Ironwood or Eastern hophornbeam
A deciduous tree and native to North America, the ironwood grows up to 40 feet tall. The leaves are acute, about 6 inches long, and finely serrated; the bark is gray-brown with narrow plates that flake off. Its slow-growing wood becomes very hard, which makes it useful for fence posts and tool handles. It is porous and dense, so it is also used in the construction of longbows.
