Patent ID: 7210539

Claim:
A hole trimmer capable of removing peripheral material projecting inside a perimeter of a hole in the ground, said hole trimmer including: a severing mechanism with first and second substantially opposed cutting surfaces, configured such that said first cutting surface is incapable of passing through said perimeter, whilst said second cutting surface is capable of passing through said perimeter; an actuation mechanism capable of reversibly moving said first and second cutting surfaces towards and away from each other about a first longitudinal axis, wherein said first cutting surface has a substantially planar lower surface intersected by said actuation mechanism through an aperture impassable by the second cutting surface; and wherein, in use, said second cutting surface is capable of being inserted through said hole past said material until said substantially planar lower surface contacts said perimeter, whereupon, said actuation mechanism is activated to move said second cutting surface along said first longitudinal axis into abutting contact with the substantially planar lower surface of said first cutting surface, severing any material interposed therebetween.
