Visual representation of mass distribution

The mass distribution of swords is a well-known component of their performance and handling feel. Although sword makers have to control it through a variety of means, from a user perspective, only three parameters are needed to completely describe it: total mass, centre of gravity, and radius of gyration. They are well known of physicists. However, their values are not in direct relation with what we perceive when using a sword. Because of this, their usefulness has been questioned and their measurement in the sword community is still scarce. In this article, I will demonstrate how to build a more visual representation of the mass distribution of swords, with an application on five swords of my collection.

Cutting mechanics – hints from sources

How to move when cutting with a sword? While the question may seem simple, the answers are actually quite complex and diverse. In this post, I want to expose some things that can be found in sources to inform our cutting mechanics. This provides a starting point for experimentation, interpretation and training that is firmly grounded in history.
