The wrong bread knife crushes a sourdough loaf into a sad squashed brick. The right one slides through the crust and the crumb in three long strokes, leaving a clean cut and the bread’s shape intact. The difference is mostly about the teeth — proper pointed serrations grip and saw rather than scallops which just push. This guide covers the picks worth your money, what to avoid, and why the bread knife is one of the few specialist knives that genuinely earns its space in most UK kitchens.

How we chose these knives
We ruled out scalloped edges in favour of pointed serrations, which cut rather than push, then compared blade length in the 20–25cm range that lets a knife clear a full loaf in one stroke, handle comfort, and value against verified UK buyer reports. These are researched picks, not first-hand reviews, and we don’t accept payment for placement. Read our full methodology →
Why a chef’s knife isn’t enough
A chef’s knife is sharp but smooth-edged, which means it cuts by slicing — and a bread crust isn’t actually that easy to slice. The sharp edge wedges into the crust, then either pushes the loaf down or skids off. By the time you’ve cut through, the crumb structure underneath has been compressed and the slice is misshapen. A bread knife cuts by sawing — the teeth grip the crust and pull it apart, then the pointed tooth tips drop through the soft crumb without compressing it. The result is a clean, square slice with the bread shape intact.
The other case where a bread knife is the right tool: tomatoes (the serrations grip the skin where a chef’s knife slips), cake (the saw action lets you slice without compressing layers), watermelon and pineapple (the length lets you cut all the way through in one stroke), and frozen baguettes or partbake loaves.
What to look for
Pointed serrations, not scalloped. The most important thing. Pointed serrations look like a row of small triangular teeth. Scalloped edges (smooth curves) push more than they cut and are universally worse. If the knife you’re looking at has scallops rather than teeth, skip it regardless of brand.
Blade length: 20–25cm. A bread knife earns its keep partly by being long — long enough to slice all the way through a sandwich loaf in one stroke without re-positioning. 20cm is the minimum; 25cm is genuinely useful if you bake or buy artisan loaves.
Slightly offset blade (optional but useful). Some bread knives (Wüsthof Super Slicer, others) have the handle offset slightly above the blade so your knuckles clear the board when slicing. Worth the small premium if you slice on a board regularly rather than holding the loaf in your hand.
Comfortable for sawing motion. Hold the knife in the shop if you can. The grip you use for bread cutting is different from the chef’s knife grip — more horizontal motion, more wrist involvement.
Avoid “self-sharpening” claims. Marketing nonsense. Serrated knives need professional sharpening every few years; nothing on a knife “self-sharpens”.

Best German
Wüsthof Classic Ikon 23cm Bread Knife
Made in Solingen, weighted handle, slightly more aggressive serrations than the Victorinox. Holds an edge slightly longer and feels more substantial in hand. The right buy if you have other Wüsthof knives or you want something that lasts decades.

Best for Sandwich & Sourdough Bakers
Wüsthof Classic Super Slicer 26cm
The 26cm length plus the offset handle make this the right pick for anyone who slices artisan bread or large loaves regularly. The extra blade length means a full slice in one stroke; the offset handle keeps knuckles clear of the chopping board. More expensive than necessary for occasional bread cutting; genuinely worth the upgrade if you bake or buy a lot of bread.

German Alternative
Zwilling Gourmet 20cm Bread Knife
ZWILLING Gourmet Bread Knife, 20 cm, Special Stainless Steel, Ergonomic Plastic Handle, Black - Made in Germany
Zwilling’s everyday bread knife, made in Germany, with the ice-hardened Friodur blade the brand uses across its ranges. The blade is 20cm rather than the 23cm of the Wüsthof above, so it suits sandwich loaves and tin bread better than a wide sourdough. A good pick if it’s on offer.

What to skip
Anything with scalloped or wave edges. Not serrations, doesn’t grip crust. The cheap supermarket bread knives are universally this style.
Bread knives under £15. Cheap steel, dulls within months, can’t be re-sharpened. The Victorinox is the realistic floor for a knife you’ll keep.
“Reverse-serrated” specialty knives. Marketed at sandwich-shop use; rarely useful in domestic kitchens.
Electric bread knives. Solve a problem nobody has. A good manual bread knife is faster and never needs charging.
Care and sharpening
The good news: a serrated knife stays usefully sharp for years because the teeth do the work even when the cutting edge between the teeth has dulled. The less good news: when it eventually needs sharpening, it has to be done professionally — domestic pull-through sharpeners destroy the teeth, and whetstones aren’t the right tool for serrated edges.
Most knife-sharpening services (£5–£10 per knife) handle serrated knives competently. If you live near a bigger town, Knife Aid (post-it-and-return) and the better farmers’ market sharpeners both do good work. The Victorinox is cheap enough to replace rather than re-sharpen if you can’t find a service.
Hand-wash only, store securely (a knife block or magnetic strip protects the teeth from chipping), and use it on wood or plastic — never glass or ceramic which destroys the teeth.
Bread knife FAQs
What length bread knife do I need?
A 20–23cm blade like the Victorinox Swiss Classic handles most tins and bloomers. If you bake big sourdoughs or slice sandwich loaves, a longer 26cm slicer like the Wüsthof Super Slicer clears the crust in one stroke without sawing.
Serrated or scalloped edge — does it matter?
Yes. Serrations grip the crust and saw through it without crushing the crumb; scalloped edges push more than they cut and don’t grip crust. For a do-everything knife, standard serrations like the Victorinox are the safe choice.
Can you sharpen a serrated bread knife?
Only with care — each scallop has to be honed individually with a tapered rod, and most people don’t bother. The better plan is to buy one good knife that holds its edge for years, like the Victorinox, which is why cheap replaceable ones are a false economy.
Is an offset bread knife worth it?
If you slice a lot, yes — the raised handle keeps your knuckles off the board so you can cut right through in one pass. For occasional loaves a standard straight handle is perfectly comfortable and easier to store.
Which bread knife is best value?
The Victorinox Swiss Classic has a serrated 21cm blade that does the job, for a fraction of the price of the German picks. Start there unless you specifically want a German finish.
