Scoring is the quick cut you make on the top of a loaf just before it goes in the oven. It isn't just decoration. As the dough expands in the oven, it needs somewhere to open. A good score controls where the loaf bursts, helps it rise evenly and creates the raised "ear" that many sourdough bakers chase.
The tool for the job is a bread lame (pronounced "lahm"): essentially a razor blade on a handle. This guide covers the main types, what to look for, how to score well, and how to handle blades safely.
A note on how we recommend: we haven't lab-tested lames. Recommendations are based on design, manufacturer information and widely shared experience from home bakers. Check the current listing for blade compatibility and what's included.
Why scoring matters
When a loaf hits a hot oven, gas and steam expand quickly. The crust sets fairly soon after. Without a weak point, the loaf tears wherever the surface is thinnest, often at the side or base, giving a lopsided loaf.
A deliberate score:
- Directs expansion to where you want it
- Helps oven spring by letting the loaf open freely
- Creates an ear when cut at a shallow angle
- Adds a signature look
A dull knife drags and tears the dough. A very sharp, thin blade glides through, which is why lames use razor blades.
Types of bread lame
| Type | How it works | Best for | Watch out for |
|---|---|---|---|
| Straight lame on a stick | Blade mounted flat on a thin handle | Straight cuts, patterns, beginners | Less suited to dramatic ears |
| Curved lame | Blade bent into an arc on a handle | Ears on batards, angled cuts | Takes a little practice |
| Handle with interchangeable blade holder | Blade clamps into a holder; often switchable straight/curved | Flexibility, easy blade changes | Check blade compatibility |
| Disposable lame | Plastic handle with fixed blade | Trying scoring cheaply | Can't change blade; more waste |
| Razor or sharp knife | No handle or regular knife | In a pinch | Less control, safety risk |
Straight vs curved
A straight blade cuts vertically into the dough. It's ideal for decorative patterns, crosses and simple slashes. A curved blade lets you cut at a shallow angle more easily, lifting a flap of dough that opens into an ear. Many lames let you mount the blade either way.
What to look for
1. Comfortable, secure grip
You need control over angle and depth, so a handle that feels secure matters. Wooden, metal and plastic handles all work. Some bakers prefer a longer handle; others prefer a short, compact tool for precision.
2. Easy, safe blade changes
Blades dull quickly. You want a design where swapping blades is simple and doesn't require you to handle the sharp edge much. Look for designs that clamp or screw the blade in securely.
3. Standard blades
Many lames take standard double-edged razor blades, which are widely available and inexpensive. Proprietary blades can be harder to find. Check the listing to confirm.

4. A protective cover
A cover or sheath protects your fingers when you reach into a drawer, and protects the blade edge. Some lames come with a leather or plastic cover, and some magnetic designs store the blade safely.
5. Straight and curved option
If you're not sure which you prefer, a lame that lets you use both is a good first buy.
Our picks by type
Best for beginners: a classic wooden-handle lame
Who it suits: new bakers who want a simple, inexpensive tool that takes standard blades.
A thin wooden stick with a slot for a double-edged blade is the traditional design. Bend the blade over the stick for a curved cut, or mount it straight.
- Pros: inexpensive, simple, standard blades.
- Cons: blade changes are a bit fiddly; often no cover.

Best all-rounder: a lame with a blade holder and cover
Who it suits: bakers who score every loaf and want easy blade swaps and safe storage.
Designs with a dedicated holder clamp the blade securely and let you swap quickly. Many include a cover, and some can switch between straight and curved. Wire Monkey is one well-known maker of this style.
- Pros: easy blade changes, secure blade, often includes cover.
- Cons: costs more than a basic stick.
Best for ears: a curved lame
Who it suits: bakers chasing a pronounced ear on batards.
- Pros: makes angled cuts easier.
- Cons: less suited to detailed decorative work.
Best for decoration: a straight, fine-point tool
Who it suits: bakers who like wheat patterns, leaves and decorative scoring.
A straight blade on a narrow handle gives fine control for shallow decorative cuts alongside a main expansion score.
How to score sourdough
- Chill the dough. Dough straight from an overnight cold proof is firmer and much easier to score cleanly.
- Dust the surface lightly with flour if you want contrast between the score and the crust.
- Hold the blade at the right angle.
- For an ear: hold the blade at a shallow angle (roughly 30 to 45 degrees to the surface) and cut along the length of a batard, slightly off center.
- For decorative cuts: hold the blade more upright and cut shallowly.
- Cut with confidence. Use one smooth, quick motion. Hesitation drags the dough.
- Go deep enough for the main expansion cut, typically around a quarter to half an inch. Decorative cuts are much shallower.
- Load straight away into a preheated Dutch oven or bread pan.
Common scoring patterns
- Single slash along a batard for a classic ear
- Cross on a boule for even expansion
- Square or hash for a boule that opens like a flower
- Wheat stalk or leaves shallow decorative cuts, paired with one deeper expansion cut
Troubleshooting
The blade drags and tears. The blade may be dull; change it. Chill the dough before scoring, and cut in one quick motion.
No ear forms. Use a shallower angle, cut more decisively, and make sure the dough isn't over-proofed. Over-proofed dough lacks the strength to spring open. Good fermentation matters as much as technique: see why is my sourdough dense.
The score seals up. Cut a little deeper and make sure there's plenty of steam early in the bake, such as baking covered in a pot.
The loaf bursts at the side. The score may be too shallow or the dough under-proofed.
The dough sticks to the blade. Wet the blade slightly, or dust the surface with flour before scoring.
Blade safety and care
- Change blades often. A fresh blade is safer, because you don't need to press as hard.
- Handle blades by the blunt edges.
- Use the cover every time you put the lame away.
- Dispose of old blades safely in a sealed container such as a blade bank or a labeled jar.
- Keep lames away from children.
- Dry the blade after use to prevent rust.
Building a scoring routine
Good scoring is mostly about preparation and repetition. A simple routine helps:
- Set up before you turn the dough out. Have the lame uncovered, a fresh blade fitted and your parchment ready, so the dough isn't left sitting while you search for tools.
- Plan the cut. Decide where the main score will go before you touch the dough. On a batard, a single long cut slightly off center is the easiest place to start.
- Practice on every loaf. Take a photo of each score before baking and of the finished loaf afterward. Comparing the two quickly shows how angle and depth change the result.
- Keep decorative cuts shallow. They're for looks; the deeper expansion cut does the real work.
Frequently asked questions
What is a bread lame?
A bread lame is a scoring tool: a thin, very sharp blade, usually a razor, mounted on a handle. It's used to cut the top of a loaf before baking so the loaf expands in a controlled way.
Can I score bread with a knife?
You can use a very sharp, thin knife, but most kitchen knives drag through soft dough. A razor blade cuts more cleanly with less pressure.
Is a curved or straight lame better?
Curved blades make it easier to cut at a shallow angle for an ear. Straight blades are better for decorative patterns. A lame that switches between both is a good first choice.
How often should I change my lame blade?
When it starts to drag. Many bakers change blades every few bakes. Because double-edged razor blades are inexpensive, swapping often is easy.
How deep should I score sourdough?
For the main expansion cut, around a quarter to half an inch is common. Decorative cuts are shallower.
The bottom line
A simple lame that takes standard double-edged blades is all a beginner needs. If you score every loaf, upgrade to one with a secure blade holder and a cover. Chill your dough, cut at a shallow angle with one confident motion, change blades often, and your loaves will open beautifully.
