In math mode, how can I type a symbol that is the vertical reflection of \check{-}?

Question

This is what \check{-} looks like: $\check{-}$

I'd like to type something that is a vertical reflection of that: a "hat" accent below a horizontal bar. How can I put a hat accent below the -?

Answer 1

A poor man's solution using \scalebox:

\documentclass[border=5]{standalone}
\usepackage{amssymb}

\usepackage{graphicx}

\makeatletter
\providecommand*{\reflcheck}{%
  \mathbin{%
    \mathpalette\@reflcheck{}%
  }%
}
\newcommand*{\@reflcheck}{%
  \vcenter{\hbox{\raisebox{-0.65ex}{\scalebox{1}[-1]{$\m@th\check{-}$}}}}
}
\makeatother

\begin{document}
$\check{-}\reflcheck$
\end{document}

Answer 2

\documentclass{standalone}
\usepackage{mathabx}
\begin{document}
$\check{-}$ $\barwedge$
\end{document}

There's also an amssymb version where the wedge is taller.
