  We study the electronic structure of a double-twisted few layer graphite
(DTFLG), which consists of three few layer graphite (FLG), i.e. ABA-stacked
graphene multilayer, stacked with two twist angles. We consider two categories
of DTFLG, alternately twisted case and chirally twisted one, according to the
rotation direction of the two twist angles. We show that, once the middle FLG
of DTFLG is not thinner than trilayer, both kinds of DTFLG can remarkably host
two pairs of degenerate moir\'{e} flat bands (MFBs) at $E_f$, twice that of the
magic angle twisted bilayer graphene (TBG). The doubled MFBs of DTFLG lead to
doubled DOS at $E_f$, which implies much stronger correlation effects than the
TBG. The degeneracy of MFBs can be lifted by a perpendicular electric field,
and the isolated MFBs have nonzero valley Chern number. We also reveal the
peculiar wave function patterns of the MFBs in the DTFLG. Our results establish
a new family of moir\'{e} systems that have the much larger DOS at $E_f$, and
thus possible much stronger correlation effects.
