cut aerated concrete blocks?

[rosebuddy]

I am building a stair landing with lightweight concrete blocks, which means that I need to cut a 190*190*590 block lengthwise.

Which tool should I use for the smoothest cut? A worn-out handsaw?

Yes, it is possible, although difficult. It might be better to buy a new/cheap/sharp one for the purpose.

For larger projects, a special Lecasåg, Knäckblock, tigersåg with a special blade or alligatorsåg is used

I use a regular cutting wheel with a diamond blade (80 kr at Biltema). Cut as far as you can around and then pry with a regular screwdriver to split. Any unevenness is also sanded away with the diamond blade.

Maybe not the smoothest method but you avoid buying special tools.
