Hornbeam

The hornbeam (Carpinus betulus), also known as blue-beech, ironwood, and musclewood, is a small understory tree of the beech family (Betulaceae). The various common names come from the resemblance of the bark to that of the American beech Fagus grandifolia, the hardness of the wood and the muscular appearance of the trunk. The wood is not used much due to the small size of the tree, but its hardness has lent it to toolmaking and other crafts requiring hardness over quantity.
