1. Prepare Your Blade: If using a lame, ensure a fresh, sharp blade is inserted. If using a razor blade, hold it carefully between your thumb and forefinger. A sharp paring knife should also be ready. You can dip the blade in a little water to help prevent sticking, especially with higher hydration doughs.

2. Position Your Dough: Gently transfer your proofed sourdough loaf onto a piece of parchment paper or directly into your Dutch oven, depending on your baking method. Ensure it’s stable and won’t shift while you score.

3. Hold the Blade Correctly: For most patterns, hold the blade at about a 30-45 degree angle to the surface of the dough. This angle helps create a “ear” – a flap of crust that peels back beautifully during baking. For deeper, more structural cuts, you might hold it closer to a 90-degree angle.

4. Execute a Single, Confident Cut (Basic Ear): For a classic “ear,” make one long, curved cut across the top of the loaf, from one end to the other. Start about 1/2 to 3/4 inch deep. Be confident and swift; hesitation can lead to a jagged cut.

5. Try a Simple Cross Pattern: For a symmetrical look, make two intersecting cuts across the top of the loaf. You can make them straight or slightly curved. Again, aim for about 1/2 inch deep. This allows for even expansion in four directions.

6. Experiment with a Box or Square Pattern: Make four straight cuts to form a square or rectangle on the top surface. You can angle these cuts slightly for a more rustic look, or keep them straight for defined edges.

7. Consider a Wheat Stalk Design: For a more decorative touch, make a long, central cut down the middle of the loaf. Then, make several smaller, diagonal cuts branching off from the central line, alternating sides, to mimic a wheat stalk. These smaller cuts should be shallower.

8. Bake Immediately: Once scored, place your loaf into your preheated oven or Dutch oven without delay. The scoring helps the dough expand as it bakes.
