The basic katar has a short, wide, triangular blade. Its peculiarity lies in the handle which is made up of two parallel bars connected by two or more cross-pieces, one of which is at the end of the side bars and is fastened to the blade. The remainder forms the handle which is at right angle to the blade. Some handles have long arms extending across the length of the user's forearm. The handle is generally of all-steel construction and may be gilded or otherwise decorated. The blade, typically measuring in length, is usually cut with a number of fullers. Most katar have straight blades, but in
south India they are commonly wavy. South Indian blades are often made broad at the hilt and taper in straight lines to the point, and elaborately ribbed by grooves parallel to the edges. Occasionally the blades are slightly curved. Some blades are forked into two points, and one decorative variation includes a hollow outer blade which hinges open to expose a smaller blade inside. The Indian nobility often wore ornamental katar as a symbol of their social status. The hilts may be covered in enamel, gems, or gold foil. Similarly, figures and scenes were chiselled onto the blade. Sheaths, generally made from
watered steel, were sometimes pierced with decorative designs. The heat and moisture of India's climate made steel an unsuitable material for a dagger sheath, so they were covered in fabric such as velvet or
silk. Some katar served as a sheath to fit one or two smaller ones inside. ==Techniques==
