Spike with a bent point? (5)
I believe the answer is:
piton
'spike' is the definition.
(piton is a kind of spike)
'bent point' is the wordplay.
'bent' indicates an anagram.
'point' anagrammed gives 'PITON'.
'with a' acts as a link.
(Other definitions for piton that I've seen before include "Metal spike used in rock climbing" , "something used when climbing" , "Peg driven into rock in mountain climbing" , "Mountaineering tool" , "Spiked climbing aid" .)
