Embodiments of the invention include methods and devices for securing a suture, graft, or other material to tissue with an anchor. The anchor of some embodiments includes an eyelet through which the suture, graft, or other material may be passed and mechanisms for selectively engaging the suture, graft, or other material through the eyelet. The mechanisms of some embodiments may also reinforce the anchor to provide a strengthened anchor to withstand actions such as impacting the anchor during insertion or applying bending stress to the anchor.
