Swords were also considered expensive and fancy
You got that right, neighbor. How I see it swords, in general, were like a Rolls Royce in modern thinking. Expensive, both in making and in materials, and naturally only those with status had them. Where as in comparison a spear (a simple garden variety, nothing fancy spear) was more a kin to a VW Beetle, just about anyone with a little money could afford one.
And I do agree that Wiki is a good general source of info. But since the content is user created there tends to be a little bias, like the EA games Wikipedia scandal (just type in EA Games on wikipedia and have a good laugh) or it tends to be limited on some subjects. And this comes from a guy who uses Wiki regularly.
And yes, while rapiers and some of their cousins were civilian toys for aristicrats, they were for the most part a bit inaffective in warfare given the fact that they had a frail frame and could break easily, under the right circumstances, and the only form of armor they might be able to penitrait was chain mail (that is if the chain links were big enough and the rapier was narrow enough, mostly likely an epee would work better). To my knowledge the only real fencing sword that saw real warfare was the sabre, likely because its design allowed it to have a good slashing power.
