"getting shit done" and "Keeping you alive" are the MINIMUM any soldier can demand from his issued weapon.

doing the minimum to get by and never exceeding expectations is not the path to success.

aluminium receivers and a too-complex delicate mechanism which requires too frequent service is a flaw, the AR series of weapons are only acceptable when your forces have the logistical advantage. when the shit gets heavy and you have to call up the militia the AR is not nearly as Loser Friendly" as the Kalashnikovs and it's certainly not the best choice for a peasant levy on the long retreat to stalingrad.

the AR's dont suck, but for extended use in rough conditions without the readily available services of an armorer and plenty of spare parts, the AK's have no equal

Actually katanas if I remember correctly had a specialized plating on the edge that has a high tensile strength and hardness. The material formed what looked like sharks teeth at microscopic levels, which were found to be self sharpening. Furthermore, on top of that, the hardening, tempering and annealing process led to a blade that had a ductile core and a very brittle but hard edge.

If you know anything about material engineering, which you don't, you would know that metals with an RC hardness of about 56+ do not dull. That merely shatter, chip or fail if over stressed.

I ask you a very primitive material engineering question: How does a steel bandsaw blade cut the same steel material with no problem, over and over?
The answer is a steel blade that has a hardness sufficiently great.

I don't disagree that a blunt weapon would also suffice however

japanese swordsmiths used techniques of welding different varieties of steel to various locations. a fine katana was like a Jaguar E-type. magnificent to look at, fast and superb for it's intended use, but it spent more time in the shop than it did in battle.

there are NO self-sharpening blades on the planet, the closest you can get is Depleted Uranium Penetrators, and they do that through extreme velocity and heat, not through any magical "shark tooth" microfeatures or "Ki Energy Focus"

when facing a material harder than the blade, ALL blades dull. dulling is a function of wearing down the fine edge, not deforming the softer metal to a rounded profile. dulling is LOSS as is sharpening. thats why chefs dont like glass or stone as cutting boards. they wear your knives to a nub.

the brittle nature of the edge causes the CHIPPING i mentioned earlier. a fact that dismayed my Ultra Weeaboo eldest brother when he used my uncles' 200 year old wakisahi to chop the neck of a chicken instead of the usual hatchet. the neck bones of a barnyard CHICKEN chipped the edge. and this was not some superior, Ninja-Cyborg-Samurai chicken, it was a yardbird. the blade in question was also NOT a shitty replica, nor was it otherwise flawed. my uncle (a particularly skilled expert in aido) had used that same blade for years. the nature of the blades and their intended use is not conducive to effectiveness on bone, metal armor or other hard surfaces, particularly not in the inexpert hands of a weeaboo. that is why iado practitioners PRACTICE. to cut meat, and avoid bone. head lopping and limb severing is NOT a job for japanese swords. thats a job for an axe or a western sword. only the steadiest hands on the most precise angles can cut through bone without chipping the delicate and precise edge of a japanese sword.

finally, steel is not "steel" steel is a blanket term for a wide array of iron alloys. some are very hard, some are very soft. the teeth on a saw blade are always EXTREMELY hard, and i can tell you without doubt saw blades of all types DO also get dull, i know since i have sharpened them. with a file. which has teeth of the hardest steel for most saws, but diamonds for the most demanding blades. a metal cutting saw usually requires diamond sharpeners, where wood saws are less of a pain in the ass.

It's really too bad I can only feed S/PDIF coax, I'd love to hook up a real receiver and listen to some DTS-HD MA.

Firstly, you're wrong about plating being welding. Secondly you're wrong about the shark tooth like microscopic features, or I'm talking about the incorrect sword.
Thirdly, all you did with the rest of your post is arrogantly try to negate my scientific post (RC hardness of 56+. That's right, I'm an engineer and worked for years in a test lab testing materials.) with the general, layman version.

Expensive saw blades that are hardened, tempered, and case hardened again correctly do not dull, they chip off until the amount of missing cutting teeth, leading to loss of cutting production, justifies the purchase of a new blade.

Files are normally about 56RC and are HARD. They do get dull because they deal with filing other HARD (40+) metals for long period of time. Zombie flesh and bone is not 40RC+.
Furthermore, diamond coating is the best as diamond is the hardest material on earth.

Hardness is a characteristic that is defined by the molecular structure of the material, and can be modified very easily with high temperatures and cold, fast, liquid quenches, in regards to steel (yes again, an alloy of many metals including iron.)




edit:
In conclusion: as can be seen in the uploads, hardness and brittleness are proportional, while ductility is inversely proportional to brittleness. Furthermore, very hard materials do not dull unless used against another very hard material.

plating in an electrochemical process. japanese sword blades are not plated in anything. they are welded together as a brique before the forging goes to the anvil.


your "scientific post" was an attempt to use jargon to confuse the issue. your pretense that gross loss from chipping is distinct from microscopic loss (dulling) is not scientific. when placed under pressure against a harder material, ALL METALS DULL, some particularly hard metals chip and shatter easier than they dull but all blades can and do dull. this is distinct from breaking, chipping, or spalling.

wrapping your brainfart about eternally self-sharpening japanese swords embedded with microcrystalline shark tooth structures and other such hokum isnt convincing anybody you know what youre talking about. you know what DOES make people think you know what youre talking about?
knowing what youre talking about.

