The Trinity knot is, hands down, one of the most popular necktie knot styles out there. This slick knot has a three-way symmetrical look that get its influence from the Celtic Triquetra, a design used as a religious symbol during the ancient Christian era. The pattern “hold hands” at a center point, producing a very conversational effect. I can see how a guy can be a bit intimidated by the Trinity at first glance, but it’s one of the boldest tie knots you can learn and surprisingly not as hard as it looks (that’s what she said). The trick is, unlike most tie knots, it is tied somewhat loosely. This can take some getting use to and can be a little frustrating at first, but with some patience the Trinity knot can be mastered.
