Hi, I'm sorry to sound preachy, but you guys should really know this. The various sport fencing swords (epee, foil, and saber) are all essentially developments of the 18th century smallsword, which is very much a lethal weapon.
No. The foil and epee are developments from the 19th-century French
epee du combat (dueling sword), which was significantly longer (4-6 inches) than a typical smallsword.
The foil was specifically and exclusively for teaching. Epees began as fully functional dueling swords, except that a button was run through to stop penetration beyond a half inch. Once in a while, this button could come off during friendly bouts, with tragic results. To prevent this, swords were made with blades that had a
point d'arret--the button was integral with the blade. This "thumbtack point" was then replaced by a three-prong
point d'arret then replaced with a blunt point covered by rubber or a similar substance. From that point, onwards, epees became successively, thinner, lighter, and more flexible.
The sabre had nothing at all to do with the smallsword. In Italy and Hungary (the Austro-Hungarian Empire and its dependents, essentially), it became popular to duel with cutting swords. Since duels were not a matter of charge hard, hack hard, wheel about and do again, dueling sabres became significantly lighter than military sabres. The fencing sabre is an even lighter descendent of the practice versions of this weapon.
Smallswords look nearly identical to an epee or a foil, and are the same size (around 34-36" in total length) except that the blades are stiffer, and of course, pointed.
Smallswords were a few inches shorter--the style of combat was different, too. It's almost nose-to-nose when compared to the later French and Italian schools.
The rapier, by contrast, is a very large weapon, usualy close to four feet long, and fairly heavy. Early transitional rapiers, weapons like sideswords, did have blade presense and could cut effectively.
That depends upon the specific era. Early on, they tended to be shorter, and at the end of the era, they were also shorter. You err in grouping transitional rapiers with the so-called "sidesword" (a horrid neologism that was invented in the past three to five years and never used historically). Transitional rapiers were at the end of the rapier era--they were transiting into smallswords.
