The invention is directed to a weapon or tool head that has an appearance that mimics chipped stone weapon- or tool heads used in prehistory and history. The weapon or tool head has an outer body portion having the desired 'ancient' appearance and a hard insert is provided with at least one sharp edge exposed for use, the latter providing modern performance characteristics to the weapon or tool.

Weapon and tool head and method

The present invention consists of materials and a processing method for coating rigid-rod poly(ionomers) or salts thereof, in a solvent system, directionally on charged surfaces resulting in the formation of liquid crystal display surfaces with planar alignment and pretilt.

Buff-free liquid crystal alignment using poly(ionomer) coatings

A liquid crystal cell including chiral nematic liquid material with negative dielectric anisotropy. The cell is placed between two orthogonal polarizers. In the absence of an applied field, the liquid crystal molecules assume a homeotropic alignment. The liquid crystal molecules assume a twisted pattern in the field-on state.
