如何在latex中用tikz画一把“圣剑“

因出题需求，需要一把圣剑的图片，苦于难以寻找，于是决定直接动手绘制。绘制效果如下： 代码附上：

\documentclass[a4paper, 10pt]{book}
\usepackage{fancyhdr}
\usepackage{geometry}
\usepackage{framed}
\usepackage{ulem}
\usepackage{amsmath}
\usepackage{mathpazo}
\usepackage{tikz}
\usepackage{calc}
\usepackage{xcolor}
\usetikzlibrary{calc}
