I recently bought a home. The landscaping wall was not completely finished. I want to finish capping the wall. I havent done this before and I was wondering what type of tool I should use to cut the concrete capping stone. ie. A concrete blade on a circular saw or a brick cutter. Also I dont know if there is any easy way or a method to working out the angles to cut the stone to form the corners. the pictures below may help describe my question.
