Zip, I think you should pass on the razor blades. Really.
Side note: Back in my kids' teenage years, my yard was getting "farmed" by other kids. I fixed it several times but after some deep ruts on a rainsoaked lawn I called the cops, because we were pretty sure who it was.
Cops wouldn't pursue the lead. However, they DID suggest "lawn obstacles" of various sorts that would flatten tires. With the inop car as evidence, they could act.
They said I had to be sure the obstacles were well on to my property, at least 10 feet from the sidewalk and that I had better only have them out at hours when the public wouldn't be out. Like midnight to 0600.
This was suggested by our Police Department.
Kinda sounds like RPM's "booby trap" though, doesn't it?
