Let's recap the weapons (can be murder weapon or other weapon) of 2005 I know it's crazy, but it's a good way to promote world peace, haha.. maybe not.
Try to collect the characters, and the series name. Group them in the following categories:
(1) Guns (there are a LOT, let's not count The Academy, because that series has guns everywhere) -list at least 10
(2) Knife
(3) Swords - list at least 10
(4) bombs
(5) other (describe the weapon) - list at least 10