to sharpen (remove material to restore the edge profile) any blade from a saw's tooth to an axe's edge to a kitchen knife, to scissors requires a harder tool than the one you are trying to hone. you must remove deformed metal and reshape the edge to the poper angle, and smooth any chips. this is not a magic process, it's done by friction and abrasion in the right directions.

if you are dealing with saw blades who lose teeth till they stop cutting, youre using the wrong saw.
gap toothed saw blades dont cut precisely they tear, jerk and grab, this is unsafe for the worker wasteful of materials and damaging to the equipment. you would be kicked out of a lumber mill for proposing anything so stupid.
no metal working shop would give houseroom to a facilities engineer who thought saw blades could lose teeth and still be used.
no sawyer would let you touch his saw if you espoused that kind of madness.

where do the lost teeth go when they break off?

at what trajectory and at what velocity?

anyone who's ever seen a mill cut into a tree with an eco-nut's spike inside knows the whine of a saw thats about to unwind with lethal intent. most sawmills have metal detectors in the chute to find Greenpeace's additions to the timber and stop the blade before it gets into the spike. and not just to protect the expensive saw, but the flying metal bits can kill.

but then hey, how many teeth can your saws throw into the workspace before they become a hazard?

Yeah 62 is right. Anything north of 56 is really hard. I just picked 56 because thats about where hard steel blades are.

56 and 62 aren't very fa apart though. The scale is from 1 to 60+, with the majority of materials in the world being in the 20s-30s

Stopped here because again you are wrong. Do you understand what hardness means with respect to materials? Dulling is in the EXACT same category as chipping and failing.

Look up the Rockwell Hardness (RC), hardness testing method. I'm sure you've never done it. I have. You will come to understand it consists of using a HARD metal which doesnt dull, to poke a small divet in the testing material. The test would not work if the tester material deformed in conjunction of the testing material.

Again, do some research. Your belittling attempts are without any material backing; pun intended

I did, Logitech Z-5500.

You obviously know little about hooking up speakers and audio protocols.

Bare wire termination is better audio quality than banana or spade, also they can easily fail and degrade audio quality without obvious reason. Those two types are cosmetic and make setup "easier." The most common type people use recently for termination is solder-tinned.

http://en.wikipedia.org/wiki/S/PDIF

The I in S/PDIF is for interconnect. COAX used in receivers is a digital interconnect cable. COAX would be just fine for HD audio formats, but manufactures thought I'd be funny to screw the consumer and not update the receivers to allow S/PDIF COAX for HD audio. Instead, you're forced to use bullshit HDMI.

I would not presume the bolded.

My speakers would do poorly with those signal sources. I must first route them into my A/D converter on to the preamp and into the amp to generate something that'll drive my (unqualified, thus passive) speakers. I had to look up the Logitech model to discover that they are
a) active speakers, and
b) not a pair, but a 5.1 home theater array.
I'll spare you the snobbery two-channel audiophiles have for both home theater and digital signal (and active speakers but for a very few, very pricy exceptions), but you know it's there. cn

Some metals do not dull = FALSE
Chipping is different from dulling = FALSE, they are the same function on different scales of action.
Chipping is the same function as dulling = TRUE but he previously declared this to be false
Saws get dull by losing teeth = RETARDED AND DANGEROUS. flying jagged metal parts are not a product of normal use for any saw anywhere ever.

Bear,

Yes, the speakers are active. Hence why only the propriety pod can only be used. The amplifier is in the speaker. You would have to modify how your amp in the receiver drives the speakers, otherwise you'll blow its internal amp or other awesome things can happen.

There are plenty of good speakers which are very good for home theater. But those cost about $1,000 per speaker to rival mine.

$10,000 for a nice 7.1 setup just isn't worth it for me. I tested it in a sound treated room. That's how much it would cost before I heard a difference compared to mine.

Obviously we are talking about different swords because the one I am speaking of does have plating and does have a self sharpening effect, I'm positive as I've seen videos on it; the exact name of the sword slips my mind. And I've never advocated that a sword I could find would never dull, merely that a well made sword in the case of killing zombies, can go an entire life time without needing to be sharpened. What you're mistaking is that I've said that some materials never dull, they chip or fail before doing so. I presented stress-strain curves which demonstrates that very hard, brittle materials fail without warning, and have no deformation stage. It's basic material science. I fully comprehend that even the hardest of metals can be cut and dulled by diamond. But you have to understand the whole premise of the entire hardness argument is that much harder materials (56RC tool steel, steel blade) do not dull when used on much softer materials (human flesh and sometimes bone).
http://www.ami.ac.uk/courses/topics/0123_mpm/index.html
^^ even includes rockwell hardness for you. Cuz itz basik

Secondly, you don't understand metals or hardness. Did you look up the Rockwell Hardness test yet?

Thirdly I thought you were saying chipping is different than dulling as described in my previous post.

Fourthly, you obviously have never used a saw designed to cut metals. You are wrong again about saws losing teeth, and the fact that you believe that saws don't lose teeth is evidence of the fact that you have zero business in this discussion. Metal saw blades are replaced due to too many teeth being missing, thus resulting in a loss of cutting production. Metal saw blades DO NOT last long enough to be replaced because of any dulling they might obtain in its lifetime

I don't care how many books you read describing how metal works, until you have actually welded, heat treated, tensile tested, etc etc you don't know what you're talking about. It's plain as day as you don't even know how a basic metal saw functions.
