Shaving tool

Claim 2

An instrument for use in extricating ingrown hairs from skin tissues, comprising: a handle; a curved extension attached to said handle, said curved extension having a proximal portion and a distal portion, said distal portion comprising a tapered blade terminating in a sharp point, said tapered blade having a noncutting upper surface adapted for lifting but not cutting the ingrown hairs, said tapered blade further comprising an upper concave surface having radius R, two lower convex surfaces, and two upper side surfaces, all of said surfaces intersecting at said point.

Claim 3

An instrument for use in treating PFB by lifting and extricating an ingrown hair, comprising: an elongate handle; a tip atached to said handle, said tip comprising a distal portion and a proximal portion, and wherein said distal portion comprises a curved and tapered blade having a noncutting upper surface adapted for lifting but not cutting the ingrown hair, said blade further comprising an upper concave surface of radius R, two lower convex surfaces, said lower convex surfaces intersecting in a crown, and two upper side surfaces, each one of said upper side surfaces intersecting said upper concave surface and a different one of said lower convex surfaces, wherein said upper concave surface, said lower convex surfaces, and said upper side surfaces all intersect and terminate at a sharp point.

Claim 4

An instrument for use in treating PFB by lifting and extricating an ingrown hair, comprising: an elongate handle; a tip atached to said handle, said tip comprising a distal portion and a proximal portion, and wherein said distal portion comprises a curved and tapered blade having a noncutting upper surface adapted for lifting but not cutting the ingrown hair, said blade further comprising an upper concave surface of radius R, two lower convex surfaces, said lower convex surfaces intersecting in a crown, and two upper side surfaces, each one of said upper side surfaces intersecting said upper concave surface and a different one of said lower convex surfaces, wherein said upper concave surface, said lower convex surfaces, and said upper side surfaces all intersect and terminate at a sharp point.

Claim 5

An instrument according to claim 2, wherein said proximal portion comprises an upper concave surface of radius R, said upper concave surface of said proximal portion being continuous with said upper concave surface of said blade, a lower surface, and two side surfaces.

Claim 6

An instrument according to claim 3, wherein said handle comprises an upper surface, a lower surface, and two side surfaces, said lower surface of said handle being substantially coplanar with said lower surface of said proximal portion of said tip, and said side surfaces of said handle being substantially coplanar with the respective side surfaces of said proximal portion of said tip.

Claim 7

An instrument according to claim 4, wherein said point is disposed at a predetermined distance above the plane which includes said upper surface of said elongate handle.

Claim 8

An instrument according to claim 5, wherein said predetermined distance above said upper surface of the handle exceeds about 0.06 inches.

Claim 9

An instrument according to claim 2, wherein said crown which includes the intersection of said two lower convex surfaces has a radius R.

Claim 10

An instrument according to claim 2, wherein said instrument is made of nontoxic and hypoallergenic plastic.

Claim 11

An instrument according to any one of claims 2, 3, or 7 wherein said radius R exceeds about 0.3 inches.

Claim 12

An instrument according to claim 1, wherein said handle comprises an elongate member having a generally rectangular cross section, said elongate member having an upper surface and a lower surface and two side surfaces.

Claim 13

An instrument according to claim 10, wherein one end of said proximal portion of said curved extension comprises a cross section identical to said cross section of said handle.

Claim 14

An instrument according to claim 1, wherein said two lower convex surfaces intersect, forming a curved crown.

Claim 15

An instrument according to claim 12, wherein the radius of said curved crown formed by the intersection of said two lower convex surfaces is substantially equal to R.

Claim 16

An instrument according to claim 1, wherein said instrument is made of nontoxic and hypoallergenic plastic.

Claim 17

An instrument according to any one of claims 1 or 13, wherein R exceeds about 0.3 inches.

Claim 18

An instrument according to claim 10, wherein said point is disposed at a predetermined distance above the plane which includes said upper surface of said elongate member.
