Cutting with a sword
What exactly means cutting with a sword?
The question may sound funny, but it really depends on arm movement and technique.
We can distinguish between three types of blade movement and the nature of its interaction with the target:
1. sliding motion along the target - this is the move we have when cutting food with a kitchen knife to separate equal pieces evenly and cleanly. we move the edge forward and backward while pressing the knife.
2. spot hit perpendicular to the target - we have such a move when chopping, e.g. with an ax into wood to split it. we hit hard surfaces from top to bottom.
3. circular cutting - it is the movement that lead the long blade in a circle, causing both the impact and the sliding the edge on the target. This is the type of cut that will be most effective and dedicated to bladed weapons.
The effectiveness depends on the type of tool used and our experience with using it. Each of the cutting tools has been designed in such a way that it effectively serves a dedicated purpose.
This is even clearer when we look at how a saber blade works. The curvature of the blade has been used to reduce drag and make a circular motion also result in a sliding motion when cutting the target.
