'old kind of sword' is the definition.
The answer and definition are not the same part of speech.

'old model stuck cut by' is the wordplay.
'old' becomes 'o' (abbreviation).
'model' becomes 'T' (Ford Model T car).
'stuck' becomes 'wedged' ('wedge' can be a synonym of 'stick').
'cut by' indicates putting letters inside (some letters cut their way into a word).
't'+'wedged'='twedged'
'o' placed into 'twedged' is 'TWO-EDGED'.
