Best Bread Lame for Scoring Sourdough
How to choose a bread lame for scoring sourdough: fixed vs interchangeable blades, angle, safety and spares — plus the scoring tool we actually use.

Quick answer
A bread lame for scoring sourdough is the small tool with the biggest visual payoff. The score you cut into a proofed loaf is a controlled weak point: as the oven heat hits, gas pushes through that cut and the flap lifts into an "ear" while the rest of the crust sets. A confident score needs a sharp, shallow-held blade — and that's exactly what a lame is built to give you. A knife can sort of do it, but it's thick, drags, and tears the skin.
Why a lame matters
Scoring isn't decoration — it's pressure relief. An unscored loaf bursts wherever the weakest spot happens to be, usually mid-side, with no ear and an uneven shape. A lame lays down a clean, deliberate cut so the loaf opens where you want, keeps its height, and bakes into the round or batard you shaped. A sharp razor held at a shallow angle is the whole trick; the handle just lets you hold it steady and safe.
What to look for in a bread lame
- Sharp, fresh razor blade. The single most important factor; dull blades drag and tear.
- Interchangeable blades. Swap a fresh razor in seconds instead of retiring the whole tool.
- Shallow, controlled angle. A good lame lets you hold the blade near-parallel to the dough for that ear.
- Comfortable, light handle. You want control, not a heavy grip that fights the cut.
- Safe storage. A cover, sheath, or retractable holder so the bare blade isn't loose in a drawer.
- Standard blade size. Uses common double-edge razors you can buy anywhere.
Types of lame compared
| Type | Good for | Blade | Pros | Cons |
|---|---|---|---|---|
| Interchangeable-blade lame | Everyday home baking | Standard razor | Fresh blade anytime, cheap to run | Blade can loosen if poorly made |
| Fixed-blade lame | Minimalist setups | Permanently set | Never loosens, tidy | Replace whole tool when dull |
| Curved-blade lame | Decorative curved scores | Razor, curved | Pretty arcs | Niche; less versatile |
| Pivot/rolling lame | Consistent angle repeats | Razor on arm | Repeatable angle | Bulkier, more to clean |
Interchangeable-blade lame
Pros: pop in a fresh razor when the edge dulls; uses cheap, common blades; light and easy to control. Cons: a cheaply made one may let the blade shift — buy one with a secure holder.
Fixed-blade lame
Pros: the blade never wobbles and the tool looks clean on the bench. Cons: once the edge goes you replace the entire lame, which costs more over time than spare razors.
Curved and pivot lames
Pros: curved blades make decorative arcs; pivot arms repeat a consistent angle across loaves. Cons: more specialized and bulkier than the simple handle-and-razor that most bakers need.
Our recommendation
Score just before the loaf goes into the preheated Dutch oven, hold the blade at a shallow angle, and don't second-guess the cut.

Frequently asked questions
Fixed blade or interchangeable blades — which is better?
Interchangeable is more practical. A razor dulls after a few loaves and a dull blade drags and tears the skin; being able to pop in a fresh blade mid-session keeps scores clean. Fixed-blade lames look tidy and never loosen, but you replace the whole tool when the edge goes. For home use, interchangeable wins on cost and convenience.
What angle should I hold the lame at?
A shallow angle — roughly 30 degrees to the dough — gives the classic 'ear' where the flap lifts as the loaf bakes. Steeper, near-vertical cuts score deeper but open less dramatically. Practice the shallow drag; it's the move that makes a loaf look bakery-made.
Are bread lame blades just standard razor blades?
Most lames take a standard double-edge razor, the kind sold in any pharmacy. That's a feature: blades are cheap and everywhere, so you can keep a stack of fresh ones. Confirm the lame you buy uses a common blade size so you're never stuck waiting on a special order.
How do I store a lame safely?
A lame is a bare razor, so treat it like one. Many come with a blade cover or sheath; if not, cap the blade or retract it, and keep it away from dish towels and hands. Replace the blade the moment it starts to drag rather than pressing harder.
