Line cutters that may be incorporated into other items, such as garments or paddles. A garment that incorporates a line-cutting trim component allows a wearer to easily cut line or cord while fishing or engaging in other activities. The trim component includes a housing with an opening, and a line cutter partially extending into the opening. The trim component can be secured to the garment using a rivet, or sewn onto the garment. In another example, a paddle may incorporate a line cutter as part of a spring clip used to secure together the tubes of a multi-piece paddle.
