if it's the same material as mine, which I think it is, then it be g10. I wear my everyday and have for amost 6 months. Mine rides on my belt though. Damned handy things ain't they?
My girlfriend has one as well, but wears hers as a neck knife. She loves hers too.
My personal Wharnie and the sheath Todd did for it.
When we made mine we also made one for my daughter.
Great review Thrillbilly! These are sweet little blades.
