I really like Bloodborne's transforming weapons.  From the instant I first saw them, I thought 'this RWBY in a super-gritty Victorian time'.

For those uninitiated, Bloodborne has low-tech examples of:
A saw that is also a cleaver
A saw that is also a spear
A hatchet that is also a waraxe
A cane that is also a bladed whip - Threaded Cane
A pile bunker that is also a hidden blade - Stake Driver
A rapier that is also a gun (hmm) - Reichterpalasch
A sword that is also a bigger sword - Ludwig's Holy Blade
A sword that is also a giant mallet - Kirkhammer
A sword that is also two knives - Blades of Mercy
A scimitar that is also a scythe - Burial Blade
A katana that is also a katana that also kills you - Chikage
A spear that is also a gun - Rifle Spear
A mace that is also a Van der Graaf generator - Tonitrus

You're forgetting a few.
A Katar that transmogrifies your other arm into a beastly one - Beast Claw
A giant wooden wheel that opens up into a blood skull wooden wheel - Logarius' Wheel
A spear that is also a shotgun - Rifle spear

And if you want to consider the upcoming Old Hunter's Expansion...Which was confirmed to have about 10-15 new weapons...
