Marking/cutting concrete blocks technique please

[Dodgyrog]

I'm wasted here

Not totally wasted .... Miss Galore and myself had a giggle over that

To the OP - how many blocks do you have to cut? I find just scratching with the end of a tape measure then tap away with a bolster and hammer, gently for the first few taps and then more heavy and you usually get a clean break - but wondering if you are like me and go for millimetre perfect when it's not always necessary

just to round out this thread the chisel technique works perfectly no more faffing around sharpening pencils constantly, thanks to all who helped out. I'm going to burn the pencils now.
