Turn over any of Studio William’s forks or spoons, and you’ll spot a small stamp on the back. It reads 18/10. Most people glance at it and move on. But those numbers are quietly telling you everything about the quality of what you’re holding. Once you understand what that means, and what “cutlery” really means in terms of material quality, you’ll never look at a piece of cutlery the same way again.
Here’s something we see all the time at Studio William. Someone picks up one of our forks for the first time and pauses. The weight feels right. The balance sits naturally between their fingers. The finish reflects the light softly, creating a feeling of warmth rather than a sharp metallic sensation.
That reaction starts with the material used to make cutlery, steel. Once you understand the reason we choose 18/10 stainless steel to bring our designs to life, you’ll know exactly what makes our cutlery the most award winning cutlery brand in the world.
What Do the Numbers on Cutlery Actually Mean?
Most people assume 18/10 is a product code or a model number. It’s not. It’s a shorthand for the composition of the steel alloy, and it has an interesting history.
These consumer-facing names were actually invented in the United States in the early 1980s. The American flatware industry needed a simple way to help shoppers understand why one set of cutlery cost more than another, and why the finishes looked so different side by side. So they created a naming system based on the two most important components in the steel. These are not technical grades you can order from a steel mill. They’re a consumer-friendly translation of what’s inside the metal.
Chromium, Nickel, and Why the Ratio Matters
Stainless steel is made by adding two key elements to regular carbon steel: chromium and nickel.
Chromium creates an invisible oxide layer across the metal’s surface. This film is what makes stainless steel “stainless.” It shields against rust, corrosion, and food acids. More chromium means more protection.
Nickel is where the magic happens. It produces that smooth, silvery lustre, makes the steel tougher and more corrosion-resistant, and makes it considerably easier to polish during manufacturing. Nickel is also more expensive than chromium, which is a large part of why premium cutlery costs what it does.
What Does 18/10 Mean on Cutlery?
The first number tells you the percentage of chromium. The second tells you the percentage of nickel. So 18/10 stainless steel contains 18% chromium and 10% nickel, with the remaining balance being iron and trace elements like manganese and carbon.
Simple enough. But the implications for how your cutlery looks, feels, and lasts are immense.
Stainless Steel Cutlery Grades Explained
There are four grades you’ll come across when shopping for cutlery. We work with these steels every day, so let us walk you through what each one actually is, how it’s made, and what it’s really called when a manufacturer places an order at the steel mill.
18/10 Stainless Steel: The Premium Standard
At the mill, this is known as Grade 304 stainless steel. It contains 18% chromium and between 8% and 10% nickel.
Forks and spoons are typically cold-forged from Grade 304. The nickel makes the steel easier to work with in production and far easier to polish to a true mirror finish. It also allows factories to press detailed decoration into handle surfaces, because the nickel makes the steel slightly softer and more formable under pressure.
According to the British Stainless Steel Association, Grade 304 accounts for roughly two-thirds of all global stainless steel production. It’s an exceptionally versatile, durable material.
18/8 Stainless Steel: Is It Any Different?
Here’s an insider fact that surprises most people. 18/8 and 18/10 are, in practice, the same steel. Both are Grade 304. When a manufacturer orders 304 from a mill, the nickel content will fall somewhere between 8% and 10%. There is no separate “18/8 shipment” and “18/10 shipment.” The naming distinction dates back to that 1980s marketing system.
18/0 Stainless Steel: The Price Conscious Option
The mill name is Grade 430 stainless steel. With 18% chromium but with zero nickel, 18/0 is the alternative grade of stainless to 18/10. If fully polished to remove raw material, it still resists rust to a high level thanks to the chromium, but without nickel, it has a very slight grey colour compared to 18/10. With high-end manufacturing polishing, however, it looks almost indistinguishable from 18/10. The high-quality manufacturing production is the most important factor in making 18/0 steel suitable for use as cutlery.
That’s an important point worth repeating. The steel itself is not inferior. What matters is the effort a manufacturer puts into finishing it. You’ll find poor-quality manufactured 18/0 cutlery in canteens, cafeterias, student halls, and budget sets. It serves a purpose, and it’s affordable and functional, but it won’t hold up to years of daily use the way 18/10 and high-quality production 18/0 cutlery will.
One practical difference: 18/0 is attracted to magnets, while 18/10 is not. If a fridge magnet sticks to your fork, you know it is 18/0 and there’s no nickel in the alloy.
13/0 Stainless Steel: Why Your Knife Blade Is a Different Metal
This surprises even experienced home cooks. In both 18/10 and 18/0 cutlery sets, the knife blades are always made from a completely different steel. Why? Both 18/10 and 18/0 are too soft to maintain a sharp cutting edge for a long period of time.
