[2025-10-02T03:47:54.845458] [PI reasoning] **Considering harvesting instruments**

I think the Humby knife is a likely candidate here because it has an adjustable roller for thickness, which could make it suitable for manual harvesting. However, if the user is asking for a general term, it would be a dermatome, since it’s specifically used for harvesting grafts from healthy areas. Since the question is about split-thickness skin grafts, I would lean towards dermatome being the best option. I'll verify this quickly!
