Abstract
The present invention provides a long-bladed bolster 1, comprising a substantially planar cutting body 2 having one edge formed as a blade 3 of sufficient length so that the blade 3 is arranged in use to be positioned substantially centrally on a concrete masonry unit (CMU) to enable the block to be divided without the bolster 1 requiring repositioning, the bolster having a striking body on a second long edge of the cutting body opposite to the cutting blade configured to receive repeated blows from a striking implement in use and to transmit these through the cutting body to the blade and the bolster having an integral handle that extends from the cutting body and/or striking body of the bolster substantially centrally along the length of the cutting body 2 and substantially orthogonally to the plane thereof.
Claims12
A long-bladed bolster, comprising a substantially planar cutting body having a plane and a first long edge formed as a cutting blade of sufficient length such that the blade is arranged in use to be positioned substantially centrally across a concrete masonry unit (CMU) block that it is mounted on top of to enable the CMU block to be divided without the bolster requiring repositioning, wherein the bolster has a striking body on a second long edge of the cutting body opposite to the cutting blade that is adapted to be struck repeatedly by a striking implement and transmits force therefrom through the cutting body to the blade;
- and the bolster has an integral handle that extends from the bolster at a location part-way along the length of the cutting body, the handle being spaced above the cutting edge and thereby not resting on the CMU block in use, and extending transverse to the plane of the cutting body, the integral handle being rigidly fixed in position on the cutting body and thereby moving with the cutting body when the striking body of the cutting body is struck;
- wherein the blade is at least 200 mm in length.
