How do I know when to choose between a Klemheist or prussik knot?
As already stated, these are very similar knots regarding their use. So there is not much that differentiates them from each other, or to other friction hitches. The advantage of the prusik is the "...

What is a bloquers?
It's what @imsodin said. Bloqueur is the french term for "blocker" in English. So when I talk about a bloqueur, I'm talking about blocking devices. The two that I use for ascending a rope are the ...

What is a bloquers?
I can only assume, that it derives from bloquer which is french for blocking. What the "c" is doing in there I have no clue - but then, I am not a native french speaker.

I use the (double) Fisherman's knot for such cases. It's easy to tie and has a clear and concise form (easy to check if done right). As already mentioned in nivag's answer, it can be hard to untie if ...

What is the difference between accessory cord and prusik cord?

How to arrange 2 Prusiks when ascending a rope?
I always ascend the other way around (foot-prusik above the chest prusik). This allows for a bigger movement with your foot and hence a bigger climb during your ascend.

I alternate between the double fisherman's (which everyone has already talked about) and the flat overhand. Lately I've been leaning towards the flat overhand.
