The Handshake at U+1F91D is a People & Gestures emoji showing two hands clasped together, used to mean agreement, cooperation, greeting, or a completed deal. As an emoji character, it carries its meaning through a familiar social gesture rather than through a spoken language or writing system. In everyday messages, it most often signals mutual understanding: “we’re agreed,” “deal,” “good working with you,” or “thanks for partnering.” Businesses, teams, and community groups use it in posts about partnerships, negotiations, sponsorships, hiring, customer relationships, and collaboration. It also appears as a friendly greeting or sign of respect, especially in professional or semi-formal chats where a heart or thumbs-up may feel too casual. In social media captions, it can mark solidarity between people or groups, as in support for a shared cause, alliance, or reconciliation after conflict. On many platforms this emoji supports skin-tone modifiers for each hand, so it may appear as a single default color or as mixed skin tones depending on the keyboard and system. That variation is meaningful in contexts about inclusion, representation, or cross-cultural cooperation.
