My name is Anon e Mouse Jr., and I'm a Kingdom Hearts fan.
And I've contributed to this wiki before, back when it was part of the Final Fantasy wiki. Mostly on the "How to beat various bosses from the first game" page.
What follows is my list of Keyblades from Kingdom Hearts Birth by Sleep. It was in compiling this list that I was able to fill in two of the nearly-blank pages on this wiki.
Keyblades unique to specific characters:
Earth Shaker - Terra's default Keyblade. Later turns into Gaia Bane after the Destiny Islands event.
Gaia Bane - Terra's later Keyblade. Currently in the hands of the Lingering Sentiment (Terra's armor), in the Keyblade Graveyard.
Chaos Reaper - a Keyblade wielded by Terra. He obtains it after the destruction of Land of Departure.
Dark Biter - a Keyblade wielded by Terra. He obtains it after clearing a mission in the Mirage Arena.
Rain Fall - Aqua's default Keyblade. Later turns into Rain Storm after the Destiny Islands event.
Rain Storm - Aqua's later Keyblade. Currently with Aqua's armor in the Chamber of Repose, in The Castle That Never Was.
Destiny Place - a Keyblade wielded by Aqua. She obtains it when Kairi gives flowers to Aqua during their encounter. Riku somehow gained access to this form as well at a later time, turning his Keyblade into the Destiny Place, and gave it to Kairi to use during Kingdom Hearts II.
Bright Crest - a Keyblade wielded by Aqua. She obtains it after creating Castle Oblivion from the ruins of the Land of Departure with Master Eraqus's Keyblade.
Fresh Breeze - Ven's default Keyblade.
Rascal Flame - a Keyblade wielded by Ven. He obtains it after speaking with Isa and Lea.
Lost Memory - a Keyblade wielded by Ven. He obtains it during a visit to the Destiny Islands, after he remembers his past as Master Xehanort's apprentice and realizes Vanitas's origin.
Eraqus's Keyblade - Master Eraqus's Keyblade. Currently in the hands of Aqua, in the Realm of Darkness. Eraqus's heart is inside Terra's heart.
Master Xehanort's Keyblade - just what it sounds like. Was still accessible by Xehanort after his heart was transferred into Terra's body, but after losing his memories of his true identity (following his battle with Aqua in Radiant Garden, he apparently lost the ability to access it.
Note: It is still unknown what has become of Terra now that Xehanort, his Heartless ("Ansem"), and his Nobody (Xemnas), were destroyed. Terra is seen with Ven in what appears to be the Land of Departure after the events of Kingdom Hearts II, and he utters Sora's name with a hopeful smile (as does Ven). The same applies for both Master Xehanort and Master Eraqus, the latter's heart now residing within Terra's. This will likely be explained in a future installment.
Star Seeker - King Mickey's original Keyblade. Later passed to Sora by way of Yen Sid; Mickey apparently got it back later on.
Vanitas's Keyblade - just what it sounds like. Presumed lost with the destruction of Vanitas.
Vanitas's X-blade - this version of the X-Blade was intended to be used to unlock Kingdom Hearts and flood the worlds with darkness. Fortunately, it was destroyed by Aqua.
