I found it was the initial pushing of the blade into the matboard that would deform the blade -- then as one starts the cut the blade would straighten out and give one a curved start. By starting the cut early while drawing the cutter forward keeps the blade from deforming. Works with 4 and 8 ply.
That is a great sounding suggestion. I never tried that. I do have my technique down with the dexter/logan combo and can make perfect cuts. But I have quite a lot of logan blades to use.
