Shears

Shears are a planned tool mentioned by Jeb on Twitter. It will be able to quickly remove wool blocks, and will be the only reasonable way to get wool from sheep. It has also been confirmed that shears will be a legit way of obtaining leaf blocks (which may be used for garden decoration like hedges). Sheep, leaves and TNT are confirmed uses for shears, as well as an unknown 4th use. Jeb also announced that they would defuse TNT.
