The grade swords

there was some complaints that some people were hoarding some rare cannon swords.However it was quite clear that no one had claimed them and it was open for anyone. but it seems to some people these swords are quite important,so i would like to volunteer myself to make a list of all the canon weapons in the one piece universe and whoever wants to use them or claim them, we would see and according to the circumstances allow the person to claim the canon weapons
