Why are High Frequency Blades a thing in so many pieces of sci-fi battle fiction?
As far as I understand it, the blade is supposed to vibrate on a very small scale, but very quickly, under the power of an AC current. But isn't this a bad idea for cutting flesh? Modern Turkey Carvers are fucking shit compared to just a well sharpened and freshly honed conventional blade, and serration in general is only good for bread.
Am I missing something on why knifefags love the concept of HF Blades? I could understand if the current heated it up or had some taser-like effect, but what's with the strict HF Blade as a power weapon?
>>30066137
The cuts are rough and jagged as hell, but they do cut better than conventional blades.
>>30066137
It's really just a way to make a knife futuristic anon.
>Turkey Carvers are fucking shit compared to just a well sharpened and freshly honed conventional blade
IIRC, vibro blades in Star Wars for example oscillate at like 30000 times a second or some bullshit. Turkey carvers aren't anywhere near that.
The theory in-universe is generally that the HF lets them cut through things they otherwise wouldn't be able to. Evangelion is particularly dumb about this with the progressive-knives.
>>30066137
Turkey cutters don't vibrate at gigahertz frequencies, nor are they sharpened to a molecular scale. In theory you could make a blade that is capable of cutting through most everything, which is what the HF blades of fiction are.
>>30066168
>Turkey carvers aren't anywhere near that.
But they're still complete garbage, because serration sucks for cutting things that don't have a crumb to them and are fairly firm, like flesh (cooked or living).
I figured the HF action is supposed to give a chainsaw-like quality, but that's no good against anything that isn't either exceptionally porous and collapsible, like wood, bread, plastic foams, etc.

Doesn't EVA have weird religious ghosts and literal angels by the classical interpretations and stuff, too, though?
>>30066137
Sci-fi shit is written by 'numbers is hard' arts students that did journalism and womens studies at university.

Okay since you didn't seem to understand me the first time.
It's Scifi. 90% of the shit you see. In Scifi. Is psuedo science bullshit. If you keep trying to put logic into Scifi, you're going to have a bad time and hate yourself.
Has anyone ever tried to build one of these things, even for testing? Or does it work out to being an RF hazard from a particularly shitty antenna?
>>30066217
>Doesn't EVA have weird religious ghosts and literal angels by the classical interpretations and stuff, too, though?
Yes. The word "apotheosis" gets chucked around as part of the fucking things' bootup sequence in one episode.

b-but isn't the point and fun of sci-fi exactly that you're supposed to put lots of effort and logic into extrapolating future tech
even 40k has some sensible answers to its particularly insane non-supernatural elements, let alone a series that (used to be) as full of mil-porn as Metal Gear Solid.

Maybe 80 years ago with shit like Ray Bradbury or HG Wells.
They needed SOMETHING to give swords a mcguffin scifi power.
You know that one movie with ScarJo that was all "HUMANS ONLY USE 10% OF THEIR BRAINS WHAT IF YOU USED 100%?!"
It's like that. Everyone knows it's bullshit, it's a setup for something else and nothing more.
>>30066325
>Everyone knows it's bullshit
You be amazed how many people believe the 10% of your brain thing.
>>30066309
>Ray Bradbury, HG Wells
>Realism
Nigga, did you read either of them?
>>30066325
Same kind of military-retardation of people getting on a fantastically huge space ship, travelling squillions of light years to some exotic planet... then some faggot whips out a sword to kill the natives with.
>>30066350
Have you, while keeping in mind the time period they were written in?
>>30066325
that movie was the Clickbait Genre, not SciFi
>>30066351
didn't they do the literal opposite of this in Stargate? some native whips out an electro-spear or whatever, owns a log, and then one of the Stargate human crew whips out a p90, snipes the rope another training log is hanging from, then shreds it to pieces with the remaining rounds in the mag
actually hold that thought; i found it. pretty close to what i remembered. just in reverse:

