I’ve seen this a few times but how possible is it really to deflect a bullet with a bladed weapon?redironsword
Nope. Or, at least, not intentionally.
There’s two problems: Physiology and Physics.
First, your reflexes aren’t that good. I don’t mean, you personally, I mean it’s well beyond human reflexes. Depending on the bullet, it’s likely traveling faster than the speed of sound, meaning, your brain isn’t wired up to see the bullet itself, to say nothing of intentionally parrying it.
Even if you could, you’d need to accelerate your blade to superhuman speeds to get it into position. Even if you could, you can’t see where the bullet will be.
So, without superpowers, no, not at all.
Incidentally, this is also why you can’t dodge bullets. You also can’t dodge sniper fire because the bullet will get there before the gunshot, if you were wondering. Same problem applies if you wanted to parry a marksman’s bullet.
This is where physics screws you. Strictly speaking, a bullet could deflect off a blade, or other metal surface. This does happen. So far as it goes, bullets will sometimes deflect off of bone or shatter on impact. So, that’s another possible outcome, turning the bullet into a shower of shrapnel still pointed in the general vicinity of everywhere the, “lucky” blade wielder was standing.
The other possibility is that the blade itself fails, turning into shrapnel that sprays your blade wielder. Now, figuring out exactly what would happen depends on a lot of factors, including the exact positioning of the blade, it’s condition, design, also of course the bullet and it’s trajectory. So, I can’t just say, “it’d explode into a shower of shattered metal functioning as an impromptu bomb in their face.” Then again, a bullet isn’t likely to hit their blade in the first place.
Finally, even if this does go to plan, the bullet will still deliver a lot of force to the blade, ruining it. There may be some weird edge case with a super-alloy weapon, and of course, characters with superpowers start to break all kinds of rules, but realistically, that blade is going to suffer some damage in the process.
So, no, you can’t parry a gunshot, but you might be able to accidentally deflect the bullet. Which could be far worse depending on how that plays out.
