mostly by warriors. Great blades include:

great blades when used with both hands.
* Katanas serve as single-edged blades when wielded with one hand, as
great blades when used with both hands.
*A character wielding this weapon without also having the 'exotic weapon
proficiency' appropriate to this particular weapon will be considered
