Bread Lame vs Razor Blade: Which Scoring Tool Do You Need?

When I wrote my scoring guide, several readers asked: do I really need a bread lame, or can I just use a razor blade from the hardware store? The short answer is that both work, but they serve slightly different purposes. Here is the breakdown.

The Bread Lame

A bread lame (pronounced "lahm") is a handle that holds a razor blade, usually at a slight curve. The curve is the key feature. When the blade is flexed, it creates a cut that goes under the surface of the dough at an angle rather than straight down. This angled cut is what produces an "ear" on your bread, that raised flap of crust that opens dramatically during baking.

Lames are comfortable to hold, consistent in their angle, and make the primary score on a boule or batard very easy. If you bake one or two loaves a week and mainly do simple scoring patterns, a lame is probably all you need.

The Straight Razor Blade

A bare razor blade (or one held in a straight handle without flex) cuts vertically into the dough. This produces clean, precise lines that are ideal for decorative scoring patterns like wheat stalks, leaves, or geometric designs. Straight cuts do not produce the same dramatic ear that a curved lame does, but they give you much more control for intricate work.

Which Should You Buy First?

Start with a curved lame. The primary score is more important than decorative patterns, and a good ear is one of the most satisfying things in bread baking. Lames cost between five and fifteen dollars and come with replaceable blades. Replace the blade every four to five bakes, or whenever it starts dragging instead of gliding through the dough.

If you eventually want to try decorative scoring, add a straight holder or just grip a fresh razor blade carefully with a folded piece of tape on the back edge. There is no need to spend money on specialty tools until you know you enjoy the artistic side of bread baking. But you should absolutely invest in a basic lame from day one. It makes a real difference in your results.

Bread Lame vs Razor Blade

The real difference shows up in technique. A bread lame holds the blade on a handle so you can flex it into a slight curve, and that curved blade is what produces the dramatic raised "ear" on a well-scored sourdough. A bare razor blade is flat and rigid, so it tends to cut straight down rather than under the surface — fine for a single decisive slash, but limiting if you want patterns or a lifted ear.

Angle and depth matter more than the tool itself. For an ear, hold the blade at roughly a 30-45 degree angle to the surface, almost parallel, and cut about 6-12 mm (a quarter to half inch) deep in one confident motion. A shallow, low-angle cut creates a flap of dough that peels back and bursts upward in the oven; a vertical, straight-down cut opens evenly and is better for decorative scoring. Score cold dough straight from the fridge — it's firmer and the blade drags less.

Use a curved blade (lame) when you want a single bold ear or sausage-style expansion cut down the length of a batard. Switch to a straight blade or hold the lame flat when scoring decorative leaf and wheat-sheaf patterns, where you want clean shallow lines that stay defined rather than blowing open.

Frequently Asked Questions

What is a bread lame?

A bread lame (pronounced "lahm") is a handle that holds a razor blade, used to score the surface of bread dough before baking. The handle lets you flex the blade into a curve and control the angle precisely, which is how bakers create the raised "ear" on artisan loaves. Most lames take standard double-edge razor blades.

Can I use a razor blade instead of a lame?

Yes — a bare double-edge or utility razor blade scores dough perfectly well, and many bakers start with one. The trade-offs are safety (your fingers are near a bare edge) and that a flat blade can't flex into the curve needed for a pronounced ear. For straight slashes it works fine; for curved decorative scoring a lame is easier.

What angle should I score sourdough at?

For a raised ear, hold the blade at a low angle of about 30-45 degrees to the dough surface, nearly parallel, so you cut a flap rather than straight down. For decorative patterns, hold the blade more vertical (closer to 90 degrees) for clean, defined lines. The shallow angle is the key to dramatic oven spring on the cut.

Why do you score sourdough?

Scoring gives the loaf a controlled place to expand as gas rapidly releases in the oven (oven spring). Without a score, the bread bursts unpredictably along its weakest seam, often on the side or bottom. A deliberate score directs that expansion, controls the final shape, and creates the decorative crust pattern.

What is the best bread lame for beginners?

A simple straight-handle lame that takes standard double-edge blades is the best starting point — inexpensive, easy to load, and easy to control. Look for a comfortable grip and a design that lets the blade curve slightly. Avoid overly fancy multi-blade gadgets at first; consistent technique matters far more than the tool.

How deep should I score bread dough?

For a single ear cut, score about 6-12 mm (roughly a quarter to half inch) deep in one smooth motion. Decorative surface patterns are shallower, around 3-5 mm, just breaking the skin. Too shallow and the cut seals over; too deep and the loaf can deflate.
