Yes a very useful tool - for infesting an area with intense noise pollution. This toy is a favourite with Joe Bloggs who is everywhere cutting bricks etc to cover what is left of green space - with concrete. We have such Joes around here - in a flood plain! Yes cretin inhabitants moan like hell about how they hate their houses being flooded, and with their other face race, lemming-like, work to cover the land so rain cannot run off. Their stupidity is enormous. Just what overloaded drain/sewers need, extra water to cope with!
Due to such things (and this crazed lunacy of mass house building due to no immigration controls) the flooding is already getting worse. Roads I know for 30 years are now flooding due to the above lunacy.
Anyway, this rant was supposed to be about those damn brick cutters. In my world, the oiks would have to measure the sizes needed (yes every brick) and then go do the cutting at some soundproof factory where they can deafen themselves to their hearts content. Virtually EVERY DAY around here is heard the sound of these horrible devices just so idiot people "must have" a paved front garden "just like the neighbours", Our kids will grow up never having seen a piece of grassland.
