Weapon Base Data file structure
Like most files in MHXX, weapon base data files have an 8 byte header, the first four bytes of which are 66 66 06 40 and the remaining bytes are an entry count, so adjust the entry count if you add or remove entries (not recommended).
Weapon IDs can be found here
Each weapon type has its own slightly different structure after that, and they are:
GreatSword (00), Sword and Shield (01), Hammer (02), Lance (03), Long Sword (07), Hunting Horn (12) , Bow (10)
The file is weapon??BaseData, and it has 33 bytes per entry after the 8 bytes header
