"a rare and
ancient sword named Hrunting. / The iron blade with its ill-boding patterns
/ had been tempered in blood." (Beowulf 1459-60)
"the decorated-blade
came ringing down" (Beowulf 1521)
Boker Knife: These blades are made by a folding process rather than twining
three rods together. The blade though may give you an idea of Hrunting's
"ill-boding patterns."
