1. A wood processing device that includes an inlet, an outer unit and a cutting unit, where:
the outer unit includes a first outer unit face and outer unit sides at least partially surrounding an outer unit interior;
the inlet extends away from the first outer unit face;
the inlet is uppermost when the wood processing device is in use;
the inlet is configured to accept wood for processing and provide a path through the first outer unit face to the outer unit interior;
the cutting unit includes a cutting blade with a cutting blade edge; and
the cutting unit lies, at least partially, within the outer unit interior with the cutting blade immediately adjacent, and essentially parallel to, the first outer unit face;
wherein the wood processing unit further includes at least one movement device configured to move the cutting unit such that the cutting blade edge moves across an open end of the inlet wherein,
the cutting unit includes the cutting blade and a cutting unit base;
the cutting blade is adjacent the inlet;
the cutting unit base includes a support face and a pushing surface which are coterminous along one edge, such that, in use, the support face is the uppermost face of the cutting base and the pushing surface extends downwards; and
the cutting blade and support face are spaced apart by a distance WL;
characterised in that the wood processing device further includes a splitter that faces the pushing surface and the at least one movement device is configured to move the cutting blade across the open end of the inlet as it increases the distance between the pushing surface and the splitter, such that in a first position of the cutting unit, the cutting blade does not extend across the open end of the inlet and the pushing surface is adjacent the splitter and, in a second position of the cutting unit, the cutting blade extends completely across the open end of the inlet and the pushing surface is a maximum distance from the splitter.
