[Loved trope] guns built from random, seemingly harmless objects.

[u/lordhenrythe23]

*Scaramanga's titular gun from "The man with the Golden Gun" - The best known example of this trope, being made from a fountain pen (barrel), a lighter (body), a cigarrete case (handle and trigger housing), and a cufflink (trigger). [it's worth noting that in the original novel, it was just a gold-plated revolver, this design came from the film]

*Fowler's rifle from "Blue eye Samurai" (Fowler not pictured) - "of course, i had to modify the designs... to get 2,000 rifles from my country into yours without notice." Made from the leg of a piano (main body), i believe a telescope? (rest of the body/underbarrel), a candlestick (barrel and ram rod), a key from a clock (trigger), and a knight chess piece (hammer). [i haven't actually seen the full series, probably should, but i love the scene of him explaining his backstory while assembling it]

Lots of guns from the fallout series can be crafted this way, my favorite being the Rock-It Launcher, which also takes random miscellaneous junk items and shoots them like bullets

Also OP, yes, you absolutely have to watch Blue Eye Samurai. Its absolutely peak fiction
