I have to make a single cut in a two inch thick basic concrete paving

usual health and safety reasons, and it doesn't seem worthwhile to hire
a wet cutter for a single slab, but I'd like to finish with as neat and
clean an edge as possible and previous experience suggests that
chiselling and hammering (even if the preliminary channels are made on
both surfaces and both edges) won't necessarily provide that.Â* Are there
any handy tips for a neater result?Â* Does the sharpness of the bolster
chisel make any appreciable difference?Â* Many thanks.

Cut all round using a diamond wheel. The snap. Then use the diamond
wheel at a slight angle to tidy the rough edge where the break was.
