An improved cutter for minimizing deflection of the scissor blades during the cutting of a rigid slat, in particular the slats of a Venetian blind. The cutter includes a first scissor and a second scissor pivotally joined to each other at a fulcrum. The scissors further include blade portions suitable for cutting a slat when the scissors are closed. An engagement member is located at the distal end of each scissor. The engagement members are adapted to cooperatively engage one another as the jaw members are closing so that the engagement member of the second scissor is on top of the engagement member of the first scissor.
