[General Sci-fi] Why is it that if someone has a sword it will always be a katana?

If any cyberpunk assassin or future bounty hunter has a sword it is almost always a katana. Why? I mean they're pretty good swords, but there are plenty better ones. Why is the katana always the sword of choice?

Don't swallow this crap about it being more civilized or thinner or lighter or deadlier. There's only one reason.

Katanas are cheap as fuck.

Seriously, look around. Pull open one of those catalog magazines with any kind of blades in it and you'll see someone hocking a katana. Internet store? Katana. Flea market? Katanas. Katanas everywhere.

By the time of the future, everyone will own a katana, even if it's just to act as a backscratcher, letter opener, or to keep doors propped open. The heroes in sci-fi can probably pick one up at the grocery store, in the cutlery aisle. It doesn't matter if the one they're using has shoddy worksmanship, they don't expect it to last longer than a year or so. After that, they'll just turn around and either buy another or borrow it from the nice old lady down the road who only ever uses hers to test whether her cakes are done.
