Default Cutting concrete blocks

I will obviously need to cut concrete blocks - I will be using the
'medium density' blocks for external walls with no rendering.
[At least I think the normal ones are described as 'medium density' - it
does beg the question as to what 'dense' blocks are.]

I see there are some hand saws to cut blocks although most (but not all)
of them say they are for lightweight blocks.
I have some difficulty visualising cutting the 'medium density' concrete
blocks with a hand saw.
Is this practical?

Using Google I have seen various descriptions of block cutting methods.
Scoring with a cold chisel all round the block seems to be a very slow way.
Is scoring all the way round with a small angle grinder a good way to
prepare blocks for cutting?


I just use a bolster and a club hammer.

If I want a pretty result, I don't use concrete blocks ;-)
