The then 21-year-old, who also won in this weight division at the Championships held two years earlier in Istanbul, secured a second gold with a 13-8 defeat of Chinese Taipei's Xiang Wen.

Despite losing the final, Wen returned home with the satisfaction of inflicting the biggest upset of the day by beating Turkey's world number one Ali Can Ozcan in the semi-finals, 31-18.

A thrilled Yasur later told World Para Taekwondo: "It was a difficult final. It was the last fight of the day after four matches. I am a second title world champion, I have no words. 

"It's such a wonderful feeling. I love it.

"It's everything that I wanted and everything that I am training for.

"Of course, the next goal and big one is the Paris 2024 Paralympic Games.

"I will try my best to repeat this day in Paralympics, it's a big dream for me and I will do everything to achieve the gold medal."

Although Yasur didn't qualify for the Tokyo 2020 Paralympics, where taekwondo made its debut, he indicated later in the year that he was a Paralympic contender for the future.

Yasur won five fights at the 2021 World Para Taekwondo Championships in Turkey, beating the European champion in the semi-finals and defeating home athlete Ozcan 57-42 in the final.

"I still haven't absorbed it," Yasur told the Times of Israel after his victory. 

"I am happy, and I am the happiest person for the path I chose, for the medal, and for this crazy day."

Other crazy days lay ahead for the young man who lost both his arms below the elbow as a 13-year-old after accidentally grabbing hold of a live cable while retrieving a football from an electrical installation near his home in northern Israel.

In the years that followed he was determined to embrace a sport that required only the use of his legs, deciding on the Korean martial art of taekwondo because of its focus on legwork.

After his story was covered by the media, members of the public raised donations for him to be fitted with two prosthetic bionic arms that he controls through brain signals.

Yasur is contributing to a rising interest in taekwondo in Israel, for whom Avishag Semberg won Olympic bronze in Tokyo in the women's flyweight under-49kg category.

Speaking after Yasur's first world title win, Israel's Culture and Sports Minister Chili Tropper described him as "a wonderful young man for whom the sky is the limit".

Yasur is continuing to prove the truth of that assessment.
