  We report that the twisted few layer graphite (tFL-graphite) is a new family
of moir\'{e} heterostructures (MHSs), which has richer and highly tunable
moir\'{e} flat band structures entirely distinct from all the known MHSs. A
tFL-graphite is composed of two few-layer graphite (Bernal stacked multilayer
graphene), which are stacked on each other with a small twisted angle. The
moir\'{e} band structure of the tFL-graphite strongly depends on the layer
number of its composed two van der Waals layers. Near the magic angle, a
tFL-graphite always has two nearly flat bands coexisting with a few pairs of
narrowed dispersive (parabolic or linear) bands at the Fermi level, thus,
enhances the DOS at $E_F$. This coexistence property may also enhance the
possible superconductivity as been demonstrated in other multiband
superconductivity systems. Therefore, we expect strong multiband correlation
effects in tFL-graphite. Meanwhile, a proper perpendicular electric field can
induce several isolated nearly flat bands with nonzero valley Chern number in
some simple tFL-graphites, indicating that tFL-graphite is also a novel
topological flat band system.
