I see a slender, silvery, medium-length blade with a toothed edge, and a black handle at the hilt. It has a slight curve, adding a unique aesthetic. The smooth gleam of the metal could be suggested by light, cool grays or blues, while the handle can be a bolder black or charcoal. The serrated blade could be portrayed as a gradient of lighter, shaded blues or grays. To show the curve of the item, gradient shades of the same color could be used to suggest depth.
