Amboyna handled chute knife uses CPM-154CM for the blade. 8" hollow grind is mirrored with a 4" hollow grind for the swedge. The Amboyna has some sculpting along the bottom edge. The sheath is a simple leather pouch wrapped in Ostrich leg leather which has lots of character. The blade is around 4" and it's around 8" OAL. Thickness is some where around 0.190. Thanks for having a look...
