Any router that isn't carbide will dull real quick.
If you use a carbide one you would probably need automated movement to
prevent it breaking, or one that is very large and wasteful.
A shear will not dull noticeably even after many cuts. I can still cut
paper with the hand shear i used for years. Not with the lever shear, but
that never did cut paper.
