a handle having a gripping portion and an attachment portion, the attachment portion including a pivot member having an at least partially spherical surface; and
a cartridge removably attached to the attachment portion and supporting at least one cutting blade;
wherein rotation of the at least one cutting blade is enabled by a clevis comprising two opposed legs having spaced-apart ends, the pivot member of the attachment portion pivotably held between the spaced-apart ends of the two opposed legs of the clevis; and
a stop extending from and above the at least partially spherical surface of the pivot member and configured to limit rotation of the cartridge when the cartridge is mounted on the attachment portion;
wherein the stop is configured to limit rotation of the cartridge by interacting with a relief portion of at least one of the two opposed legs of the clevis; and wherein the two opposed legs of the clevis have respective holes formed therein, and wherein the spherical pivot member is pivotably held between the holes formed in the two opposed legs of the clevis.
11. A razor, comprising:
a cartridge supporting at least one cutting blade;
a handle having an elongate gripping portion and an attachment portion at one end of the handle, the attachment portion supporting a pivot member providing a removable attachment to the cartridge;
wherein the pivot member includes an at least partially spherical surface and is configured to be held between spaced-apart ends of two opposed legs of a clevis; and
a stop protruding from the at least partially spherical surface of the pivot member and configured to limit rotation of the cartridge when the cartridge is mounted on the attachment portion;
wherein the stop is configured to limit rotation of the cartridge by interacting with a relief portion of at least one of the two opposed legs of the clevis; and wherein the two opposed legs of the clevis have respective holes formed therein, and wherein the spherical pivot member is pivotably held between the holes formed in the two opposed legs of the clevis; and
wherein the two opposed legs of the clevis have respective holes formed therein, and wherein the spherical pivot member is pivotably held between the holes formed in the two opposed legs of the clevis.
[ 15. The personal grooming apparatus of claim 1, wherein the holes formed in the two opposed legs of the clevis are through holes.]
[ 16. The personal grooming apparatus of claim 1, wherein the holes formed in the two opposed legs of the clevis do not entirely perforate the two opposed legs.]
[ 17. The personal grooming apparatus of claim 1, further comprising another stop extending from and above the at least partially spherical surface of the pivot member and configured to further limit rotation of the cartridge when the cartridge is mounted on the attachment portion.]
[ 18. The razor handle of claim 6, wherein the holes formed in the two opposed legs of the clevis are through holes.]
[ 19. The razor handle of claim 6, wherein the holes formed in the two opposed legs of the clevis do not entirely perforate the two opposed legs.]
[ 20. The razor handle of claim 6, further comprising another stop protruding from the at least partially spherical surface of the pivot member and configured to further limit rotation of the pivot member.]
[ 21. The razor of claim 11, wherein the holes formed in the two opposed legs of the clevis are through holes.]
[ 22. The razor of claim 11, wherein the holes formed in the two opposed legs of the clevis do not entirely perforate the two opposed legs.]
[ 23. The razor of claim 11, further comprising another stop protruding from the at least partially spherical surface of the pivot member and configured to further limit rotation of the cartridge when the cartridge is mounted on the attachment portion.]
