Make him belt for finger-tip protection (7)
I believe the answer is:
thimble
'protection' is the definition.
(thimble is a kind of protection)
'make him belt' is the wordplay.
'make' indicates an anagram.
'him'+'belt'='himbelt'
'himbelt' anagrammed gives 'THIMBLE'.
'for finger-tip' is the link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for thimble that I've seen before include "digital screen" , "Cap used for protection when sewing" , "Caucus-race prize (Alice)" , "See 5" , "Digital protection" .)
