I have some big slates rescued from a demolition project in my yard.
They are about 3' by 4' and about an inch thick. I'd like to re-
purpose them but I need them smaller than that size. If I could break
that large slate into 4 smaller ones, I'd be thrilled.

How hard is this? What tools would I need? And how would I go about
doing this?

Thanks.

If used for roofing, an edge needn't be too square. Use a pointed rock
hammer or hammer and chisel, and knock divots about every 2 inches
along your desired cut line. Knock 'em pretty deep, about 1/2 inch,
and it'll break off fairly cleanly. Clean up the resultant edge by
hangin the slab over a ridgid surface and knapping away. If a square
edge is desired, use a big wet saw or a diamond bladed cut-off saw. Tom
