1. A propelled cutter comprising:
a) a cutter body comprising:
i) a first side; and
ii) a second side;
iii) a front;
iv) a back;
v) a bottom;
vi) a top; and
vii) a vertical axis extending from said bottom to said top when in an upright position;
b) a fixed blade coupled to the cutter body;
c) a foot extending from said bottom of the cutter body and configured to guide a material to be cut over the foot and across the fixed blade;
d) a drive input device coupled with a drive input extension that is coupled with the cutter body and with a drive assembly, said drive assembly comprising:
iii) a first propulsion gear configured on the first side of the cutter body and having a rotational axis;
iv) a first transfer gear configured on the first side of the cutter body and having a rotational axis and being movably attached and movably engaged with the first propulsion gear to spin the first propulsion gear;
v) a second propulsion gear configured on the second side of the cutter body and having a rotational axis;
vi) a second transfer gear configured on the second side of the cutter body and having a rotational axis and being movably attached and movably engaged with the second propulsion gear to spin the second propulsion gear;
wherein the first propulsion gear is driven by the first transfer gear to spin to move said material to be cut across the fixed blade to cut said material; and
wherein the second propulsion gear is driven by the second transfer gear to spin to move said material to be cut across the fixed blade to cut said material.
