#TLDR
The santoku knife excels at fine, precise slicing; the chef knife handles a wider range of kitchen tasks. For most UK home cooks buying their first quality knife, an 8-inch chef knife is the more versatile, practical starting point — and the DWELLUXE AristoBlade 8-inch Chef Knife delivers that performance at an accessible price with free UK delivery.
What Is a Santoku Knife?
The word santoku translates from Japanese as "three virtues" — a reference to the three tasks it was designed for: slicing, dicing, and mincing. Developed in post-war Japan as a home-cook-friendly adaptation of traditional Japanese blades, the santoku knife typically measures between 5 and 7 inches in length, with a flat cutting edge and a distinctive "sheep's foot" tip that curves steeply down to the edge rather than tapering to a point.
Most santoku knives also feature a Granton edge: a series of hollow dimples along the blade that create small air pockets between the steel and the food. This reduces drag and prevents thin slices from sticking to the blade — particularly useful when cutting soft ingredients like cucumber, smoked salmon, or cooked potato.
The santoku is lighter than a typical Western chef knife and distributes its weight more evenly along the blade, giving it a balanced, almost neutral feel in the hand. Serious Eats recommends an ideal santoku weight of six to seven ounces — anything heavier and the knife begins to lose its characteristic precision.
What Is a Chef Knife?
The chef knife — also called the cook's knife or Western chef's knife — is the backbone of European and American professional kitchens. A standard chef knife measures 8 to 10 inches in length, with a broad, curved blade that rises from the heel to the spine and tapers to a pointed tip. That curve is the defining design feature: it allows the chef knife to rock back and forth on a chopping board, keeping the tip in contact with the surface while the heel rises and falls in a continuous motion.
Chef knives are typically heavier than santoku knives, with weight concentrated toward the heel and bolster. This forward weight helps drive the blade through denser ingredients — large butternut squash, thick cuts of beef, dense root vegetables — with less effort from the cook.
In the UK, the chef knife has been the default choice for home cooks and professional kitchens alike for generations. Most culinary training in Britain uses chef knife technique as its baseline, which has practical implications for beginner cooks building their skills.
Key Differences: Santoku vs Chef Knife
| Feature | Santoku Knife | Chef Knife |
|---|---|---|
| Blade length | 5–7 inches | 8–10 inches |
| Blade tip | Sheep's foot (curved downward) | Pointed tip |
| Cutting edge | Flat or minimal curve | Pronounced curved belly |
| Edge angle | 10–15° per side | 15–20° per side |
| Weight | Lighter (170–200g typical) | Heavier (220–280g typical) |
| Balance | Neutral / blade-balanced | Heel-weighted |
| Granton edge | Common | Less common |
| Primary motion | Up-and-down chopping | Rocking |
| Best for | Slicing, dicing, mincing | Slicing, chopping, rocking cuts |
Cutting Technique: How Each Knife Moves
This is where the two knives diverge most significantly, and where choosing the wrong style for your technique can feel frustrating.
The santoku knife suits a straight up-and-down chopping motion. Because its blade is nearly flat, there is little belly to rock on; instead, the cook lifts the blade and brings it straight down. This produces clean, even cuts and works superbly for julienning vegetables, slicing herbs, and fine-dicing onions.
The chef knife rewards a rocking motion. The curved belly stays in contact with the board as the handle rises and falls, creating a fluid, efficient rhythm. This technique — sometimes called the "pinch grip rock" — is what most UK cookery teachers and culinary schools teach as the foundation of knife skills. For home cooks learning proper technique from scratch, the chef knife's rocking motion is generally easier to master.
If you have ever watched a professional chef mince a pile of herbs in seconds, the motion you observed was almost certainly a rocking chef knife, not a santoku.
Which Tasks Does Each Knife Handle Better?
