The story behind this knife

Paired with a blue dyed walnut handle, shaped perfect for a pinch grip hold with the raised back and narrow front fitting the palm of the hand perfectly.

Handle detail
One of one. Never to be repeated.
The colouring here is very dark, as the photos struggle to show. Almost black but with deep blue and purple tones. Some banding in the steel is visible in the patina bringing some red tones towards the center.
