What does bistoury mean?
A bistoury is a long, slender surgical knife designed for making precise incisions, most classically for opening abscesses or draining fluid collections. Its blade may be straight or curved along its edge, and its narrow profile distinguishes it from the broader blades of a standard scalpel. The word belongs chiefly to the vocabulary of surgery, appearing in operative manuals, historical medical texts, and catalogues of antique instruments rather than in everyday speech. Bistouries were staples of the surgeon's case through the eighteenth and nineteenth centuries, and references to them lend writing a distinctly clinical or period flavour. The plural is bistouries. For readers of medical history or fiction set before modern surgical instrumentation, the word is a useful marker of authentic detail, evoking an era when even minor procedures depended on the surgeon's steady hand and a well-honed blade.

Etymology of bistoury
The English word 'bistoury' was borrowed in the late sixteenth or early seventeenth century from French 'bistouri', meaning a small surgical knife. The ultimate origin of the French term is uncertain, though one widely repeated account derives it from 'couteau de Pistoie', a knife associated with the Italian city of Pistoia. It entered English alongside other loanwords describing surgical instruments.
