comment Belay with a broken arm
"Hull's second best climber" (emphasis by me)? Then Hull's best climber must be you, right? ;-)

comment Is there a recommended safety standard for crampons?
Maybe as a side note: I have never read that crampons must meet any standard to be allowed to be sold. Climbing safety equipment (biners, ropes, etc.) may only be sold in the EU if they have the corresponding EN standard certification and have to be marked if they look like real climbing equipment but aren't certified. I did never hear such about crampons, so it may be allowed to sell them in the EU even without certification.

As far as I'm concerned, you cannot delete it, it can only be closed.

comment Is it a bad idea to dry clothes by the fire?
@LS OK, let's restrict it a bit: the rock will not explode just from putting typical undies on it" (corrected typo as well ;-) Of course I cannot say for sure if this is true for Jason's steel undies as well.

"a rock would definitely not explode"... well, they do, if you get the wrong ones: outdoors.stackexchange.com/questions/801/… and outdoors.stackexchange.com/questions/1407/… However, the rock will not explode just from putting your undies on them.

comment Best technique to sharpen a knife using a whetstone?
If you rub some metal over the roughest stone, the metal will have scratches that can easily be seen with the bare eye. To see the scratches left by the semi-rough side you will have to look very carefully, maybe with a magnifying glass. Both of them will make some scratching noise when worked with a metal. With the fine and super-fine one will at first glance not guess that it is able to do any harm to a metallic blade. Their noise is more dull, like rubbing two very smooth surfaces on each other.

comment Best technique to sharpen a knife using a whetstone?
It depends a bit of the grain sizes of the stone, whether you need the rough side at all. Basically such two-sided stones often come in two versions: one with a rough and a semi-rough side (grain sizes around some hundred grit) and one with fine and super-fine side (grain sizes in the thousands). With the rougher version, the rough side is normally only needed if the blade edge was damaged and has to be rebuilt by grinding bigger amounts of material until it is free of notches.

You forgot the bad practice of hooking your foot into the rope due to bad rope handling.

comment What are areas of the body which lose heat more quickly, and how can I reduce that loss?
I tend to contradict in 2 points: spots that feel cold first are not necessarily ones that lose the most heat but can also be areas that have low insulation and/or blood vessels close to the skin. Especially the wrists (also the veins at the thigh inside) are known to be well suited to manipulate body temperature sensation by "feeding" heat or cold into the body. This does not work because they are spots of heat loss but because they allow easy thermal coupling from the outside and the blood flow transfers the temperature applied there quickly to the body core.

comment Why some sleeping bags have four temperature ratings while others have only one?
possible, yes. At least you have to assume that the figures given are more or less useless or not comparable. As Ryley stated in the answer I have linked, they might write a rating at their bags which they expect protects them from being sued for, plus some error margin.

comment Arm compression sleeves for climbing
I still do, as the question was "Are there anecdotal or actual studies on the effectiveness of forearm compression sleeves for climbing?" Also you state that "Veins are through internal segments of the body and Arteries are in the outer segment" but according to my knowledge and Wikipedia it's reverse: "Veins are [...] often closer to the skin [than arteries]."

Sorry, but I don't see at all how that tries to answer the question...

comment How to walk as a roped party on a glacier?
@Vorac They should, but that requires that everyone notices immediately and physics is quite merciless here. Now imagine that the last one in the row stumbles and nobody sees that until they get hit by the tightening rope. At that point the fallen one might be stopped as he transfers his momentum to the other members which then are kicked off their feet and start to slide. Compare pp. 26 and sequential of the presentation linked in my answer.

comment How to prepare for a long rocky alpine route, which is unusual for me?
What's the typical ratio between climbing and scrambling in the routes you have in mind? Is it basically climbing with some easier sections every now and then or is it scrambling, that has some occasional climbing sections?

comment How to belay on top of a pitch
It's only available in German (I know that you understand it) and I don't have time to write a full-blown answer, but the bergundsteigen journal has an article about the pro's of belaying from your harness instead of from the anchor: bergundsteigen.at/file.php/archiv/2012/3/… Hope it helps somehow.

comment Ration or consume water?
This answer would need some more information to be useful. Things that spring to my mind are "How much water did he have?", "Where did that happen?", "How was the climate when this incident happened?". Even then the answer's endangered to be only anecdotal and possibly cannot be generalized to other people and situations.
