Draw striped arrowhead in tikz

Question

I want to draw an arrow with a striped arrowhead using tikz. I can't find anything in the tikz docs to do this.

\documentclass{standalone}
\usepackage{tikz}
\usetikzlibrary{arrows.meta}
\begin{document}
\begin{tikzpicture}[very thick,font=\sffamily\Large]
\draw[-{Latex[length=30mm,angle'=10]}] (0,-2) -- (0,3);
\end{tikzpicture}
\end{document}

I want to make something like the below figure. Black line with arrowhead that has evenly spaced orange/white stripes:

Answer 1

Here is an option using decorations.markings, although they can be improved to adapt to curves, in this case it does not, but you can look for examples with coils, however it is best to declare it as a style or pic so that you can do a lot with little code.

Answer 2

The inset is misused, it denoted the number of stripes (including the white/transparent ones). An even number will lead to the line ending at a white stripe.

Code

\documentclass[tikz]{standalone}
\usetikzlibrary{arrows.meta, bending}
\pgfdeclarearrow{
  name = Striped Triangle,
  defaults = {
    length  = +3pt 4.5 .8,
    width'  = +0pt .75,
    inset'  = +13pt,
    angle=+60:+2.7pt +3.6,
  },
  setup code={%
    \pgfarrowssettipend{0pt}%
    \pgfarrowssetbackend{-\pgfarrowlength}%
    \pgfarrowssetlineend{\dimexpr-\pgfarrowlength+.001pt}% visual things
    \pgfarrowsupperhullpoint{0pt}{0pt}%
    \pgfarrowsupperhullpoint{-\pgfarrowlength}{.5\pgfarrowwidth}%
    \pgfarrowssavethe\pgfarrowlength
    \pgfarrowssavethe\pgfarrowwidth
    \pgfarrowssavethe\pgfarrowinset
    \pgfmathreciprocal{\pgfarrowinset}%
    \let\pgfarrowstripedtrianglefrac\pgfmathresult
    \pgfarrowssave\pgfarrowstripedtrianglefrac
  },
  drawing code={%
    \pgfmathloop % could use qicker \pgfmathmultiply@ here
      \pgfmathmultiply{\pgfmathcounter-1}{\pgfarrowstripedtrianglefrac}\let\near\pgfmathresult
      \ifdim\pgfmathcounter pt=\pgfarrowinset \def\far{1}% just use 1 instead of n*1/n
      \else
        \pgfmathmultiply{\pgfmathcounter}{\pgfarrowstripedtrianglefrac}\let\far\pgfmathresult
      \fi
      \pgfpathmoveto{\pgfqpointscale{\near}{\pgfqpoint{-\pgfarrowlength}{+.5\pgfarrowwidth}}}%
      \pgfpathlineto{\pgfqpointscale{\far }{\pgfqpoint{-\pgfarrowlength}{+.5\pgfarrowwidth}}}%
      \pgfpathlineto{\pgfqpointscale{\far }{\pgfqpoint{-\pgfarrowlength}{-.5\pgfarrowwidth}}}%
      \pgfpathlineto{\pgfqpointscale{\near}{\pgfqpoint{-\pgfarrowlength}{-.5\pgfarrowwidth}}}%
      \pgfpathclose
      \ifdim\pgfinteval{1+\pgfmathcounter}pt<\pgfarrowinset\relax
      \edef\pgfmathcounter{\pgfinteval{\pgfmathcounter+1}}%
    \repeatpgfmathloop
    \pgfusepathqfill
  },
  parameters={\the\pgfarrowlength,\the\pgfarrowwidth,\the\pgfarrowinset}
}
\tikzset{>={Striped Triangle[fill=orange, angle'=30]}}
\begin{document}
\begin{tikzpicture}[ultra thick]
\foreach[count=\i] \ang in {0, 30, ..., 359}
  \draw[-{>[inset=2*\i-1]}] (0,0) -- (\ang:.7);
\end{tikzpicture}
\begin{tikzpicture}
\foreach[count=\i] \bendmode in {quick, flex, bend}{
\tikzset{yshift=-\i cm}
\draw [red!25,line width=1mm] (-1,0) -- (1,0);
\draw [red,line width=1mm,-{[\bendmode]>.>>}]
  (-1,-.5) node[right, black] {\bendmode}
  .. controls (0,-.5) and (0,0) .. (1,0);
}
\end{tikzpicture}
\end{document}

Answer 3

Somewhat kludgy. It would be easier to simply draw the shape, but if you especially want an arrow tip:

\documentclass{standalone}
\usepackage{tikz}
% ateb: https://tex.stackexchange.com/a/702116/
% cwestiwn Medulla Oblongata: https://tex.stackexchange.com/q/702111/
\usetikzlibrary{arrows.meta}
\usetikzlibrary{patterns.meta}
\begin{document}
\begin{tikzpicture}[very thick,font=\sffamily\Large]
  \draw[-{Latex[length=30mm,angle'=10]},line width=0pt,postaction={draw,-,shorten >=30mm-1.2pt,black,very thick},white,pattern={Lines[line width=2.5pt,distance=5pt]},pattern color=orange] (0,-2) -- (0,3);
\end{tikzpicture}
\end{document}

If it doesn't have to be an arrow tip, you can simply fill a triangular path. This doesn't rely on the background being white.

  \begin{scope}[xshift=10mm]
    \draw[shorten >=30mm-1.2pt,black,very thick] (0,-2) -- (0,3);
