Stiletto some employed a telescoping blade. These Italian switchblades were commonly and popularly referred to as stilettos, since most incorporated a long, slender blade tapering to a needle-like point, together with a slim-profile handle and vestigial cross-guard. The majority of these Italian stiletto switchblade knives used a now-iconic bayonet-style blade with a single sabre-grind edge (often unsharpened) and a long opposing false edge. As with the medieval stiletto, the stiletto switchblade was designed primarily as an offensive weapon, optimized for thrusting rather than cutting. Most of these knives were designed with a locking device which locked the blade in the open
Heel-shaped cairn Heel-shaped cairn The heel-shaped cairn, with its usually cruciform chamber, is a type of megalithic monument that is found in Scotland, especially in Caithness and Sutherland and on the Shetland Islands. On Orkney, the Isbister Cairn is the only site that is similar in shape. The chambers usually lie in a round cairn made of broken rocks, which either contemporaneously or later were surrounded by the eponymous platform, up to 20 metres wide at the front and from 1.0 to 1.5 metres high, and were partly enclosed by large kerbstones. A gentle concave exedra is characteristic of the front face.
