[2025-09-29T13:47:59.165870] [PI reasoning] **Classifying dental instruments**

I need to address a question about instrument classification using GV Black numbers, specifically focusing on whether each instrument has a 3-digit or 4-digit formula. Hand cutting instruments typically fit into these categories. 

For example, the enamel hatchet mostly has a 3-number formula, while the gingival margin trimmer usually has a 4-number formula due to its blade angle. Excavators can have either depending on their design, with some easily fitting into the 3-number category.
