Etymology: Few surgical instruments have a name whose origin is still unsettled. This blade's name came into English from French "bistouri," which was borrowed from Italian "bistori," a word of uncertain origin. Etymologists have proposed several explanations, but none is confirmed, so the trail ends in Italy without a clear source. One suggestion ties it to the Tuscan town of Pistoia, a centre of cutlery making, but this is a guess rather than documented fact. The name has also been spelled "bistoury" and "bistouri" in English, and the blade's form has changed over time. Early versions were used to cut and probe, and the name stayed with a small, pointed knife for precise incisions. The spelling "bistour" given here is a variant of that same word.
