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.
