deal with that gained’t get slippery or slick when moist.

In case you’re nervous about sharpening knives or have by no means used a Deba, a hybrid stainless-steel mannequin is likely to be the only option by way of upkeep (they’re additionally much less more likely to chip). In case you’re an previous hand at filleting fish, a high-carbon metal blade presents a refined edge and fast, biting cuts. And in the event you’re left-handed, be sure you select a knife that provides an choice to have the single-beveled edge switched to the left aspect (although this may increasingly should be carried out through particular request).
