Something a rock climber might make with one hand (4)

I believe the answer is:

knot

(Other definitions for knot that I've seen before include "Tie; a cluster" , "Could be a granny or a sheepshank" , "Hard round cross-grained piece in wood" , "Nautical measure" , "1 (nautical) mph" .)

I've seen this clue in The New York Times.
