Razor
Symbolizes precision, clarity, and the removal of unnecessary elements. A razor can represent the need to make clear decisions, cut away the superfluous, and focus on what is essential. It also carries connotations of danger and the potential for self-harm, reflecting the fine line between necessary pruning and destructive actions.
Themes: precision, clarity, decision, danger, focus
