Dagger is a Frame that features two sharp protrusions on each side, akin to a double sided Hit. Such a shape is meant to increase Burst Attack during Disc-to-Layer contact. However, due to most Burst Performance Tips being of the same or very similar heights, such contact is rare. While the round shape of the Frame may imply high Life-After-Death, the protrusions warp the perimeter and reduces Life-After-Death potential compared to Cross and Glaive. Furthermore, compared to Frames such as Bump and Meteor, Dagger is too light to aid in Attack combinations.
Due to Dagger's low weight, warped perimeter and ineffective gimmick, it is outclassed by many other Frames in the Metagame.
As such, Dagger is recommended for collection purposes only.
