The LCD Panel vs. The Crossbow
Ev!LOnE was one of several readers to point out an interesting LCD stress test: "ASUS recently came out with Asus LS201 — a TFT monitor with a protective panel made of crystal-sapphire. What I didn't imagine was the amount of punishment that thing can take. Apparently some Ukrainians shared the same concern and went for a test." Translation not necessary, but some clues about the narration would be appreciated in comments.
Too big for the blender.
One such product is the Asus LS201 -- a TFT monitor with a protective panel made of crystal-sapphire. Our Asus rep says not only is it scratch-proof, but it's also 'punch-proof'. We were dared to hit it as hard as we could and told it wouldn't break.
Never ones to shirk from a challenge, we formed an orderly queue and gleefully punched the hell out of our first LS201 sample. Unfortunately one of our punchers was wearing a ring, and the offending jewellery left a 2cm scratch on the supposedly scratch-proof monitor.
Asus sent us a replacement and politely asked us to remove any jewellery before we let rip. We duly obliged, but instead of emerging unscathed, the LS201 developed a small, unidentifiable blemish below the protective panel. It wasn't a scratch or a dent -- it looked more like a small piece of fluff.
Our verdict: the LS201 will not shatter into a million pieces when punched (don't try this at home). It's therefore ideal if you're the type of person who likes to attack inanimate objects, or just drop blameless pieces of technology. But it's most definitely not scratch-proof -- we don't care what the stickers say.
The tips could have easily been bent by that shot, even by a weak crossbow as it appears was used here.. if they were first annealed. From the glance at the quarrels in the video, they appeared to have been subjected to high temperatures at some point. http://en.wikipedia.org/wiki/Annealing_(metallurgy) Perhaps even made from lead or babbitt, from another look at the video. Hard to tell.. Regardless, though.. I am impressed by this demonstration.
-Troll, Flamebait, and Offtopic are NOT equivalent to disagreement.
First, it's Russian he is speaking, despite the commercial being Ukrainian. The only thing worth translating he says at about 1:00 : "The thing is, that the coating of the monitor is out of the ordinary. In theory, it should withstand extreme stress, some even say it is bullet-proof. That's exactly what we wanted to check. The monitor has survived the shoot, but since the manufacturer gave it to us for tearing apart, we decided to literally kill it. For this we have a crossbow and crossbow arrows." In the end he concludes that this is probably the most resilient monitor in the world.
There is no sig.
Medieval weaponsmiths were paid to produce stuff that could punch through scale mail. That? It'd be a terrible bruise.
There was no such thing as "scale mail". Scale armor and maille are two different things. Do some more research and try again.
Scratch sapphire? With sapphire being #9 on the Mohs hardness scale... not going to happen (except with a ruby, another sapphire, or of course a diamond). Maybe silicon carbide if you believe a certain wiki. Incidentally, the "transparent aluminum" tag isn't too far off. Never thought about sapphire during, what was it, ST-4 ?
insert pithy comment here
Ultrahard Fullerite and aggregated diamond nanorods are harder than diamonds.

No kidding. A friend of mine had an LCD ruined by his kid...he shot an Airsoft gun at it. That plastic pellet bounced off too, but it did a number on it. Cracked glass, leakage, etc. He was pretty pissed.
Hardness isn't everything. You can break a diamond into pieces with a hammer, even if the diamond is harder than the steel. Hardness means basically that you can't scratch a sheet of diamond with a steel bolt.
My english is sow-sow. Sowhat?
