Quite right - the Prusik is ABOK #1763 (the Klemheist is illustrated as #1762 though again not named).
Although this can get debatable vis-a-vis
what IS a *knot*? issues:
i.e., although the geometry is present, Ashley gives no hint really of the
use of ascending a rope--of grip & release & re-grip ... repetition (arguably
an even greater gulf between the Crossing Knot and Mezzo Barcaiolo ("Munter")
hitch workings. --just to highlight how the
What is ...? issue can have
some effect.
