Only one side has really been worked on. The black is charcoal used to make the photo clearer. The gray is untouched stone. Once the piece is nearly completed I'll start figuring out how to drill the hole to turn it into a water spout thingy. Tools used, angle grinder with a diamond grinding blade, Trow & Holden 1/2 pneumatic stone carver, various hand chisels (used for home floor tiling) and wood carving rasps. Approx. four hours of work(?), approx. 45 lbs.
