A mechanical broadhead having blades movable from a retracted mode to a deployed mode is provided including a generally external retainer element which holds the blades in the retracted mode, but also selectively releases the blades so that they can transition to the deployed mode. The retainer element can include a collar and one or more tabs. A blade can include a projection and/or a recess that is engaged by one or more tabs to secure the blade in the retracted position. The tabs can be paired and can define a retainer slot therebetween. The blade can be at least partially disposed in the retainer slot in the retracted mode and/or in the deployed mode.
