The Elmslie typology is a system for classification and description of the single edged European bladed weapons of the late medieval and early baroque period, from around 1100 to 1550. It is designed to provide classification terminology for archaeological finds of single-edged arms, as well as visual depictions in art. It includes swords which are from the Europeans Middle Ages (approximately 11th through 16th centuries) and currently breaks them down into five main types, which each have several subtypes. Historian and bladesmith James Elmslie introduced the typology 2015,[1][2] as a complement to the Oakeshott typology which covers double edged swords of the same periods.
