These are kukris with black panel blade. Most have the coal forge finishing, straight from the charcoal oven, and few have the black chemical coated blade. Raw blade gives a raw natural look and is very durable since it skips the long machinery process required to polish the blade hence the hardness is maintained. On the other hand, black chemical coated blade is rust-free hence hassle free. Black Chemical Coat or BBC can be opted for any blade through the Add-Ons segment in each knife.
