Not as useful against Replicators as the real thing, but still way better than Asgard weapons.
Although I believe this impressive, apparently working wooden rubber band gun and the page that presents it originate in Japan, I’m not having any luck with machine translation of the accompanying text. So unfortunately I have no other information. If you can identify the maker or other details, and can spare the time, I’d appreciate your comment, below. [Thanks, benj!]
