I love hinge cutting. It's so rewarding if done properly. The best places to hinge cut are deer bedding areas and along field edges (this is considered "edge feathering").
Keep in mind, deer won't just bed anywhere you hinge cut. Make sure you are doing it in area deer prefer to bed. Such as on the tips of points. I would cut more on the south side of slopes as this is where deer bed in the winter and have the least amount of cover.
Deer and small game really benefit from edge feathering. This gives cover to small game and browse for the deer. Plus, deer prefer to transition from the woods to a food plot through some type of cover. If you hinge cut 20-40 yards off the plots the deer will stage in the cuts and feed on the browse before hitting the fields. Ideally, you will want to cut about 75% of the trees the first 10-15 yards, then 50%, then 25% to give the deer different levels of edge and a smooth transition to your plots.
Additionally, hinge cutting can be an excellent tool to create funnels around your stands. Deer are lazy, they will take the path of least resistance. Keep that in mind.
I would'nt recommend running around your woods hinge cutting everything. Although this will provide instant cover and food, the new shoots and sprouts will shade the understory. In areas outside of what I mentioned above, I prefer to treat the undesirable trees with herbicide. The sun will create much more desirable browse from the ground than a hinge cut tree.
Also keep in mind that turkeys will avoid thick, hinge cut areas unless they are nesting.
