ABSTRACT:
A section of a first side of a blade between a cutting edge and a boundary line forms a cutting surface. An angle of a section of the cutting surface in the vicinity of the boundary line with respect to a hypothetical plane extending from the cutting edge and defined between the first and second sides of the blade is larger than an angle of a section of the cutting surface in the vicinity of the cutting edge with respect to the hypothetical plane. Therefore, the medical knife has an improved configuration such that the cutting performance of the knife is improved.
