'skillfully-handled' originates from the combination of 'skillful' and 'handle', where 'skillful' means 'having or showing skill' and 'handle' means 'to manage or deal with'.

'skillful' changed from the Old English word 'sceolful', and 'handle' from the Old English 'handlian', eventually forming the modern English term 'skillfully-handled'.

Initially, 'skillful' meant 'full of skill', and 'handle' meant 'to touch or feel with the hands', but over time, it evolved into its current meaning of 'managed with skill'.