Table and side knives are hot-forged (rather than cold-forged) from Grade 420 stainless steel with higher carbon content to retain that cutting edge. After final manufacturing, every knife must be heat-treated (tempered) to a hardness between 48 and 52 HRC on the Rockwell scale. The knife handle is typically 18/10, but the blade itself needs that harder, lower-chromium steel to hold its edge.
Quick Comparison: Stainless Steel Cutlery Grades
| Grade | Chromium | Nickel | Shine | Corrosion Resistance | Durability | Typical Use |
|---|---|---|---|---|---|---|
| 18/10 and 18/8 | 18% | 10% | High mirror polish is possible | Excellent | Very high | Premium home, fine dining, hotels |
| 18/0 | 18% | 0% | Usually low mirror finish. High mirror polish is also possible | Good to excellent | Moderate to very high | Everyday use, hospitality, hotels and restaurants |
| 13/0 | 13% | 0% | High mirror polish is possible | If fully hardened, excellent | High when hardness is 48 to 52 HRC | All table and side knives |
Does Stainless Steel Cutlery Rust?
Stainless steel cutlery is rust-resistant, not rust-proof. Longer exposure to sodium (salt) and lemon juice (acidity) will cause rusting issues for cutlery. It is always important to follow the manufacturer’s recommended care of cutlery guidelines when you purchase cutlery. Especially when dishwasher where acid and heat can corrode even the highest quality cutlery.
Is Stainless Steel Cutlery Safe?
Completely. 18/10, 18/0, and 13/0 stainless steels are inert materials and the safest materials for food contact (in accordance with international food safety guidelines such as EU Regulation (EC) No 1935/2004), trusted in kitchens, hospitals, and food processing plants for well over a century.
Nickel Sensitivity: What You Should Know
A small number of people are sensitive to nickel, which usually shows up as a skin reaction from prolonged contact with nickel-containing jewellery. The nickel in 18/10 cutlery is locked within the alloy, and the amount that transfers during eating is well within safety limits set by the European Food Safety Authority. If you do have a confirmed nickel allergy, 18/0 is actually the best choice for the cutlery.
Food Safety and Non-Reactivity
18/10 stainless steel does not react with acidic, alkaline, or salty foods. It won’t leach chemicals, change the taste of your meal, or degrade with heat. This is precisely why it remains the go-to for professional kitchens, surgical instruments, and commercial food processing. The European Commission’s regulations on food contact materials specifically recognise stainless steel as safe for prolonged use at high temperatures.
Is 18/10 Stainless Steel Cutlery Dishwasher Safe?
Yes, 18/10, 18/8, 18/0, and 13/0 stainless steels are fully dishwasher safe, provided they are manufactured to good standards.
A few practical tips: don’t let pieces sit in the machine after the cycle ends, because lingering moisture can leave water marks. Avoid running silver-plated and stainless steel items together, as this can trigger a reaction between the metals. And place cutlery handles down so the eating surfaces get a thorough clean.
The Four Families of Stainless Steel
The grades used in cutlery represent just one corner of the stainless steel world. There are many types, grouped into four main families. Understanding where cutlery steels fit helps explain why specific grades are chosen for specific purposes.
Austenitic (300 and 200 Series) is the most common family. Non-magnetic, highly corrosion-resistant, and easy to form. Grade 304 (the steel behind all 18/8 and 18/10 cutlery) belongs here, alongside Grade 316, the marine-grade variant.
Ferritic (400 Series) steels are magnetic, with high chromium but no nickel. Grade 430 (behind 18/0 cutlery) sits in this family. Also found in automotive trim and kitchen appliances.
Martensitic (400 and 500 Series) steels are magnetic and heat-treatable to achieve high hardness. Grade 420 belongs here, which is why it works so well for knife blades and surgical instruments.
Duplex (2000 Series) steels blend austenitic and ferritic structures in roughly equal measure for superior strength. Used in chemical processing and marine engineering. You won’t find duplex in your cutlery drawer, but it shows just how specialised this world really is.
How to Tell the Quality of Cutlery Before You Buy
You don’t need a metallurgy degree to spot good cutlery. Three simple checks will tell you most of what you need to know, and you can do all of them in a shop.
The Weight Test
Pick up a single fork. Good 18/10 cutlery has a noticeable heft: solid and balanced without being heavy. If it feels flimsy or bends easily between your fingers, you’re looking at a thinner gauge or a lower grade. A lack of weight almost always signals a compromise.
