Olympic individual silver medallist Sofya Velikaya struck gold on home soil as she triumphed in the women's event at the International Fencing Federation Sabre Grand Prix in Moscow.
Velikaya, a member of the Russian squad which claimed the team title at the 2016 Olympic Games in Rio de Janeiro, beat China's Shao Yaqi 15-9 in the final at CSKA Arena.
The world number one and top seed lived up to her billing as the pre-event favourite with commanding displays throughout the competition.
Velikaya ousted team-mate and reigning world champion Sofia Pozdniakova in a thrilling semi-final.
The 33-year-old double world champion overcame her compatriot 15-13 to book her place in the gold medal bout.
Yaqi joined the Russian star in the final following a 15-9 triumph over Liza Pusztai of Hungary.
Pozdniakova and Pusztai finished the event with bronze.
