A surgical scalpel (32; 50; 100) comprising: a body (52; 160) having a first end, which is a forward end, and a second end; said body (52; 160) comprising a beak (58; 20; 120) extending from said first end in a first direction away from said second end, and an extension (60; 122) extending from said first end in a second direction away from said second end, a triangular notch being defined between said beak (58; 20; 120) and said extension (60; 122); and a surgical blade (92; 110; 162) imbedded in said body (52; 160) and having a sharp edge portion (94; 112) extending between said extension (60; 122) and said beak (58; 20; 120) and positioned to cut tissue passing between said beak (58; 20; 120) and said extension (60; 122); wherein said beak (58; 20; 120) and said extension (60; 122) are configured to allow a forward push of the scalpel to cut tissue while holding the second end of the scalpel, wherein said beak (58; 20; 120) extends further from the first end than said extension (60; 122); wherein said beak (58; 20; 120) has an upper surface and a lower surface that is rounded along said first direction to smoothly pass over and separate tissues during a cutting process and terminates in a rounded point at an intersection of the upper surface and the lower surface; characterised in that the lower surface of the beak is curved towards said extension (60; 122), so that the lower surface (30; 124) insures an adequate separation between said blade and the underlying tissue during said cutting process and further in that said rounded point is configured to push slightly upward a tissue wall during said cutting process; and wherein said body (52; 160) is a plastic body having a flat shape. a body (52; 160) having a first end, which is a forward end, and a second end; said body (52; 160) comprising a beak (58; 20; 120) extending from said first end in a first direction away from said second end, and an extension (60; 122) extending from said first end in a second direction away from said second end, a triangular notch being defined between said beak (58; 20; 120) and said extension (60; 122); and a surgical blade (92; 110; 162) imbedded in said body (52; 160) and having a sharp edge portion (94; 112) extending between said extension (60; 122) and said beak (58; 20; 120) and positioned to cut tissue passing between said beak (58; 20; 120) and said extension (60; 122); wherein said beak (58; 20; 120) and said extension (60; 122) are configured to allow a forward push of the scalpel to cut tissue while holding the second end of the scalpel, wherein said beak (58; 20; 120) extends further from the first end than said extension (60; 122); wherein said beak (58; 20; 120) has an upper surface and a lower surface that is rounded along said first direction to smoothly pass over and separate tissues during a cutting process and terminates in a rounded point at an intersection of the upper surface and the lower surface; characterised in that the lower surface of the beak is curved towards said extension (60; 122), so that the lower surface (30; 124) insures an adequate separation between said blade and the underlying tissue during said cutting process and further in that said rounded point is configured to push slightly upward a tissue wall during said cutting process; and wherein said body (52; 160) is a plastic body having a flat shape.
