Is it possible to make the up/down harpoons bold? I tried \boldmath, \boldsymbol as well as bm package and they made no difference.

\documentclass{standalone}
\usepackage{tikz}
\usepackage{amsmath}
%\usepackage{bm}
\usepackage{amssymb}
\begin{document}
\begin{tikzpicture}
\node[thick,circle,draw,blue,minimum size=0.8cm] at (1,0) {$\boldsymbol{\upharpoonleft \downharpoonright}$};
%\node[thick,circle,draw,blue,minimum size=0.8cm] at (1,0) {$\bm{\upharpoonleft \downharpoonright}$};
\end{tikzpicture}
\end{document}

  • $\boldsymbol{\upharpoonleft \downharpoonright}$ works (notice curly braces), but result is poor (man bold) ... – Zarko Feb 23 '17 at 1:22
  • @Zarko Tried that and it made no difference on my system!? Missing braces was a typo, fixed – aiag Feb 23 '17 at 1:24
  • try to move amssymb before bm package: \documentclass{standalone} \usepackage{tikz} \usepackage{amsmath,amssymb} \usepackage{bm} \begin{document} \begin{tikzpicture} \node[thick,circle,draw,blue,minimum size=0.8cm] {$\boldsymbol{\upharpoonleft\downharpoonright}$}; \node[thick,circle,draw,blue,minimum size=0.8cm] at (1,0) {$\bm{\upharpoonleft \downharpoonright}$}; \end{tikzpicture} \end{document} – Zarko Feb 23 '17 at 1:30

Done here by manually overlaying 3 such non-bolded symbols in close proximity. Original shown for comparison...

\documentclass{standalone}
\usepackage{tikz}
\usepackage{amsmath}
%\usepackage{bm}
\usepackage{amssymb}
\usepackage{stackengine}
\def\boldupharpoonleft{\ensurestackMath{%
  \stackinset{c}{-0.06ex}{c}{.00ex}{{\upharpoonleft}}{%
  \stackinset{c}{0.00ex}{c}{.07ex}{{\upharpoonleft}}{{\upharpoonleft}}%
}}}
\def\bolddownharpoonright{\ensurestackMath{%
  \stackinset{c}{0.06ex}{c}{.00ex}{{\downharpoonright}}{%
  \stackinset{c}{0.00ex}{c}{-.07ex}{{\downharpoonright}}{{\downharpoonright}}%
}}}
\begin{document}
\begin{tikzpicture}
\node[thick,circle,draw,blue,minimum size=0.8cm] at (1,0) {$\color{blue}
  \boldupharpoonleft \bolddownharpoonright$};
\node[thick,circle,draw,blue,minimum size=0.8cm] at (2,0) {$
  \upharpoonleft \downharpoonright$};

\end{tikzpicture}
\end{document}
