1. A binding machine comprising:
a wire feeding unit configured to feed a first wire and a second wire to be wound on an object;
a cutting unit configured to cut the first wire and the second wire wound on the object; and
a binding unit configured to twist the first wire and the second wire wound on the object,
wherein the cutting unit comprises:
a pair of blade parts configured to sandwich and cut the first wire and the second wire therebetween, the pair of blade parts comprising a fixed blade part and a movable blade part configured to slide on the fixed blade part,
wherein the fixed blade part comprises:
a first butting portion against which the first wire from among the first wire and the second wire aligned in parallel is butted by relative movement of the movable blade part of the pair of blades, and
a second butting portion having an end edge portion, wherein movement of the movable blade part causes the second wire aligned in parallel to the first wire to be butted against the end edge portion, the end edge portion extending to a side of the second wire opposite to the first wire in a direction perpendicular to a moving direction of the movable blade part,
wherein the cutting unit has a step portion provided between the first butting portion and the second butting portion by recessing the second butting portion with respect to the first butting portion along the moving direction of the movable blade part of the pair of blade parts,
wherein the fixed blade part of the pair of blade parts comprises:
a regulation portion configured to regulate movement of the first wire in a direction from the first butting portion toward the second butting portion and provided between the first butting portion and the step portion, and
an opening through which the first wire and the second wire are configured to pass, and
wherein the fixed blade part is fixed relative to the first wire and the second wire in a radial direction of the opening, and
wherein the regulation portion is configured by providing a planar surface, which extends in a direction orthogonal to the moving direction of the pair of blade parts, between the first butting portion and the step portion.
