I'm surprised at how quickly I was able to find these:
A pirate's cutlass.
The high priest of Odin's spear.
Haley's bow.
Durkon's hammer.
A coliseum greatsword.
Roy's old club.
Some fun honorable mentions:
Shadow Roy has a gun (but it's not used in combat, and I'm not sure if imaginary Roy would count anyway)
Roy breaks Malack's staff and throws it a vampire's face (but this is definitely stretching what would be considered "combat")
Roy is "wielding" a shuriken here (he doesn't actually throw or use it, but he is technically holding it in a real combat where the object was used )
Roy flattens Belkar with a wooden sword (I think this one should probably count, but it is stretching the definitions of both "weapon" and "real combat")
