In heraldry, the bow knot is a symbol of unity, loyalty, remembrance, and binding commitment, valued for the way its tied form suggests connection held securely in place. Unlike more martial charges, the bow knot carries a gentler but still meaningful symbolism, often representing family bonds, alliance, affection, or faithful service. It may appear in coats of arms, badges, or decorative heraldic elements to mark attachment to a cause, a house, or a personal relationship, and in some traditions it can also suggest honour bestowed through service or favour.

Knots more broadly have a long history in heraldry and emblematic art, where they stand for permanence, continuity, and the strength created by joining separate parts into one. The bow knot is especially effective in armorial design because it is both elegant and symbolic, offering a visual sense of order, grace, and deliberate connection. In heraldry, it serves as a refined emblem of ties that endure, expressing the idea that loyalty, kinship, and remembrance can be among the strongest bonds a coat of arms is meant to preserve.
