The man is believed to have been using a bat'leth, the traditional yard-long double-pointed scimitar favoured by Klingon warriors.
As everybody knows, the first bat'leth was said to have been created by the first Emperor of the Klingon Empire, Kahless the Unforgettable, who dropped a lock of his hair into the lava from the Kri'stak Volcano, before plunging the lava-covered hair into the lake of Lursor, and twisting it to form a blade.
