Doctor's Concealed Knife

A small, utilitarian blade with a dark, worn handle designed to be hidden from casual view. The Doctor carries it as a personal tool for cutting and probing, its edge honed and thin enough to slip into evidence bags or slice river fruit without revealing his intentions. Romana and Biroc first notice its absence when an amphibian covertly relieves him of the knife during a tense negotiation in the Great Hall, marking the first visible act of the planet's undercurrent aggression.
