Welcome soldbyjim!
Length, weight and spine thickness can vary by kami.
I've seen them come in at 6in 6oz and seen larger ones at 10in 11oz, I'm not sure of spine on either,as i don't own one. The one thing i can tell you is that by all accounts they are as good a cutter as the Kumar Karda.
I guess we'll both have to see if anyone chimes in with the missing info.:thumbup:
