Sawbones
Slang name for a surgeon and, in particular, an orthopaedic surgeon (who may have 'sawed bones' on the battlefield in days gone by).
The term 'sawbones' has been in use for many years, as in: 'What, don't you know what a Sawbones is, Sir,' enquired Mr.
Weller; 'I thought everybody know'd as a Sawbones was a Surgeon.' (Dickens, Pickwick Papers, 1837).
