Small iron meteorites may be cut with high‐speed plastic‐bonded carborundum wheels, with hacksaws or automatic modifications of these, and with carbide‐tipped wheels; to date, no simple method has been available for cutting large iron meteorites. The successful sectioning of a 20‐ton meteorite involved the use of a mason's wire‐saw, fed with a slurry of carborundum‐grit. The slab produced measured 1.8 × 1.3 × 0.05 m and could be ground and polished for deep‐etching, with a minimum of weight loss.
