Hello,

I have just completed a small retaining wall around a bed in the front of my house using one of the block systems from Home Depot (specifically PaveStone Natural Impressions Flagstone). The wall came out well overall, but I'm having issues cutting the capstones that sit on top of the wall. All other stones I have been able to split using a sledge hammer and chisel, but every time I attempt to split one of the capstones it cracks (and not along a scoring line!).

Does anybody have any experience or ideas about how to make cuts on these cap stones without mis-splitting them? Any help is very much appreciated!

Thanks,

Andrew
