What is "shashka"

The Shashka (/ - big knife, ) is a special kind of sabre; a very sharp, single-edged, single-handed, and guardless sword. In appearance, the shashka is midway between a full sabre and a straight sword. It has a slightly curved blade, and can be effective for both slashing and thrusting. The blade is either hollowed or fullered. There is no guard, but a large, curved pommel. The hilt is frequently highly decorated. Shashkas from the Caucausus, as opposed to Russian versions, are carried in a wooden scabbard that encloses part of the hilt. It is worn with the cutting edge to the rear, opposite to the sabre.
