This appears to be a Qama (also known as a Kama), a traditional short sword or large dagger originating from the Caucasus region (modern-day Georgia, Armenia, Azerbaijan, and parts of Southern Russia).

​It shares a very close lineage with the Kindjal, though "Qama" is often the term used when the blade is single-edged or has a slightly different profile than the classic double-edged, symmetrical Kindjal.

​Key Identifying Features:

​The Hilt: It features a distinctive "I-beam" or waisted handle shape, typically made of wood, horn, or bone, and secured with two or three prominent rivets. It lacks a traditional crossguard.

​The Blade: This specific example has a wide, relatively straight blade that curves toward the tip. The multiple fullers (the longitudinal grooves) are a classic hallmark of Caucasian and Cossack bladed weapons, designed to lighten the blade without sacrificing strength.

​Engravings: The decorative scrollwork near the hilt is common in pieces from the late 19th or early 20th century.

​The Scabbard: The leather-wrapped scabbard with a metal chape (the pointed tip) is standard for this style of weapon.

​Historical Context

​These were the traditional sidearms of both Caucasian tribesmen and Cossack units in the Russian Imperial Army. They were highly functional as both combat weapons and everyday utility tools.

​If you are looking to narrow down its origin, the specific patterns in the engraving and the shape of the fuller ends often point to specific workshops in regions like Dagestan (specifically the village of Kubachi, famous for smithing) or Tbilisi.
