									<p><em>Supervisor: Søren Ulstrup</em></p>
<p>In medieval action films, there are often long and drawn-out sword fights, where the combatants' swords clash edges again and again. Is this realistic, or would the swords quickly become unusable?</p>
<p>In this colloquium, I will combine simple mechanics and steel metallurgy to analyse sword strikes. I will propose a simple mechanical model in order to determine the speed of a blade as it strikes and derive an expression for the upper limit of the torque a wielder can apply without damaging the sword. I will discuss the limitations of the simple mechanical model based on the microscopic properties of steel. Finally, I will analyse scanning electron micrographs and images of damaged blades in order to estimate realistic damage.</p>
<p>My simple model indicates that the weight of the blade itself is sufficient to cause permanent edge damage during edge-on-edge collisions. Finally, I conclude that historical swords would be damaged by regular strikes, rendering most fictional sword battles inaccurate.</p>
