If it's "assumed", you can't claim they're not considered Wonder Weapons. And just because it's buildable and an improvised weapon made by scrap doesn't mean it's not a Wonder Weapon. They are all powerful and unusual weapons. And it's not necessary that a Wonder Weapon must shoot odd projectiles as well. The Spork is much more powerful than the three, and a frigging golden spork that deals more damage than a full magazine of a submachine gun is quite unusual, wheres Bowie Knife, Sickle and Galvaknuckles are as powerful as you realistically would expect. Blundergat is a bit debatable, but it is really powerful and is quite unusual. Acid Gat is just the upgraded version.

Regardless, it's this wiki's definition of a Wonder Weapon as I said, not necessarily every single other places'.
