I believe the answer is:

mac

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

'as' is the definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.

'worn by a master craftsman initially?' is the wordplay.
'worn by' means one lot of letters goes inside another.
'initially?' indicates taking the first letters (I've seen 'initially' mean this).
The first letters of 'master craftsman' is 'mc'.
'a' placed inside 'mc' is 'MAC'.

Can you help me to learn more?

(Other definitions for mac that I've seen before include "laptop?" , "Coat - computer" , "A Gaelic son, often in name" , "Waterproof coat (colloq.)" , "PC" .)
