The Trinity knot is rounded, asymmetric, unique and eye-catching. Slightly more adventurous than the Prince Albert, yet fairly simple once understood. All of the windings to create this knot are carried out using the thinner side and a longer tie is recommended if possible. More suited for non-professional occasions, such as parties or weddings this knot will amaze and baffle at the same time.
