a blade assembly including:
an inner blade including inner blade teeth;
an outer blade including outer blade teeth oriented parallel to the inner blade teeth, wherein the inner blade is supported relative to the outer blade such that the inner blade is moveable, and wherein heat is generated on the outer blade as the inner blade moves; and

a thermal insulative barrier including:
open pockets located between an inner surface of the thermal insulative barrier and a surface of the outer blade, the open pockets receiving ambient air that circulates in the open pockets to thermally insulate the thermal insulative barrier;
a plurality of projections on the inner surface of the thermal insulative barrier and extending toward the outer blade, the plurality of projections providing structural support to the thermal insulative barrier when pressed against a surface of the outer blade; and
a plurality of channels located on the inner surface of the thermal insulative barrier and connecting the open pockets between the inner surface of the thermal insulative barrier and the outer blade.
