Blade geometry is a crucial aspect of knife design, influencing both the performance and usability of cutting tools.
The flexibility these blades have illustrates the purpose that they served, as primarily cutting weapons, that could also be used with the thrust.
With the improvement in the defensive capabilities of armor in the High and Late Middle Ages, the cross-section of the sword blade adapted to suit the needs of warriors.
The diamond cross-section could also be hollow ground for greater edge sharpness and thrust efficiency, while retaining strong central ridges.
Distal tapering refers to a blade's cross-section thinning from its base to its tip.