Santoku knife strengths
- Precision slicing: Paper-thin cuts of fish, meat, and vegetables
- Repetitive dicing: Fine dicing of onions, garlic, shallots
- Soft ingredients: Tomatoes, soft cheese, cooked proteins — the Granton edge prevents sticking
- Smaller hands or shorter arm reach: The shorter blade is easier to manoeuvre for some cooks
Chef knife strengths
- Large vegetables: Butternut squash, cabbage, celeriac — the length and weight drive through dense produce
- Meat prep: Breaking down a chicken, trimming a joint, slicing a roast
- Herb mincing: The rocking motion processes large quantities of herbs quickly
- Versatility across ingredients: One knife handles the full range of daily kitchen tasks
- Bread scoring and general utility: The pointed tip opens packaging, scores pastry, and transfers ingredients from board to pan
For a UK home cook preparing roast dinners, weeknight stir-fries, curries, pasta dishes, and Sunday joints, the chef knife covers every scenario. The santoku excels within a narrower range, however brilliant it is within that range.
Blade Angle and Sharpness
The santoku's sharper edge angle — typically 10 to 15 degrees per side, compared to 15 to 20 degrees for a Western chef knife — produces a finer cutting edge. Japanese Knife Lab notes that Japanese-style blades (which includes the santoku) typically achieve HRC hardness ratings of 60 to 67, compared to 54 to 58 for German-style chef knives.
In practical terms, this means the santoku holds a razor edge longer, but that edge is more brittle and more sensitive to lateral stress. Use a santoku to split a hard squash or pry apart a shell and the edge chips. Use a chef knife for the same task and the slightly softer, more obtuse edge flexes and recovers.
For home cooks who sharpen infrequently — which describes most of us — the chef knife's more forgiving edge is a practical advantage. Its wider angle is also easier to restore on a standard pull-through sharpener or a basic whetstone, without specialist Japanese sharpening equipment.
Weight and Balance
Serious Eats' testing found that santoku knives perform best in the six to seven ounce range, with a neutral balance point somewhere around the bolster. Chef knives tend to run heavier — eight to ten ounces — with the balance point sitting slightly toward the heel.
Neither is objectively better; the preference is personal. Cooks who find a heavy blade tiring during long prep sessions often prefer the santoku's lighter feel. Cooks who want the knife to do more of the work through its own momentum tend to prefer the chef knife's weight.
That said, modern chef knives — particularly those made from high-carbon stainless steel with thinner blades — have narrowed this weight gap considerably. A well-constructed 8-inch chef knife from a quality brand can feel almost as nimble as a santoku, while retaining all the versatility advantages.
Which Should a UK Home Cook Buy First?
If you are equipping a kitchen for the first time or replacing a worn-out block-set chef knife, the 8-inch chef knife is the right starting point for the majority of UK home cooks. Here is why.
1. Versatility. A single 8-inch chef knife handles 90% of daily kitchen prep: chopping onions, slicing chicken breasts, breaking down vegetables, mincing herbs, and portioning fish. A santoku handles a narrower range with higher precision, but precision is less critical on a Tuesday night when you need dinner on the table.
2. UK cooking traditions. British home cooking — roasts, stews, curries, pies, bakes — leans heavily on technique that the chef knife was designed for. The rocking cut and the pointed tip suit the actual tasks most UK home cooks perform most often.
3. Easier to sharpen and maintain. The chef knife's edge geometry works with standard pull-through sharpeners, ceramic rods, and beginner whetstones. Santoku edges are more delicate and repay proper Japanese sharpening technique — an investment in time and skill that not every home cook wants to make.
4. Longer reach. The 8-inch blade handles large ingredients that a 5 to 7-inch santoku cannot. Slicing a full roast, breaking down a joint, or working through a large cabbage is simply easier with a longer blade.
5. First knife, not only knife. Once you have a quality chef knife as your workhorse, adding a santoku for precision work becomes a natural second purchase. Starting with the santoku and adding a chef knife later is a less efficient order.
