Cutting paving without a powered saw?

With a bolster chisel and a club hammer, section by section along your line of cut.

You can be unlucky from time to time, and you get an odd one that goes off at an angle, but it works for Mr Sunny most of the time 

That sounds a bit like an echo.

True.

Make sure you wear safety goggles 

Sorry,  I should have said that really. Thanks for this Yorkie 

All sorts of cuts can be done with a hammer and bolster.

When I moved into my first house I had no patio or anything outside my back door, just mud, I also had no money it being my first house.

My dad worked in the paving and tarmacing business at the time and they had just lifted a load of thick Paving slabs from BBC TV centre, these were transported to my house and one of the pavers came to lay them for me.

I watched him lay them, he did every single cut with a hammer and bolster, even ones where he had to cut a corner out.  I watched as I couldn't help as they were big heavy slabs that I couldn't even lift.

Hope it all goes well -- remember the soft surface, as Ivor said. Important!

Mr Sunny has reminded me that his fist slab just cracked as the soil he was resting on had a biggish stone in it.

He used our allotment towel folded up after that
