Lot of decent vids on youtube about hinge cutting. Seems to make sense in certain applications - winter browse, channeling game, creating possible bedding and such.

There is a guy that seems to be the main authority on this, he has posted here (bioactive) and is a regular on the qdma site. You should look at his vids.

EDIT - The man's name is Jim Brauker. Google/youtube his name or "extreme dear habitat." Given the way the rest of this thread has gone, I should point out that he is extremely safety oriented.
