9th Anniversary Maple Katanas have an attack speed of 0.

I still haven't gotten one. I've opened some ~15,000 anniversary boxes and have only gotten 4 or 5 pieces of anniversary gear, only 3 of those being weapons (two one-handed swords and a dagger).

I've only gotten 2 weapons and pretty much have given up trying to get weapons. Event made them too hard to get, I prefer the old Maple weapon events where they just assigned monsters to drop certain items and let people hunt for what they want instead of getting weapons they can't use in random boxes with extremely low rates. I remember spending hours in horny mushroom tree trying to get Maple Llama staff. Felt so rewarding when I finally got it, and I loved its design. Good times.
