Methods of semi-precise breaking of a cinder block in half lengthwise?

I want to use cinderblock halves for the border of an outdoor project, but my question -- how to break them along intended lines without cracking/fracturing the rest of it?

I'd like to break a cinder block (two-hole) lengthwise, that is, down the center of the two holes, so that I'll have two wide "m" shapes. How can I break the cinderblock semi-precisely, without fracturing the rest of it? I'm going to be implanting them into the ground, so the exactness isn't necessarily perfect, as long as I have to flat surfaces on the edges of both halves (two flat tops on the "m" shape) to line up end to end to make a border. Any suggestions of how to accomplish this, without having to buy/rent a concrete chainsaw or drilling perforation holes? Solutions that are slow/tedious are just fine.
