Archaeologist Sue Brunning has a new book on the sword around the North and Baltic Seas. In an interview she brings up a way of thinking about the parts of a sword which is worth pondering:
There are common features that all swords had to have in order to be swords.
First, a blade – which I describe in the book as the “body” of the sword because it is the part that “does the work”, from a physical point of view; it is usually concealed beneath “clothing” (the scabbard) and only those most intimately acquainted with the sword would see and come to know its finer details. The blade also, like a body, became the repository for history, reputation, character…
Second, a hilt (or handle), which I describe as the “face” because this was the focus of a sword’s visual identity – it was the part that most people could see and come to recognise, as it was not concealed by “clothing” like the blade was. Hilts, like faces, had unique features manipulated by their owners; they could be altered to shape their identities in a desired way; and eventually, as we all know, they would show signs of ageing – wear patches, like wrinkles.
Next, the scabbard – the early medieval sources disagree to some extent over how essential this component was, but in reality it was quite important. It enabled you to carry the sword on your body, as well as keeping it bright and sharp thanks to the fur lining.
Within these three basic components, there was huge scope for customising your weapon in how it was decorated, the materials that were used and so on. This was a way to make your sword your own, or – I would argue – its own!

I think that thinking about all three parts lets you understand swords much better than focusing on just one. If you aren’t a sword person, you might be surprised to learn that the standard typologies of Viking swords and rapiers just consider the hilts- which is like assigning cars a typology based on the bumper and paint, but the hilt is the easiest part to divide into groups and the people writing the typologies had never used a sword.
