The stone tools may have been made by Australopithecus afarensis, the species whose best fossil example is Lucy, which inhabited East Africa at the same time as the date of the oldest stone tools, a yet unidentified species, or by Kenyanthropus platyops (a 3.2 to 3.5-million-year-old Pliocene hominin fossil discovered in 1999).

Pickaxes are commonly carried by Pioneer Sergeants in the British Army. [5] A normal pickaxe handle is made of ash or hickory wood and is about 3 ft (91 cm) and weighs about 2.5 lb (1.1 kg). British Army pickaxe handles must, by regulation, be exactly 3 ft (91 cm) long, for use in measuring in the field. [citation needed] New variant designs are:
Usually, this spike is slightly curved downwards, much like a miner's pickaxe. The term is sometimes used interchangeably with war hammer.

A Petoskey stone is a rock and a fossil, often pebble-shaped, that is composed of a fossilized rugose coral, Hexagonaria percarinata. [1] Such stones were formed as a result of glaciation, in which sheets of ice plucked stones from the bedrock, grinding off their rough edges and depositing them in the northwestern (and some in the northeastern) portion of Michigan's lower peninsula.
Engineered stone is a composite material made of crushed stone bound together by an adhesive to create a solid surface. The adhesive is most commonly polymer resin , with some newer versions using cement mix.
Compared to the Stentoften inscription, the one on the Björketorp stone has a fuller, more formal and less archaic style. [1] Scholars are not in agreement on the purpose of the runestone. It has been suggested that the runestone is a grave and that the curse is intended to protect it.
