Best bread lame for sourdough

One clean, confident slash decides where the loaf opens. Score with a real lame and you get an ear; score with a butter knife and you get a crater. The choice comes down to the curve, the blade, and a grip you can control.

The short answer: For most bakers the best bread lame is a classic wooden handle that holds a standard double-edge razor on a bow — the curve is what lets you cut shallow and lift an ear. Want comfort? An ergonomic grip. Either way, the real secret is a fresh blade — keep a cheap bulk pack on hand.

What actually matters

  1. 1. The curve (bow)

    A bowed blade cuts at a shallow angle and undercuts a flap that lifts into an ear. A straight blade is for clean decorative cuts. Most lames do both — bow it for ears, run it straight for patterns.

  2. 2. The blade

    Standard double-edge razor blades — cheap, universal, replaceable. A sharp blade slices clean; a dull one drags and deflates. This, not the handle, is what makes the cut.

  3. 3. The grip

    You're controlling depth and angle by feel. A handle you hold comfortably gives a more repeatable score. Ergonomic grips help if the thin classic stick feels fiddly.

  4. 4. Storage / safety

    These blades are wickedly sharp on both edges. A cover or case isn't a luxury — it's how you keep a drawer safe and the blade undamaged.

What to skip: expensive “designer” lames before you can score consistently, and gimmick multi-blade tools. A simple handle and a fresh blade out-score almost anything — the skill is in the hand, not the price tag.

Common questions

Do you need a lame, or will a knife work?

A very sharp knife or a bare razor blade can score a loaf, and plenty of bakers start that way. But a lame holds the blade on a slight curve and lets you cut at a shallow angle, which is what creates a raised 'ear' rather than a flat split. It's an inexpensive tool that visibly improves how a loaf opens, so most bakers pick one up early.

Curved (bowed) or straight blade for scoring?

A curved/bowed blade is the classic choice for an ear: held at a shallow angle, it undercuts a flap of dough that lifts as the loaf springs. A straight blade is better for simple, decorative straight cuts and very wet doughs where you want a clean vertical score. Many lames let you bow the blade or run it straight, so you can do both.

What blades does a bread lame use?

Almost all lames take a standard double-edge safety razor blade — the same kind used for shaving — which is why they're cheap and universally available. Buy a bulk pack and swap to a fresh blade when the cut starts to drag; a sharp blade is the single biggest factor in a clean score.

How do I score sourdough so it gets an ear?

Use a fresh blade, hold the lame at roughly a 30° angle to the surface (not straight down), and make one confident, continuous cut about 1 cm deep just off-center. The shallow angle undercuts a flap that lifts during oven spring — that's the ear. Score a cold, well-proofed dough; warm or over-proofed dough drags and won't hold the cut.

How sharp does the blade need to be — and how do I store it?

Very. A clean score needs a blade that slices without pressure; a dull one drags and deflates the surface. Replace blades regularly — they're cheap. Store the lame with its cover on or the blade removed; double-edge blades are sharp on both sides and a drawer is the wrong place for an exposed one.
