A he-man's edgy side (3)

I believe the answer is:

hem

I'm a little stuck... Click here to teach me more about this clue!

'edgy side' is the definition.
'hem' can be an answer for 'side' (thesaurus). I'm unsure of the 'edgy' bit.

'a he-man's' is the wordplay.
'man' becomes 'm' (M is an abbreviation for male or masculine).
'he'+'m'='HEM'

Can you help me to learn more?

(Other definitions for hem that I've seen before include "Sewn edge to fabric" , "Finished edge of a piece of cloth" , "Express hesitation" , "Sewn border" , "may attract attention" .)

I've seen this clue in the Evening Standard.
