Is there a way to keep chilled cookie dough from flattening while cutting it?

Question

Whether using a serrated or straight knife, this seems to be a problem. I end up reshaping them by hand on the cookie sheet so they are round instead of oval.

Is there a way to slice the dough to prevent this flattening?

PS: I should clarify that the chilled dough is in a roll shape.

Answer

Two things.

Use a sharper knife. Don't chop, but slice gently. Let the weight of the blade do the cutting.
