Thanks Dan - fair enough.
I retract my remark re “Your assertions”.
Probably should have typed something along the lines of…
“please add appropriate warnings that relying on slide and grip hitches for fall-arrest at a workplace is not recommended”.
(this of course assumes that we are both defining the term “Fall-arrest” in the same way, and assuming a minimum 100kg drop mass).
Anyhow, back to the original intent of this topic thread:
I still don’t know if my 2 originally presented slide and grip hitches are original…
Again, perhaps in the fullness of time I may gain more confidence with regard to making any claim of originality.
EDIT NOTE:
Since my original post, I have managed to acquire Bob Thrun’s book “Prusiking”.
I could not find my presented slide and grip hitches in that publication.
I did find a precursor to the so-called ‘Schwabisch’ hitch (via Thrun’s 3 turn illustration).
Thrun did not illustrate the 5 turn (ie 5 ‘coils’ around host rope) version (aka Schwabisch hitch).
It might be possible to extrapolate/surmise that Thrun knew he could add 1 more ‘wrap’ thereby making it 5 ‘turns’ (ie 5 coils encircling the host rope)…
…and I have no plausible reason to doubt that he might have done so.
But, from purely an evidence-based perspective, Thrun did not actually illustrate the 5 turn (Schwabisch) variation.
