# Tip of a distorted and curved vector

Supposing to have this MWE,

\documentclass[a4paper,12pt]{article}
\usepackage{amsmath,amssymb}
\usepackage{tikz}
\begin{document}
$a\Bcirc b$, $\blacktriangle, \blacktriangledown$
\end{document}


Is it possible to properly distort black triangles to have a distorted and curved effect on the circumference like the image below?

I.E. Is there any strategy or package to distort the black triangle symbol?

A first approach with arrows.meta and bending tikz-libraries.

\documentclass[a4paper,12pt]{article}
\usepackage{tikz}
\usetikzlibrary{arrows.meta}
\usetikzlibrary{bending}
\begin{tikzpicture}
\def\R{0.750cm}
