To unlock the Handcannon, you need to finish a new game on Professional Difficulty without using any bonus weapons including the Infinite Rocket Launcher. Take note that this does not work with New Game Plus, so it will have to be a new save file.

Alternatively, you could also unlock the Handcannon by getting an S rank or higher in all 3 stages in Mercenaries Mode.

Primal Knife

Weapon	Unlockable Perk	How to Unlock Perk
Primal Knife 1000 CP	Indestructible	Purchase all upgrades or use Exclusive Upgrade Ticket from Merchant

To unlock the Primal Knife, you need to destroy all 16 Clockwork Castellans found in each chapter of the game. This can be done from different save files and don't need to be from one playthrough.

Cat Ears (Infinite Ammo Accessory)

Although not technically a Weapon, the Cat Ears Accessory grants Infinite Ammo to all weapons making it the most powerful upgrade in the game.

However, it doesn't come easy, requiring an S+ Rank on Professional Mode to unlock. Since New Game Plus is not allowed for S+ Rank, you'll need to give it everything you've got with the other Bonus Weapons to try to win this one.
