The present invention is a dual function transfer tray that can be used for either a scalpel or a suturing needle holder with suturing needle. A scalpel slot is formed in the bottom of a relatively deep set of sloped walls. A suture needle cavity is formed above the first slot. However, at a mid-section of the scalpel slot and the half-cylindrical suture needle cavity are opposing and deep V-shaped cutaway sections in the sidewalls with a flat floor section between them. A user need never have to focus their attention for more than a split second to discern the location of the mid-section of the transfer tray. The user's thumb and forefinger are aimed at the V-shaped sidewall openings to grasp a midsection of a supported surgical sharps. The scalpel slot and half-cylindrical suture needle cavity are set relatively deep with respect to top edges of the transfer tray and the to form an open tray to prevent a user from being inadvertently injured by a scalpel blade or a suture needle. In addition, the scalpel cannot be placed in the scalpel slot unless it rests on one of its longitudinal edges, preferably the same one as that of its blade edge. Thus, a user grasping the mid-section of the scalpel handle in the cutaway and flat floor section picks up the scalpel in a ready-to-use position.

A protective sheath for a disposable surgical scalpel includes at least three modes of operation, (i) a protective mode, (ii) an open mode, and (iii) a permanently locked mode. In the open mode, a locking strip of the scalpel handle resides in one opening of the sheath to keep the sheath substantially immobile during use of the scalpel blade. In the protective mode, the locking strip resides in a second opening of the sheath to keep the sheath substantially immobile when the scalpel blade is not in use. In the permanently locked mode, a button connected to the sheath is depressed into the second opening and engages the locking strip, thereby preventing the blade from being used and allowing the scalpel to be safely disposed.
