Handcut paving sizing is done manually by chisel and hammer so edges looks more natural. It is used in landscaping and out doors and mostly in gardens.
The basic principle in splitting a paving unit is to ‘score’ the flag or brick all-round, where it is required to split. By a series of progressively stronger blows from a lump hammer onto the pitcher or bolster, the unit should split along the score-line. With flags, once a good score-line has been achieved all around, the pitcher/bolster can be set aside and a series of heavy blows directly from the hammer along the score-line on the back/bottom of the flag should persuade it to split along the score-line.
