2Hand weapon conversions to 1Hand Weapons

[ChaosSlayerZ]

I am not really following what is that you wanting to do.
Do you want weapons with 2handers models to be used in 1hand ? - this can be achieved by running SQL query that tracks down weapon skill type assigned and changes it.
Do you want a COPY of weapons with 2handers models to be used in 1hand ?
This would require a more comprehensive query to make copies of weapons with 2h skill type.

At the same time - you can assign ANY weapon model to any weapon and any skill or class. You can have a Wizard shooting arrows from Paladin's Epic Sword as if from a Bow. And arrows can look like Centy Long Swords...
