One who cobbers or cobbles; someone who mends shoes or does rough repair work.
From cobbler, with the suffix -er added (one who does the action), dating back to Middle English when cobblers were shoemakers and repair people.
The term 'cobbler' once meant someone who did poorly done work (hence 'cobbled together'), but somehow cobblers became respected artisans despite the insult embedded in their job title!
