一条蛇缠绕在竖直的匕首上，以白底粗黑轮廓线绘制，可用作纹身模板。有鳞的蛇张着嘴，露出尖牙和分叉的舌头，三圈缠绕在刃身上，匕首的护手两端有圆球，握柄呈螺旋状。可以更换蛇、武器或线条粗细，也可以用自己的颜色填充鳞片，做出自己的设计。

A traditional American tattoo stencil: a snake wrapped around a dagger, vertical and centred on a pure flat white background. Black outline only, in one even, bold line weight, as in the transfer an artist prints before tattooing. Every line is closed, continuous and crisp. No shading, no grey, no fill, no gradient, no hatching, no texture, no skin and no mockup. The dagger points downward, blade tip at the bottom. It has a long double-edged blade with a centre fuller line, a straight crossguard with rounded ends, a wrapped grip drawn as simple diagonal bands, and a round pommel. The snake's body coils around the blade and grip in three clear loops. It passes in front of the blade, then behind it, with small gaps in the dagger outline where the body crosses in front so the overlaps read cleanly. The snake's head rises at the top beside the pommel, in profile with its mouth open, two curved fangs, a forked tongue curling out, and a bold eye drawn as a ring with a solid-black-free open centre. The body shows a row of large, simple scale outlines (open U-shaped scallops) and a belly line of widely spaced plates. The tail tapers to a point and curls out near the crossguard. Keep all line gaps wide enough to survive as a tattoo at forearm size: the narrowest white gap is at least as thick as the line itself. Leave a clear white margin of about 8% on every side. There is no text, no border, and no extra ornament.