SOME sensible answers. Lots of shit there works like the infinite improbability drive: you use normal physics in a clever way to manipulate something that defies logic.
>>30066836
I was thinking more like lasguns and dreadnoughts and tau tech in general -- a lot of it is reasonable, just not feasible right now.
Le Evin Le Warp Kaos Lol :^) stuff is all trash, of course, but it's not like railguns aren't a thing. And Tau Markerlights are basically just IR flares/laser designators.
>>30066217
Serration is bad for cutting flesh? Unless you're using some sharp as sin knife to begin with I feel like serration is useful for cutting up chicken or such,.
>>30066675
Wow he really acts like a fag there.
>>30067032
>Unless you're using some sharp as sin knife to begin
Buy just a simple steel honer. I guarantee, it'll be your most used tool in all of your house. Yes, even more than that KA-BAR you have on your waist 24/7.
A sharp conventionally bladed knife is way better than a serrated one for cutting anything that doesn't crush a lot under pressure -- which especially includes flesh. Even moreso on cooked flesh.
The feeling of slicing a piece of meat or a soft vegetable with a sharp knife is unmatched. It's even better than the smell of cordite.
>>30066137
Electrosurgical blades run at at least 500k Hz and can cut skin and muscle pretty easily but they are horrible at cutting fat and bone.
>>30066261
The High Frequency band starts at about 28 MHz and if you could see the radio waves at the frequency they would be 10 meters (32 feet) from crest to crest. For practical reasons antennas at these frequencies must be least 1/4 the size of the 10 meter wavelength.
Also the transmitter would need a peak envelope power of more than 50W with a duty cycle of at least 50% in an enclosed space.
>>30067209
>The High Frequency band
stopped reading there, that refers to radio and has nothing to do with cutting power
>>30066137
Its a way to spice up a edged weapon in sci-fi without being a light saber ripoff while sounding more realistic.
>>30067294
Frequency isn't "radio"-only you retard
Frequency means a repeating event per time unit
>Fucking your mum with 2 thrusts per second
A frequency!
>>30067209
Do you understand what this thread is about? It's about swords, not radio transmission.
>>30067385
Actually, HF, MF and LF, and so on refer directly to radio frequencies, not frequencies in general. Mostly because what's subjectively high or low differs a lot based on the application and materials involved.

No. It's total fucking nonsense and I guarantee you absolutely nothing from that shit series of stories will ever come to pass.
>>30066137
i'm quite sure this technology it's used in surgery, it suppose to cauterize the wound automaticaly or something
>>30066229
Umm. No.
>>30066271
If want "realism" read works by proper scientists not writers.
Example: http://www.rifters.com/real/Blindsight.htm
>>30066137
>Modern Turkey Carvers are fucking shit
They operate at ~60Hz, the HF blades in MGR are something like 200MHz IIRC.
>>30066137
It's basically an upscaled fantasy variant of an existing surgery tool.
https://en.m.wikipedia.org/wiki/Harmonic_scalpel
Theory is that the HF vibrations on the edge of the fictional blade add stress to the contact area.
Similar to sawing motions with a steak knife; moving the blade back and forth to cut through a piece of meat is more effective than trying to push it through.
For anything that's not a cleaver or axe.
>>30066200
¨the real limit to cutting is material displacement, not sharpness
>>30066229
No
>>30067044
You would if you had a full-auto P90.
>>30071184
So a HF blade would need to function more like a saw than a blade, removing material as it goes through.

Oh man, I gotta re-read those. It's been too long.

It's always easy to say that most of the boards are worthless and shit in regards to their respective topics. Like, no one sane goes to /v/ to get actual info on video games, or /his/ for history. But none approach the level of uselessness and counterproductivity of /lit/. It's seriously like it's inhabited solely by people who have a couple dozen books under their belt, and half of those were assigned reading through highschool.
>>30066229
Kek journalism major reporting. I seriously hate stories that involve numbers... it's not hard I just take longer with fact checking maths
>>30068149
But we have early forms of combat drones (tau), exo-suits (power armor), nerve splicing of amputated limbs into mechanical limbs (dreadnaughts). Hell, people are already starting to seriously consider genetically modifying humans to survive lethal environs like space. Yeah they just plan for space travel right now but you know what that means (motherfucking. Spress. Marines)
Warhammer 40k is our future except there is no Warp and all the other races will be created by modifying standard humans to live on different planets.
I wish I could live to see it.

Prog-knives are pretty much like mono-molecular edged chainsaws.

This.

Either /lit/ is retarded or I had an unnaturally good high school education
>>30066137
I always assumed the point was to create so much friction along cutting edge that it would superheat the surface being cut and pass clean through like butter. I think raiden's sword was actually explained this way ingame at one point, and i know they explained the Evangelion prog knives somewhere
