Metal spike with a bent point (5)
I believe the answer is:
piton
'metal spike' is the definition.
'piton' can be an answer for 'spike' (piton is a kind of spike). I'm not certain of the 'metal' bit.
'a bent point' is the wordplay.
'a bent' is an anagram indicator.
'point' anagrammed gives 'PITON'.
'with' acts as a link.
Can you help me to learn more?
(Other definitions for piton that I've seen before include "Mountaineering tool" , "It helps the climber" , "What mountaineer requires" , "Spiked climbing aid" , "Climber's spike" .)
