There's a person named Michael from the Wild flower Tool company who is doing a tutorial on telescopic head shears for gardening.  He demonstrates the several features of the shears such as extendable handles.  He is standing near a big hedge in a garden.  He shows how to use the shears by cutting off some of the branches of the hedge.  He then extends the handles of the shears to show how far he can reach hard to reach places on top of the hedge.