The Magnet Test
Bring a small magnet along. Hold it against a fork or spoon (not the knife blade, since all blades are Grade 420 and will always be magnetic). If the magnet grips firmly, the cutlery is 18/0. If it doesn’t stick, you’re looking at 18/8 or 18/10. A very faint pull on 18/10 is normal and caused by the cold-forging process.
Check the Stamp
Turn the fork over. Premium cutlery fork and spoon will have “18/10” or “18-10” stamped on the back. If there’s no stamp and no mention of steel grade in the listing, that silence tells you something. Good brands are proud to declare their steel grade.
Why Studio William Uses 18/10 Stainless Steel Across Every Range
Every Studio William collection, from the organic curves of Olive to the architectural geometry of Okina and the nature-inspired silhouettes of Tilia, is crafted exclusively from 18/10 stainless steel. We don’t make an “everyday” range in a lesser grade. William has always believed that the material must be worthy of the design.
Grade 304 gives William the properties he needs to be able to design cutlery with creativity and quality. The nickel content allows fine detail to be pressed into handle surfaces. The alloy holds both mirror and satin finishes through years of daily use. And the weight and balance feel exactly right, whether you’re eating breakfast alone or hosting twelve for Christmas.
This is also why Studio William supplies British Airways First Class, Etihad Airways, 5 star hotels and Michelin-starred restaurants all over the world. At that level, anything less than Grade 304 simply isn’t considered. With every range staying in continuous production, you can begin with a 24-piece set today and add matching pieces years later, knowing the steel, finish, and feel will be identical.
Frequently Asked Questions
What does 18/10 mean on cutlery?
It refers to the composition of the steel alloy: 18% chromium for rust resistance and 10% nickel for shine and durability. This is the highest standard grade in consumer cutlery, known in the industry as Grade 304 stainless steel.
Is 18/10 better than 18/0 stainless steel for cutlery?
18/10 offers some inherent advantages: the nickel content provides natural corrosion resistance and makes it easier to achieve a mirror polish during production. However, a well-manufactured 18/0 set with high-quality polishing can look and perform beautifully for years. The most important factor is always the quality of manufacture. A premium 18/0 set made with care will outperform a cheaply made 18/10 set every time.
Is there a real difference between 18/8 and 18/10 stainless steel?
Functionally, very little. Both are classified as Grade 304 stainless steel, and most 304 produced for the flatware industry contains between 8% and 10% nickel. The naming distinction is a legacy of 1980s American marketing, though brands that specify 18/10 tend to demonstrate a broader commitment to quality.
Does 18/10 stainless steel cutlery rust?
Under normal use, no. 18/10 is highly resistant to rust and corrosion. That said, prolonged contact with salt, bleach, or standing water can cause pitting or surface staining over time. Rinsing after contact with salty or acidic foods, and unloading the dishwasher promptly, will prevent most issues.
Is stainless steel cutlery safe to eat with?
Yes. 18/10 stainless steel is non-reactive, which means it won’t leach chemicals or change the flavour of your food. It meets European Food Safety Authority guidelines for food contact materials and remains the standard across professional kitchens, hospitals, and food processing facilities worldwide.
Why are knife blades made from a different steel than forks and spoons?
Forks and spoons are cold-forged from Grade 304 (18/10), which is soft enough to shape and polish beautifully. Knife blades need to be much harder to hold a cutting edge, so they’re hot-forged from Grade 420 stainless steel and then heat-treated to a hardness of 48 to 52 HRC. Even in the finest cutlery sets, the blade is always 420 while the handle is 304.
Can I put 18/10 stainless steel cutlery in the dishwasher?
Yes. 18/10 is fully dishwasher safe. For the best long-term results, unload the dishwasher fairly soon after the cycle ends, avoid mixing stainless and silver-plated pieces in the same load, and place cutlery handles-down in the basket. Always check if your dishwasher tablet or liquid detergent is an ‘All in One’, if it is then do not use extra salt in the dishwasher as it will already have salt in the formula. Avoid detergents and tablets that use ‘Lemon’, this will corrode even the best quality stainless steel.
How can I tell if my cutlery is 18/10 or 18/0?
Look for a stamp on the back of a fork or spoon. Premium cutlery will be marked “18/10” or “18-10.” You can also try a magnet: 18/0 is attracted to magnets, so the magnet will grip firmly. 18/10 is non-magnetic or only very faintly so. If there’s no stamp and no grade mentioned in the product description, it’s worth asking the retailer which grade the cutlery is made from.
The steel behind your cutlery matters more than most people realise. It’s the foundation that determines whether a fork still gleams after a decade of dinners, or starts to fade within the first year.
