Gunblade models don't need to be so extra...

I always the the vibration was supposed to act as a stunning effect upon impact, allowing you to get a meatier hit that just with a sword. Though, that makes it more of a bashing weapon, hmm.

The way I picture it, is akin to this video but with a bit more "blast" to it.

Rather than anything escaping or shooting out, it's just being compound into an explosion right there on that section of the blade. I also imagine there's some momentum physics that would go into it, if you got it to blow back, you''d likely swing it in such a way that you could use the recoil as a heavier strike. Off topic tho.... Our next step in the shadowbringers relics look promising at least glow-wise.... It's showing good signs of us getting the "good" Lionheart.

OP I feel the same way about SMN/SCH books.
Simplicity is good, but I'm not gonna hold my breath for it in a JRPG.

The idea of a gunblade's cartridge exploding and creating vibrations in the blade that increase it's cutting power is based off the idea of the vibroblade, a type of weapon commonly found in science fiction, although real world adaptions of the concept have been developed for use in scientific and medical applications.

A vibroblade is basically a bladed weapon, usually being a knife or sword, on which the blade is vibrated at an extremely high frequency.
The science behind how it works is that the high frequency vibrations of the blade cause the blade to move back and forth in incredibly fast but microscopic movements, creating a concentrated sawing motion with the blade. Since the edges of blades are more effective at cutting when drawn across what is being cut as opposed simply being pushed against it, the vibrating of the blade and the accompanying sawing motion that it creates increases the cutting force of the blade.

Now realistically, the explosion from a bullet cartridge is nowhere near enough to cause vibrations in a large metal blade in the way a vibroblade works since the vibrational frequency would be much lower and the energy would dissipate into whatever was being cut very quickly since the vibrational force occurs in only a short burst instead of being sustained. However, while the vibrations in the blade would be much lower in frequency and energy compared to a vibroblade, the additional movement of the blade from the vibrations during cutting would likely result in the cut not being as precise and clean, leaving a not as deep but more ragged wound which could end up being more deadly.

As for recoil on a gunblade similar to a regular gun, there probably would not be any or if there was it would likely be greatly diminished.
Recoil when shooting a gun is basically Newton's Third Law of Motion (for every action there is an equal and opposite reaction) playing out.
When a bullet is fired from a gun, the force of the bullet cartridge explosion propels the two parts of the bullet cartridge, the casing and the bullet itself, apart in opposite directions. The bullet is expelled from the gun at high velocity, while the force applied to the casing which is still within the gun is transferred to the gun itself and this is what recoil is.
In the case of a gunblade, the force of the bullet is transferred back into the gunblade as it strikes the blade to cause the vibrations and so you end up with opposite forces pushing on the gunblade in opposite directions which would likely nullify each other out. There could potentially be a slight jerk in the gunblade as the cartridge would likely start to exert the backwards force on the gunblade immediately while there would be an almost imperceptible delay before the bullet strikes the blade and exerts a forward force on it, counteracting the backwards force already applied.

LOL none of this matters cuz they don't mention in FFIV's lore they do the vibrating thing anyways lmao. Anybutt....

I'm hype for the finished product of this now. I didn't think it would show signs this early.

Um ... okay. I never said I was speaking specifically about FFXIV gunblades. You and others were discussing Garlean gunblades versus Bozjan (FFXIV) gunblades versus FFVIII gunblades for almost a whole page.
Some people expressed confusion about the mechanics behind how the original gunblade in FFVIII worked in regards to the whole vibrating blade aspect, notice I quoted someone else along with you, and so I gave the basic explanation.

I know, I'm just repeating thread derailed lol.

I like most of the gunblade models currently in the game. I know a lot of people think they look too small, but I think they really give off the feel of a powerful weapon you can easily carry into any situation, a sort of "fantasy tactical" look. I am happy that they've drawn from firearms from all eras to design the "gun" parts, allowing to look as modern or as historical as you want from revolvers, flintlocks, and the more archaic horizontal revolving mechanism the shinryu gunblade has.

I think the one I like the least right now is the gunblade of light. I like the idea behind it, but I find the second blade to be awkwardly spaced too far from the first, making it look like a bayonet for a weapon that already is a blade. That said, I'm not against experimenting with new designs, as we've seen in this thread that opinions as to what constitute a good looking gunblade are varied.

I would like to see the big gunblade from the original concept art for the job from the artbook make it into the game at some point though

THANK YOU, SOMEONE FEELS HOW I DO ABOUT THE GUNBLADE OF LIGHT TOO LOL.

[MorionQ]

Cool stuff.

Ah, thank you. I was not aware of this trope and this was explained very well!



Honestly, I feel like the entire concept of Gunblades is intentionally extra AF in design. From the past characters who have used them to the basic concept itself, it’s cool factor with layers of anime-protag cheese. It’s dumb, but fun.

I’m partial to the choice to repeat FFVIII’s version of Gunblades, but I do like the heavier, machine gun style from the above concept art. While it reminds me a bit of those chainsaw guns from the Gears of War series, that bulkier weapon looks more tank-like.
