The “short katana” would be a wakizashi. It’s a distinct
weapon in its own right and was traditionally part of a samurai’s accoutrements,
though this is probably the least significant issue here.
The combination works in so far as you remember that real
people make really horrible decisions in an attempt to seem cool. The Desert
Eagle is a very flashy, somewhat terrible, gun. You carry one as an aesthetic
choice, not because you want to actually kill someone with it. It’s big, bulky,
unreasonably heavy, and stupidly expensive. The only point to owning one is to
say, “look at what a badass I could be.”
The katana is a very flashy, somewhat terrible, sword. Stop
me if this one sounds familiar; this is a sword you carry as an aesthetic
choice, not because you actually want to kill someone with it, but because you
want to say, “look at what a badass I could be.”
In both cases you’re talking about items that present the
concept of a weapon far more valuable, lethal, and cool, than the real articles
offer. With the katana, there’s also all of the associated cultural baggage. The
katana is, literally, a holy symbol in Shinto. If your character is carrying
one for religious reasons, that’s one thing; but, if they’re looking for “the
best sword,” then, it’s a terrible choice.
It’s also probably worth pointing out that both the Desert
Eagle and the katana require two hands to wield properly. Desert Eagles have a “floating
mag,” meaning the magazine remains somewhat loose in the grip, while locked. If
the operator fails to properly stabilize the pistol, this can result in the
pistol failing to feed, meaning it won’t properly load the next round into the
chamber, and forcing the user to cycle the slide manually. This isn’t an issue
if you’re using the pistol as designed, but if you’re trying to fire it one
handed, because your other hand is occupied with a katana, it could easily
result in a dead man’s click long before the magazine is empty.
There’s a similar issue with the katana, the design works
with the idea that the wielder will be using it with both hands. Specifically
you use your
index and middle ring and pinky finger on your off-hand to control the blade,
while using your main hand for power. The problem with wielding one single
handed should be immediately obvious; you can flail around with it, but you can’t
really get much value from it that way. At that point, you’d almost be better
off with a machete, simply because it would offer a more comfortable grip, and would
be easier to swing.
While wakizashi are frequently matched with a katana and sold
together, they’re not intended for simultaneous
use. The wakizashi had distinct uses, mostly so the samurai would have a blade
they could actually use in doors, but it wasn’t supposed to be dual wielded
with a katana. Think of it like buying a kitchen knife set, sure there’s eight
knives in there, but you’re not going to be using all of them together at once.
I’ll add, I’ve got nothing against a character that has a
reason to use a katana. If it’s a badge of office, a family heirloom, a sign of
their order or training, that’s fine. It’s the idea that “this is the best
possible sword ever,” which I object to. It’s a two-handed sword. It’s not
particularly great. It has a dedicated martial style, predicated on using very
fragile blades, (and historical katanas are exceedingly fragile).
Finally, if you’ve got a setting where firearms are outlawed,
there’s a few problems specific to the Desert Eagle. I mentioned that they were
large and expensive, so let’s break those down a little. First, these are
massive pistols. A Mark XIX Desert Eagle weighs just under four and a half
pounds. For a pistol that is comically heavy. This is also a gun that is over a
foot long. These are large handguns.
They are difficult to conceal. If you’re living in a setting where owning a gun
is illegal, this is the last thing you want to be carrying on the street. (They’re
pretty terrible carry weapons in the real world as well.)
On the current market, with firearms that are legal to buy, a
used Desert Eagle will set you back at least $1,200 ($1,400 to $1,700 is more
likely, for a gun in decent shape). In contrast, if you’re shopping for a solid
conceal carry pistol you can expect to spend somewhere between $400 and $500.
Even high grade “tactical” pistols rarely break $1k, unless they’re collector’s
items (or SIGs). Most “cool” pistols you see on TV probably cost between $600
If you’re wondering why SIGs manage to command higher prices,
it’s because (in most cases) they’re remarkably high quality. I’ve had issues
with the American produced SIG Sauer P226s, but in general SIGs are worth the
The Desert Eagle really isn’t worth the money. As I said
earlier, these are guns you buy to show off, not because you’re looking for a
And, all of this is before you step back and apply the
economics for a setting where getting a handgun is illegal. At that point, you’re
talking about a gun that could easily cost more than an older model car. Those
economics skew against you even harder every time your character pulls the
Desert Eagles come chambered in a couple different rounds.
There’s .357 magnum, .44 magnum, and .50AE. (Technically, there’s also .41
magnum and .440 variants as well.) Gun stores aren’t going to stock a lot, but
you can buy them if you’re using something chambered for it. Also worth noting,
if you’re dropping the hammer on a .50AE Desert Eagle, it will set you back
more than a dollar per bullet. (The current, actual cost in the US is ~$1.35
per round.) But, if you’re in a setting where firearms aren’t easily available,
your black market’s going to need to focus on rounds they can actually sell.
They may keep a little bit around
(and would charge way more than the
price I just quoted), but once it’s gone, getting your hands on more could be
very difficult. In this sense, it would be much safer if your character was
using a firearm that matched to the common calibers in their setting. The
reasoning is, that your black market may not keep much .50AE around (if they
keep any at all), but they probably will stock 9mm, .45, or whatever your
setting’s cops use. It’ll cost substantially more than it would in the real
world, but it will be something your character can buy. It also won’t leave
behind freakishly expensive shell casings every time they open fire. A string
of killings involving a .50AE pistol? That will bring the cops down on their
contacts looking for someone who’s been scavenging around the black market for
those 12.7mm rounds far faster than a few people who got plugged with a black
To a lesser extent, the katana and wakizashi have a similar
issue. Yeah, sure, they’re cool, I guess, but they’re also memorable. If your
character is using a sword (and that’s common in the setting), having the cops
looking for someone using a guy with a katana will result in a much shorter
search ending at their doorstep than someone with a random non-descript sword
or even something like a machete.
If the katana is enchanted, then sure, your character is kind
of stuck with it (up to a point), but it’s still a weapon they’d need to be
somewhat careful about hiding, and more careful about using.
So, yeah, it’s entirely plausible that you’d have a character
who thought all of these were a good idea. If you have a setting where they
could actually get their hands on them is a different question.
If you’re thinking they could use the weapons together, then
no. They could switch between them, but trying to use them all at once would
result in wild flailing, and a malfunctioning pistol.
I can think of, at least, one legitimate reason why your
character might carry around a Desert Eagle (or a katana) in a setting like you’re
describing, and that’s to scare people. If you’re an enforcer for some shadowy
criminal organization, then being able to shove a 14 inch, chrome, monster gun
up someone’s nose is an effective option (and yes, the Desert Eagle is a model of handgun you can press
into someone without disabling it). But, even then, they’d probably carry
something far more practical for times when they were there to kill someone,
and not just put the fear of Elmer Keith into them.
Depending on the setting (or the organization they work for),
then they might carry and use a katana for that kind of intimidation instead.
For instance: If they were Yakuza, it would make some sense. At that point, you
might reasonably get a character who
used that exact set of weapons for intimidation, and would actually use the
katana or wakizashi when provoked.
In general, though, there’s nothing wrong with a character
thinking this is all a good idea. It’s not. But, if they could afford it, they
might go chasing after that concept anyway.
EDIT: As @fox-bright kindly reminded me, it’s the third and fourth fingers on your off hand that you use to control a katana, rather than the first and second. Sorry about that.
