biface

(Also, other biface typologies make five divisions rather than four).

Perhaps the first example of a wedge is the hand axe, also see biface and Olorgesailie.

For the latter reason, handaxes are, along with cleavers, known as biface tools.

The cache consisted of a biface, three projectile points, and one red stone bead.

They are defined as "a unifacially retouched projection on a flake or modified biface."

To make microblades by this technique, a large biface is made into a core which looks like a tall carinated scraper.

A palaeolithic biface was found in the parish near Mount Skippett in 1983.

Knapped biface.

In archaeology, a cleaver is a name given to a type of biface stone tool of the Lower Palaeolithic.

A blank is a thick, shaped stone biface of suitable size and configuration for refining into a stone tool.

In archaeology, a biface is a two-sided stone tool, made by chipping off flakes with another tool.

The Acheulean was characterised not by the core, but by the biface, the most notable form of which was the hand axe.

A ficron handaxe is a name given to a type of prehistoric stone tool biface with long, curved sides and a pointed, well-made tip.

The bulk of the biface assemblage can be attributed to the Late Acheulian and Yabrudian industries.

Four of the specimens are on retouched flakes, and four of them are on biface fragments.

Out of the group of stone tools, only a few biface (shaped edges on both sides) knives were found and these were made from chert or chalcedony.

The pit contains fossils of perhaps 32 individuals together with remains of Ursus deningeri and other carnivores and a biface called Excalibur.

The most common stone tool recovered from the site is a chert oval biface and is associated with agriculture and thought to have been used for weeding and hoeing.

A Mode 2 tool is a biface consisting of two concave surfaces intersecting to form a cutting edge all the way around, except in the case of tools intended to feature a point.

Excavations at Cultural Zone 3 at the site have yielded many tiny flakes, retouched flakes, larger biface fragments, points and point fragment, hammers made of quartz, and anvils.

A hand axe or biface is a stone tool with two faces typical of the lower (Acheulean) and middle Palaeolithic (Mousterian), and is the longest-used tool of human history.

It is a true biface tool although not as finely worked as the later handaxe which is worked all over its surface into a more ergonomic shape with pointed tip and rounded butt end.

An Early Acheulean or Abbevillian rolled biface was found by Fleisch in the breccia above Rue Jinnah that predates all of the other tools found at Ras Beirut.

Solutrean and Clovis points share common characteristics: points are thin and bifacial, and they share the intentional use of the "outre passé", or overshot flaking technique, which quickly reduces the thickness of a biface without reducing the width.

This theory does not mean that Clovis showed up and had the fluted biface technology, but assumes that over about 1,000 years the original settlers developed the technology, and Clovis was the first successful material culture in America that became widespread.
