This essay looks at the connection between the design and techniques of longswords. The longsword is perhaps the most iconic weapon of the late medieval and early modern period. However, there are few academic studies on how longswords were used. As well as the use of longswords in general the essay seeks to understand how certain characteristics like blade design or decor can offer clues to how specific swords may have been used. To find out how this kind of weapon was used 10 longswords from northern and central Europe was analysed in terms of design. As well as the longswords four historical fencing manuals from the holy roman empire were studied. The source material was chosen to reflect my own experience whit Germanic medieval/renaissance fencing. Combining study of artifacts and written sources gives this essay the opportunity to explore the several attributes pertaining to the use longswords. As well as examining the books and swords several of the techniques in the manuals have been tested by me and Fencers of Wisby historiska fäktskola.  The study of the source material as well as the tests of the techniques reveal the construction of a sword had an impact on how it can be used. Certain design like the shape of the blade, crossguard and pommel change what techniques are more effective with a particular type of longsword. The early longwords for example seem to have had an emphasis on cutting whilst the later swords became more adapted for thrusting to combat armour. Some of the examined longswords appear to be ornamental and not intended for combat. The more ornamental longswords could however possibly have functioned as a weapon and a symbol at the same time. Sometimes the symbolism is emphasised but even in those cases the swords could often have been used as a weapon if desired or needed.
