  We present a summary of the splinter session "Sun-like stars unlike the Sun"
that was held on 09 June 2016 as part of the Cool Stars 19 conference (Uppsala,
Sweden). We discussed the main limitations (in the theory and observations) in
the derivation of very precise stellar parameters and chemical abundances of
Sun-like stars. We outlined and discussed the most important and most debated
processes that can produce chemical peculiarities in solar-type stars. Finally,
in an open discussion between all the participants we tried to identify new
pathways and prospects towards future solutions of the currently open
questions.
