A fixed-blade knife includes a unitary blade having an implement, a tang, and a pivot region between the implement and the tang. The unitary blade is disposed between a pair of parallel and spaced-apart side pieces that pivot to cover or expose the implement. In the pivoted position wherein the implement is exposed, the side pieces form part of the handle that is used to grasp the knife. A locking structure locks the side pieces in a selectable position, and a limit structure prevents overrotation of the side pieces.

A lens injector includes a thin sheet-like lens glide member, mounted upon a tapered knife, that maintains a wedge-shaped opening in the cornea upon withdrawal of the knife. The lens is thereafter advanced under the cornea by a plunger in the injector that maintains the lens in place as the injector device is removed. A multiple point blade knife may simultaneously make a set of several small, connected incisions. The fact that each blade has only a limited depth means that the resulting wide incision can be created without the need to penetrate deeply into the cornea, as would be necessary with a single-point blade of the desired width. This is especially beneficial for creating Z-shaped incisions, which become self-sealing when internal pressure pushes the inner layer against the outer layer. This shortens the process significantly, which then results in less trauma to the eye and streamlines the entire procedure.

A fixed blade knife, includes a handle, and a blade, coupled to the handle. The blade has a tang received within the handle.

A retractable blade knife with an opening assisted mechanism has a handle, a blade mounted in the handle, an extending assembly mounted between the blade and the handle. At least one detent formed at a spine edge of the blade. The extending assembly has a positioning frame, a slider mounted beside the positioning frame and attached to the blade and a spring attached to the positioning frame and the slider. The positioning frame has a resilient rod selectively abutting the spine edge and a proximal end of the blade. The blade should be pushed manually a certain distance to allow the spine edge of the blade to push a rear end of the resilient rod outwardly. When the detent of the blade and a lock protrusion of the slider both depart from the resilient rod of the positioning frame, the spring may further pull the slider to move together with the blade to stretch out the blade. Thus, the spring helps the blade to be extended quickly and the extending assembly also prevents the blade from being retracted or extended accidentally. Therefore, the retractable blade knife with an opening assisted mechanism is used safely and conveniently.
