This mod makes the circular saw from the moreblocks mod available to mods residing in the MCL world (MineClone2/VoxelLibre, MineClonia).
You need to install the moreblocks mod as well. This is just a compatibility layer.
It just adds the saw including receipe. All blocks from the respective MCL game that are registered as slabs in that game normally are added to the saw.
Beware: If you use MineClone2/VoxelLibre, you may have to replace the screwdriver as the one it currently comes with is far too limited. MineClonia does not have this problem.
