Establish
If you say a new weapon idea out loud, then it will be established immediately.
Try it out: I want a stabbing weapon with extra weapons that can pop out on the sides. *POOF* You've established a new weapon. And it's been added to the official weapon wiki of the world.

Weapons have to be established in sets (せつ). So you have to make another one that goes with it. Make them cohesive please.
Establish weapons in sets or the people who use them won't be able to match each other.
