South Korean archer Kim Je-deok recent two gold medal haul at the 2021 Summer Olympics in Tokyo brought praises to South Korean sports equipment manufacturer Win&Win for its graphene-enhanced bow.
Other than Kim's mental strength and athleticism, his victories were partly attributed to his secret weapon: graphene bows.
Kim also aimed for a third gold medal but dropped out of the round of 32 after losing to Germany's Florian Unruh.
Win&Win's WIAWIS brand of bows is made of either aluminum bows or graphene.
The athletes may choose either of the bows depending on their preferences.
Jang Min-hee and An San from South Korea's women's national team chose to use WIAWIS aluminum bows.
Graphene bows can be bent and returned to their original shapes without losing performance quality, according to reports.
Win&Win previously has bows made of carbon nanotubes as their flagship products but replaced them with graphene.
Graphene bows are said to be 60 percent more durable and 20 percent more shock-absorbing than carbon nanotubes.
Win&Win also used graphene in manufacturing bicycles that South Korean national track cyclist Lee Hye-jin chose to ride in the Tokyo Olympics.
