per Ezelius:
I made some more testing, and discovered that other knots (the adjustable Cawley hitch #1994, the taut-line hitch #1856 and the midshipman's hitch #1855) did not function at all on typical ropes for climbing of polyamide (nylon) because they are stiff and slippery.
All of these structures fall under the broad category of 'hitches'.
Within that broad category (ie hitches) - there are sub-classes:
[ ] load control hitches (eg #206 Crossing hitch is a load control hitch)
[ ] slide and grip progression hitches (eg for ascent/descent) - eg #1763 Prusik hitch is a slide and grip progression hitch
[ ] nooses (eg #409 Poachers noose and related #1120 Scaffold noose)
[ ] binders (eg a great example of which is the #1188 Constrictor hitch)
All hitches require a 'host'.
When the 'host' is removed - the hitch ceases to exist.
And this is a defining characteristic of all hitches...in that a 'host' is required.
I think of this in terms of a
symbiotic relationship between the host and client... in this case, it is
commensalism.
I tried on Edelrid Powerloc expert SP 7mm 14kN polyamide cord (EDELRID?s classic, very hard-wearing accessory cord with low elongation and excellent knotability) and Simond 6 mm 9 kN polyamide cordelette (suitable for making a Prusik or Klemheist knot, or any type of friction hitch for abseiling down). Actually the Ezelius eye was developed with the Simond 6 mm 9 kN polyamide cordelette.
One of the best all-round accessory cords (EN 564) is made by Sterling USA.
Particularly their 8.0mm diameter high strength cords.
You will find that the performance of all slide and grip progression hitches are highly dependent on the textile material they are formed from (which includes the interface between host and client).
I use Sterling accessory cord for virtually all my life critical applications... and so do many rope access and vertical rescue technicians.
Actually the Ezelius eye was developed with the Simond 6 mm 9 kN polyamide cordelette.
Again, the notional concept of the term 'eye' can be problematic.
It really depends on how 'technical' one wants to be with use of terminology.
As this is the IGKT and the fact that there are many 'enthusiasts' visiting, they tend to have a penchant for technical detail.
So again...a noose belongs to the broader class of 'hitches'.
And all hitches require a
host to form around. When that host is removed, the hitch ceases to exist.
In the specific case of a 'noose' (which is a type of 'hitch') - it is formed around its own SPart.
In other words, there is only one singular length or material (eg cord) - not 2 independent lengths of material.
A noose is its own
self host.
A noose has an adjustable 'eye'.
In the case of a slide and grip progression hitch, there is no adjustable eye (in fact, there is no eye at all).
Furthermore, this type of 'hitch' requires an
independent host (ie a completely separate length of material).
EDIT NOTE:
Most knot enthusiasts look to Ashley for definitions and technical understanding.
However, Ashley was not specific in his definitions.
As the world has evolved, knot tyers have evolved too.
More and more complex structures have been discovered and more technical deep understanding has been sort after.
I wish Ashley had defined all hitches as requiring a host.
And I wish that he further divided the broader category of hitches into distinct sub-classes.
The same goes for 'Bowlines', 'loops', 'turns', 'chirality', etc...
Its not defined with precision (in my view).
