wherein the first and second protruding stops protrude into the opening of the third plate of the first attachment device and prevent the first knife from rotating more than one hundred and eighty degrees with respect to the second knife, after the second knife is attached to the first knife.

9. The apparatus of claim 1 wherein

the first knife has a clip.

10. An apparatus comprising:

a first knife;

a second knife;

wherein the first knife includes a first attachment device;

wherein the second knife includes a second attachment device;

wherein the first attachment device and the second attachment device can be attached to each other to attach the first knife to the second knife;

wherein the first attachment device and the second attachment device can be detached from each other to detach the first knife from the second knife;

wherein the first attachment device is comprised of a first plate having an opening;

wherein the second attachment device is comprised of a protrusion attached to a second plate;

wherein the protrusion of the second attachment device cart be inserted into the opening of the first plate to attach the first knife to the second knife;

wherein the opening in the first plate of the first attachment device has a first substantially rectangular portion, a substantially circular portion, and a second substantially rectangular portion;

wherein the protrusion can only be inserted into the opening of the first plate when the second plate is at an angle with respect to the first plate,

and wherein after the protrusion has bean inserted into the opening of the first plate, and while the protrusion resides in the opening of the first plate, the second plate can be put into alignment with respect to the first plate by rotating the second plate with respect to the first plate until the second plate becomes aligned with respect to the first plate.

11. An apparatus comprising:

a first knife;

a second knife;

wherein the first knife includes a first attachment device;

wherein the second knife includes a second attachment device;

wherein the first attachment device and the second attachment device can be attached to each other to attach the first knife to the second knife; and

wherein the first attachment device and the second attachment device can be detached from each other to detach the first knife from the second knife;

wherein the first attachment device is comprised of a first plate having an opening;

wherein the second attachment device is comprised of a protrusion;

wherein the protrusion of the second attachment device can be inserted into the opening of the first plate to attach the first knife to the second knife;

wherein the second attachment device is comprised of a second plate attached to the protrusion;

wherein first and second rotating balls are attached to the first plate, so that the balls can rotate but remain in the same position;

the second plate includes a first ball opening and a second ball opening; and

wherein the first rotating ball can be inserted into the first ball opening and the second rotating ball can be inserted into the second ball opening in order to lock the first knife in a first position with respect to the second knife.

12. The apparatus of claim 11 wherein

the second plate includes a third ball opening and a fourth ball opening; and

wherein the first rotating ball can be inserted into the third ball opening and the second rotating ball can be inserted into the fourth ball opening in order to lock the first knife in a second position with respect to the second knife; and
