This one can really go either way, depending on injuries
sustained. So, let’s parse this out a bit, because I might not have been really
clear about this in the past.
Shallow nicks won’t do much. You’ll lose blood, but not at an
appreciable rate. You’ve almost certainly sustained a few of these in your
life. From a writing perspective these are basically cosmetic. From a medical
perspective they’re not much more. A sword or knife can absolutely inflict
There are rare circumstances where these immediately
relevant. Cuts to the forehead can cause blood to get in the victim’s eyes. In
combat, this is a debilitating situation. Blood that gets onto the palm can
make it more difficult to grasp objects or weapons. (Fresh blood is quite
slick. As it dries it will become sticky, so the effect is reversed at that
When you’re talking about lots of cuts, then you’re probably
talking about this kind of injury. Individually these aren’t dangerous, but if
they start stacking up, blood loss is cumulative, so they can potentially
become life threatening, but that’s not a likely outcome for a duel.
Incidentally, if you’re writing a scene where characters are
dueling to first blood, then these cuts qualify. In fact, that’s what the
duelists will aim for. It’s the easiest kind of injury to sustain, and if the
participants don’t want to kill one
another, this is the safest route to victory.
When I’ve been talking about injuries that create a decisive
advantage, I’m talking about deeper cuts; ones that open up veins or debilitate
limbs. Injuries where bloodloss will lead to impairment and death.
In a duel, these will kill you. When I say things like, “with
first blood, the clock is ticking, and your character will die if they don’t
find a way to turn the fight around,” I’m talking about these deeper injuries.
A person can survive a few shallow cuts without much ill effect, and in most
cases can survive quite a few without aid. Deep cuts are immediately dangerous.
Here’s the problem with this: I’m talking about these like
they’re two separate kinds of wounds; they’re really not. They’re both cuts. If
we’re being technical, the deeper variety are “lacerations.” But, that makes it
sound like there’s a clean delineation between these injuries which simply
So, I’m going to step back and put this in abstract terms, as
they apply to characters for a moment.
Characters can suffer “cosmetic injuries.” These will result
in bleeding. As I mentioned earlier, blood After the fight is over, they’ll
hurt. Unless your character is getting covered in these things, they’ll never
kill them. These can be sustained anywhere, but when you’re talking about
strikes to the forearm (except along the inner arm) or to the face, bone will
usually stop the strike before it gets to deep.
Characters can suffer “wounds.” These will result in a lot of
bleeding, way too much bleeding. These, “start the clock.” Without medical
attention, even just self inflicted first aid, these will kill your character.
Usually these are sustained to limbs or the torso. Places where you can get
fairly deep without striking bone.
In the real world, blood loss will impair the fighter, slowing
them down, confusing them, making combat more difficult. This means their
defense (if they have one) will suffer, and it will be far easier for their
opponent to get through it with a kill strike. A blade through the throat or
chest, for instance. This isn’t always true in fiction, but it’s a function of
how the human body works that’s worth remembering.
If you’re asking, “is it plausible for a character to win a
swordfight with lots of tiny cuts?” Yes. If you’re asking, “is it plausible for
a character die in a swordfight with one or two deep, lethal wounds, and to be
otherwise untouched?” Again, yes. It really depends on the circumstances of the
I hope that clears things up some, and am genuinely sorry if
I’ve confused any of you by glazing over this. That one’s my mistake.
