There's an example for your persona thread inquiry. That sword looks like it was re-hilted and re-ground many times altering it's shape, profile, and performance characteristics over the course of its working life to suit more modern styles as it went on. If it's chain of ownership is true (while carrying the de Bohun arms is interesting, that's quite a tall tale they've spun about its history), it saw battle throughout the age of maille and was retired about the time plate was rapidly advancing. Regardless of who really owned that sword, it's a cool example of the sword as a tool through time. That's one hell of a piece!
Note that the manuscript miniature in the article depicting the Battle of Boroughbridge is actually an early 15th century depiction of an entirely different battle (Battle of Tinchebray 1106). But its time of painting is why it shows everyone in early 15th century armor.
