Diamond wiresaw, surely? I though diamonds didn't like chains as
there was too much shock loading. Even then, those are usually kept
for concrete with hard aggregates as brickwork will succumb to a far
cheap wheel.

I sometimes use a chain morticer with a carbide chain that costs an
indecent amount. I imagine these make even that look cheap.
