I came late to this discussion. Why would anyone want to cut veneer
with a mat knife? The correct instrument is one of those little veneer
saws that have teeth on 2 edges. Veneer is usually cut in a stack with
the veneer saw using a batten for a straight edge. The purpose of this
is matched edges. The saw is ambidextrous. The teeth are sharpened just
like you would sharpen a knife. As many soft strokes as is necessary
are used to cut through the stack while the saw is held with the blade
flat against a thick batten so the angle of cut remains constant. You
can cut single pieces the same way.
If you are cutting a single piece of veneer, you can also use a very
sharp chisel that has been specially prepared for this purpose and is
used for no other purpose. It is also held flat against the batten and
used like a knife, or it can be used freehand for curves. This old
fashioned method is worth learning.
