The London Hammer (also known as the "London Artifact") is a hammer made of iron and wood that was found in London, Texas in 1936. Part of the hammer is embedded in a limey rock concretion, leading to it being regarded by some as an anomalous artifact.
The soft hammer has a lower yield than the rock, that would make a layman think that it is impossible to carve flint or quartzite with a piece of wood or antler. However, its elastic limit is much higher, which makes it bear more tension and it is the rock that breaks, instead of the hammer. This does not happen, however, with the bone.
London Hammer: Also known as the "London Artifact", a hammer made of iron and wood that was found in London, Texas, in 1936. Part of the hammer is encased in "400-million-year-old" ("Ordovician era") rock. In 1985, anthropologist John R. Cole [40] hypothesized that the stone surrounding the hammer is a historic carbonate soil concretion.
A geologist's hammer, rock hammer, rock pick, geological pick, or informally geo pick is a hammer used for splitting and breaking rocks. In field geology, they are used to obtain a fresh surface of a rock to determine its composition, bedding orientation, nature, mineralogy , history, and field estimate of rock strength.

The ancient works give us a rare glimpse into how native groups of the Orinoco perceived their landscape and made it sacred and instrumental through rock engravings, said George Lau, a professor ...
In using hard hammer percussion the flake tools were made by taking metamorphic or igneous rock such as granite or quartz and striking it against the stone. This method was often used to flake large core flakes of hard rock. Soft hammer percussion is the second step. It involves using a hammer made of bone, which was often antler, in order to ...
