to size. There's a few high end sheer cutters of that type are used in
picture making, maybe there's some that cut at 90°.

Seems the best way to me, if pricey. Cut nearly to length with a hand
miter saw, then shave to exact length with the Pootatuck Lion Miter
Trimmer. It does do squaring. The clones out there may also do
squaring. I think Grizzly distributes one.

They would work with wood, but that laminate is pretty tough stuff. It will
kill a carbide blade in short order. Do you think a trimmer can handle it?
