ABSTRACT:
A grater and method for grating, wherein a grating panel is connected to a handle with a gripping portion aligned behind the grating surface back side below the top end and above the bottom end and in a common plane with the directional vector, the gripping portion further forming an angle with the downward directional vector, the gripping portion vector angle less than 90 degrees. It is preferred that the angle is selected to translate forces normal to and against the grating surface front side into compressive forces against a user's hand gripping the handle gripping portion. In one embodiment, the connecting means is a steel rod disposed along the panel edge portions and projects from the panel top normal to the planar panel. Some embodiments have stand elements to enable the grater to stand upon a work-surface.
