Origin: In common use among collectors
"Hairpin forging" or "hairpin laminations" are terms used by collectors to describe a peculiar way of forging that was commonly used in the Himalayan region. The name derives from the sharp bend the laminations take at the apex of the blade.
C.S. Smith referred to it as;
"side-by-side welding of a nested series of hairpin rods"1
In Tibetan, it is called thur.2
