'smoothly-crafted' originates from the combination of 'smoothly' and 'crafted', where 'smoothly' is derived from 'smooth', meaning 'even or without roughness', and 'crafted' from 'craft', meaning 'to make or construct with skill'.

'smoothly' evolved from Old English 'smōð', and 'crafted' from Old English 'cræftan', meaning 'to build or make'.

Initially, 'smoothly' meant 'without roughness', and 'crafted' meant 'made with skill'. Together, they evolved to describe something made with elegance and precision.
