Saw this over on bladeforums and had to drop it off here!
This is a BUHK Jr. model knife made by custom knifemaker J. Neilson. He does beautiful work, but this is the first time I've seen him....or anyone, for that matter...use Armadillo shell scales! Thought it was cool, and you guys would get a kick out of it. Not particularly attractive, but certainly innovative!
Here's his description of it:
"This is the same BUHK-Jr. but, with stabilized/green dyed Armadillo handle scales with black tang liners. The stainless steel handle bolts have been textured as well to match the rugged surface of the handle scales. This knife has the same dimensions as the standard BUHK-Jr. (B.U.H.K.-Jr. is the same profile as it's big brother just reduced by 1/4 and forged from 1/8" thick 1084HC stock. This slim knife is 6 7/8" overall with a 3 1/4" cutting edge) with an antiqued finish and my molded Kydex sheath with a removable/reversible belt loop."
