another easy way to frag some lps colonies is to buy a hand grinder( angle grinder?) and put a 4" diamond disk on it for cutting tiles or stones.
on the under neath of the corals your going to cut several lines horizontally and vertically about half way through the rock or skelaton creating a grid of lines .
put a flattop screwdriver in one of the lines on back and twist , this will break the channel that you cut and then a new razor blade can be used to cut the flesh.
this works great and was my method before buying a bandsaw.
since all the work is actually done underneathe the coral survial rate is high , clean and less man handling of the corals
