The idea was to create an eye-catching knife, whether you use it during the day or night. By day, design based on the absolute contrast of colors helps for its visibility. At night, phosphorescent paint will do the work. Its also very handy for example for night use in the nature - you would never lose knife like this.

This particular design is more elegant than the first one, it depicts a night butterfly - an animal always attracted to the light in the dark (refers to the special ability of this knife).
