All armor and weapons, except enchanted, can break in BG1. Katanas were added in BG2, where this wasn't the case anymore. They were then re-imported into BG1 by the EE – without extra adding the "breakable" feature (it's an item ability and has to be part of the item file, no general game mechanism, technically spoken).
