Rope !! (solve it)

Rajeev is trapped atop a building 200m high. He has with him a rope 150m long. There is a hook at the top where he stands. Looking down, he notices that midway between him and the ground, at a height of 100m, there is a ledge with another hook. In his pocket lies a Swiss knife. Hmm... how might he be able to come down using the rope, the two hooks and the Swiss knife?

Cut the rope into a large 100m piece and a small 50m piece.

tie the small rope to the hook and create a bow-line hitch at the loose end of the small piece.

thread the 100m piece through the loop so that the midpoint is at the loop and hangs down by 50m on each end.

twist the two ends around each other like a candle wick and descend to the ledge.

untwist the two ends and pull the 100m rope out from the loop. the rest should be easy.

Apparently it is an abomination to use the Swiss knife without mentioning its name.
