This is my new favorite rapier.
(I realize I say that for different swords all the time... my love for swords is so fickle!)
The handling on this sword is fantastic! Seeing as the blade was custom, it's the perfect length for me, it is incredibly quick in the hand, and allows for good, quick cuts from the wrist. The flex is excellent: Enough to make a good, safe thrust into my partner, but not whippy at all.
I do have to get used to it not having the fore-quillon, as I attempted to parry with the guard a couple times and got hit because of it! All of my previous rapiers have had this, so I just need to practice more with this one (which won't be a problem! I've hardly put it down since I got it), but that's not really a functional quibble.
