Itinerant almost steals King Tut's head ornament (7)

I believe the answer is:

trinket

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

'ornament' is the definition.
(I have seen 'Small ornament' mean 'trinket' so perhaps 'ornament' could also mean 'trinket')

'itinerant almost steals king tut's head' is the wordplay.
'itinerant almost' becomes 'trine' (I can't justify this - if you can you should give a lot more credence to this answer).
'steals' indicates putting letters inside.
'king' becomes 'K' (abbreviation for king in chess).
'head' indicates taking the first letters.
The initial letter of 'tuts' is 't'.
'trine' enclosing 'k' is 'trinke'.
'trinke'+'t'='TRINKET'

Can you help me to learn more?

(Other definitions for trinket that I've seen before include "Knitter (anag.)" , "Trifle" , "Cheap showy jewellery" , "Small piece of jewellery of little value" , "Ornamental item of little worth" .)
